Benzenesulfonic Acid Monohydrate

Borax monohydrate is the form of borax containing crystalline water. It has many main uses and has been used in many fields in ancient times. In medicine, borax monohydrate has the effect of clearing away heat and detoxifying, reducing swelling and antiseptic. As contained in the "Compendium of Materia Medica": "Borax is sweet, slightly salty, cold in nature, and non-toxic. It is used to treat swelling and pain in the throat, sores on the mouth and tongue, and red eyes." Ancient physicians often used it to formulate medicines for the treatment of throat inflammation, oral ulcers, etc. Borax monohydrate is finely ground and blown on the affected area to reduce swelling and pain, and promote wound healing. In the field of alchemy and process production, borax monohydrate also plays an important role. During alchemy, it can be used as a flux to reduce the melting point of ore, promote better melting reaction of minerals, and help refine medicinal pills. In the glass firing process, the addition of borax monohydrate can improve the heat resistance, transparency and chemical stability of the glass. For example, in ancient glaze firing, borax can make the glaze more uniform in texture, brighter in color, and enhance its durability. In daily life, borax monohydrate is also used. In food processing, it was used in the past to increase food toughness and preservative. But now it has become clear that it has certain toxicity and cannot be used for food addition. In the printing and dyeing industry, borax monohydrate can be used as a mordant to help dyes adhere better to fabrics, making dyeing more uniform and firm, and colors more vivid and lasting. Borax monohydrate has played an important role in ancient medicine, craftsmanship, daily life, and many other aspects. Although some uses have been abandoned due to cognitive changes, its value in the historical process cannot be ignored.

Borax monohydrate is an important inorganic compound. Its physical properties are unique and detailed as follows: Looking at its appearance, borax monohydrate is often a white crystalline powder with a fine texture, just like the first snow in winter. It is pure and white, and shimmers in the sun, giving a sense of purity. When it comes to solubility, this compound is easily soluble in water and can be rapidly dissociated in water. When borax monohydrate melts with water, it is like ice and snow meeting the warm sun, quietly disappearing in water to form a uniform solution. When the water temperature rises, its solubility also increases significantly, which is crucial in many industrial and experimental applications. When it comes to density, borax monohydrate has a specific value, which makes it exhibit a unique behavior during the mixing and separation of substances. Due to its density difference, it can be distinguished from other substances by specific methods, and plays a key role in the purification process of chemical production. When talking about the melting point, borax monohydrate will undergo a physical state change when it is heated to a certain temperature. When the temperature rises to the melting point, the originally solid borax monohydrate gradually softens, melts, and turns into a liquid state. The characteristics of this melting point are of great significance in the field of material processing, which determines its application range and conditions in high temperature environments. In addition, the stability of borax monohydrate is also an important physical property. In the normal environment at room temperature and pressure, it can exist stably and its chemical properties are relatively stable. However, if the ambient temperature, humidity and other conditions change significantly, its stability may be affected, which may lead to changes in physical or chemical properties. In summary, the physical properties of the white crystalline powder of borax monohydrate, such as its appearance, solubility in water and solubility changing with temperature, specific density, clear melting point and certain stability, make it widely used and valuable in many fields such as chemical industry, medicine, metallurgy, etc.

Borax monohydrate is a very important chemical substance. When storing and transporting, many matters need to be paid careful attention. First of all, storage must be placed in a dry place. Because of its certain water absorption, if the environment is humid, it is easy to deliquescence, which will affect its quality and purity. If placed in an open and humid place, borax monohydrate may gradually melt into paste and lose its original properties. Second, it should be stored in a cool place. High temperature can easily cause it to decompose or undergo other chemical changes, which will damage its chemical properties. If it is exposed to the hot sun or a near-high temperature heat source during the hot season, the internal structure of borax monohydrate may be damaged. Third, it needs to be isolated from acidic substances. Borax monohydrate is alkaline and in contact with acidic substances, it is easy to cause chemical reactions and cause deterioration and failure. If it is placed in the same place as common acids such as acetic acid, the reaction will be triggered immediately. As for transportation, first ensure that the packaging is in good condition. If the packaging is damaged, borax monohydrate or leakage will not only pollute the surrounding environment, but also pose safety hazards. If the packaging is torn by collision during transportation, borax monohydrate will be scattered, or affect the transportation vehicle and surrounding goods. Second, avoid violent vibration and collision. Violent vibration collisions may cause changes in its physical state, or even cause chemical reactions. If the vehicle is bumpy and violent during transportation, the friction between the borax monohydrate particles will increase, or heat will cause changes. Third, it must be transported in accordance with relevant regulations. Because it is a chemical substance, the transportation must follow the laws and regulations of chemical transportation to ensure the compliance and safety of the transportation process. If the transportation qualification needs to be complete, the transportation documents must be complete, otherwise it will face legal risks.

The chemical stability of borax monohydrate is related to many aspects. To understand its stability, its structure and properties should be investigated. The chemical formula of borax monohydrate is $Na_2B_4O_5 (OH) _4 · H_2O $. In this compound, boron atoms are connected to oxygen, hydroxide and water molecules in a specific way. Boron atoms are often hybridized with $sp ^ 2 $and $sp ^ 3 $to build a complex structure. In its structure, the strength of boron-oxygen bonds is quite high, which is a key factor affecting its stability. Boron-oxygen bonds are relatively large, and more energy is required to break this bond, so borax monohydrate is endowed with certain stability. Under normal temperature and pressure, borax monohydrate is relatively stable. Its crystal structure is arranged in an orderly manner, and the existence of lattice energy also helps to maintain its stability. Lattice energy refers to the electrostatic interaction energy between ions in ionic crystals. This energy promotes the close arrangement of ions and enhances the stability of the crystal. However, the stability is also affected by external conditions. When the temperature rises, borax monohydrate may lose water. The interaction between water molecules and borax structures will be weakened due to intensified thermal motion. When the temperature reaches a certain level, water particles escape, and borax monohydrate is converted into anhydrous borax or other dehydrated products, and the stability changes accordingly. Furthermore, pH also affects its stability. In an acidic environment, borax monohydrate can react with acids. Due to the alkalinity of borax, hydrogen ions in the acid will combine with oxygen atoms or hydroxides in the borax structure, breaking the original chemical balance, resulting in changes in the structure of borax monohydrate and reduced stability. In an alkaline environment, if the alkalinity is not strong, borax monohydrate can still maintain a relatively stable state; if the alkalinity is extremely strong, it may cause some chemical bonds in the borax structure to break or rearrange, affecting its stability. In summary, the stability of borax monohydrate is determined by its own structure, and it is relatively stable in normal temperature and pressure, neutral and moderate environments. However, changes in external factors such as temperature and pH can have a significant impact on its stability.

In the past, alchemists and pharmacists were in alchemy houses and medicine huts, and after years of practice, they have obtained many ways to prepare. One method is to take pure aluminium stone, put it in a crucible, and heat it slowly. During this period, you need to take care of the heat carefully, and do not make it too much or too little. When the aluminium stone gradually loses its crystalline water, the shape changes slightly, and then spray it with an appropriate amount of water to make it moderately hydrated, and finally obtain the aluminium stone-water-grass complex. In this process, the control of the heat is the key, and the fire is fierce, and the aluminium stone loses too much water, making it difficult to form a water-grass compound; if the fire is small, the hydration is uneven, and the product is impure. Another method is to choose high-quality alum stone and grind it into a fine powder, put it in an appropriate amount of water, and stir it slowly with a wooden spoon to fully dissolve it. Then, move the solution to a shallow bottom container and place it in a ventilated and warm place to allow the water to evaporate slowly. When a crystalline film appears on the surface of the solution, carefully let it stand and let it crystallize naturally. This crystalline material is mostly alum stone monohydrate. However, this process needs to prevent dust from falling in, and the temperature and humidity of the environment also affect it. If it is too warm, it crystallizes too quickly and the crystal shape is not good; if it is too wet, the water evaporates too slowly, which takes a long time. Furthermore, alum stone and specific drugs are co-placed in a kettle and boiled with water. After a certain period of time, the residue is filtered off, and the resulting liquid can also be obtained according to the above evaporation and crystallization method. The choice of the specific agent is related to the purity and yield of the product, and it needs to be done carefully according to the characteristics of the aluminite and the experience of the predecessors. All these preparation methods depend on the experience and care of the operator. A balance can be found between many factors such as temperature, water volume, and time to obtain a pure and suitable aluminite monohydrate.
