What are the main uses of benzene sulfonate?
Gypsum is a genus of minerals, and its main uses are various, and it has important functions in many fields.
First, medical use is essential. "Shennong Materia Medica" has long been recorded, gypsum-induced cold, with the effect of clearing away heat and purging fire, relieving muscle and diathermy. In the disease of hot topic of heat and thirst, it is often used in combination with Anemarrhena, which is equivalent to playing the work of clearing the air and dividing the real heat; it can help clear the lungs and heat, relieve cough and reverse cough, and is compatible with ephedra and almonds, etc., and the external use can produce muscle and astringent sores.
Second, it is widely used in industry. In cement production, gypsum is an indispensable retarder, which can effectively adjust the setting time of cement. Adding appropriate amounts can maintain good fluidity of cement during mixing, transportation and construction, avoid excessive hardening, and ensure smooth construction. In the paper industry, gypsum can be used as a filler, which can improve the smoothness, whiteness and opacity of paper, and improve the quality of paper. In the ceramic industry, it is also often used as a barren raw material to reduce the shrinkage of the green body, enhance the strength of the green body, and improve the quality of ceramic products.
Third, it also plays a role in agriculture. Gypsum can improve soil. For alkaline soil, it can provide calcium ions, replace sodium ions on soil colloids, reduce soil alkalinity, improve soil structure, and increase soil aeration and water permeability. At the same time, it can supplement crops with nutrients such as sulfur and calcium to promote crop growth. Appropriate application of gypsum to some calcium-loving crops such as peanuts and soybeans can help improve yield and quality.
What are the effects of benzene sulfonate on the environment?
Garlic anhydride is also a chemical substance. The shadow of the environment is deep and cannot be ignored.
If garlic anhydride is in the air, it can cause the reaction of general materials. or generate new compounds, and such new compounds, which are irritating, can harm the respiratory system of organisms, causing them to cough, asthma, and in severe cases, it can affect the function of their lungs. And it is in the atmosphere or photochemical reaction, which can balance the transformation of the environment, making the environment bad, and it can affect the weather.
If it flows into the water, it is also harmful. Garlic anhydride can change the acidity of the water and make the water acidify. Aquatic organisms exist in a fixed amount of water, acidification of water, and transformation of the living environment of crabs, etc. or their external properties, or their physiological properties, causing their reproduction and quantity to be reduced, breaking the balance of aquatic life.
Furthermore, if garlic anhydride is added to the soil, it can change the chemical properties of the soil. or change the solubility of the soil, and plants can absorb the required nutrients, resulting in poor growth. And it may affect the activity of microorganisms in the soil, and the separation of microorganisms in the soil is very important. Its activity is blocked, and the fertility of the soil is lost, endangering the health of the soil.
Of course, the air, water, and soil of the garlic-acid anhydride-environment all have adverse effects, breaking the balance of life. I am careful to prevent it, so as to ensure the safety of the environment.
What are the precautions for benzene sulfonate in industrial production?
Sucrose anhydride, in industrial production, there are many things to pay attention to.
The quality of the first raw material. Both sucrose and acid anhydride must be pure and free of impurities. If sucrose contains impurities, or causes the reaction to be skewed, the product is impure; acid anhydride must also meet the standard, and its purity and activity are all related to the effect of the reaction. If the raw material is not good, although it is difficult to cook without rice, the sucrose anhydride produced will be difficult to meet the requirements.
The second time is the condition of the reaction. Temperature is the most critical. If it is too high, the reaction will be too fast, prone to side reactions, and the product will be complex; if it is too low, the reaction will be slow, time-consuming and laborious, and the yield will not be high. Therefore, it is necessary to accurately control the temperature, and The pressure cannot be ignored. Appropriate pressure can promote the progress of the reaction, but improper pressure may affect the reaction rate and equilibrium. In addition, the reaction time also needs to be considered. If it takes a long time, the energy consumption will increase, and the product may decompose and deteriorate; if it is short, the reaction will not be completed, and the yield will not reach expectations.
Furthermore, the choice and use of catalysts. Suitable catalysts can significantly increase the reaction rate and reduce the energy required for the reaction. However, there are various types of catalysts, each with its own scope of application. The reaction mechanism must be studied in detail, the suitable catalyst should be selected, and its dosage should be controlled. If it is too little, the catalytic effect will not be obvious; if it is too much, it may increase the cost or affect the quality of the product.
In addition, the reaction equipment and The equipment needs to be sturdy and durable, and can accurately control temperature, pressure and flow. The process should be simple and efficient, and the purity and quality of the product can be guaranteed. If the equipment is outdated and the process is outdated, it is difficult to make high-quality sucrose anhydride.
Repeat, safety protection and environmental considerations. During the production process, or involving hazardous chemicals, when operating, it is necessary to strictly abide by safety procedures and prepare protective equipment to prevent problems before they occur. And after production, the waste and exhaust gas should be properly disposed of, in line with environmental protection regulations, so as not to pollute the environment.
All these are the ones that should be paid attention to in the industrial production of sucrose anhydride, and need to be treated with caution in order to make the production smooth and produce good products.
What are the physical and chemical properties of benzene sulfonate?
Borax is a common mineral with unique physical and chemical properties and important uses in many fields.
In terms of physical properties, borax usually appears as a colorless translucent crystal or a white crystalline powder. Its crystal form is usually plate or columnar, with a glassy surface, brittle and easily broken. The density of borax is about 1.73 g/cm3, which is relatively light. And its Mohs hardness is low, about 2 to 2.5, which is similar to the hardness of gypsum, and can be scratched on the surface by nails. Borax has special solubility. It is easily soluble in water and has higher solubility in hot water. It also has a certain solubility in glycerol, but it is difficult to dissolve in organic solvents such as ethanol and ether. In addition, borax will gradually lose its crystalline water when heated, and when the temperature reaches a certain level, it will melt into a glassy substance.
In terms of chemical properties, the chemical name of borax is sodium tetraborate decahydrate, and the chemical formula is Na ² B O · 10H ² O. In aqueous solution, borax will undergo hydrolysis and appear alkaline. The borate ions produced by hydrolysis can combine with hydrogen ions in water, which increases the concentration of hydroxide ions in the solution. Borax has a certain buffering effect and can maintain the pH value of the solution relatively stable. When a small amount of acid or alkali is added to the borax solution, the pH value of the solution does not change significantly. Borax can also react with a variety of metal ions to form complexes with specific colors or properties. This property is often used for the identification and separation of metal ions in analytical chemistry. In addition, borax can participate in a variety of chemical reactions under certain conditions, such as reacting with acids to form boric acid.
Due to these unique physical and chemical properties, borax is widely used in glass, ceramics, medicine, agriculture and many other fields, and plays an important role in industrial production and daily life.
How benzenesulfonate is stored and transported
Those who have alisine have a lively nature. If you want to preserve it and smooth its transportation, you must do it by law.
The way to store it is first and foremost low temperature. At room temperature, alisine is easy to change and lose its essence. If it is placed in a cold place, such as an ice cellar, its sex is safe and its activity can be extended. Cover the cold can condense its gas and converge its essence, so that it does not move rashly and keeps it intact.
The second time, it avoids oxygen. Oxygen is the medium for the change of all things. Alisine often reacts when it encounters oxygen, and its effect is damaged. Therefore, it is hidden in a sealed device, and oxygen is excluded from the outside, and alisine is Ning. You can choose a porcelain bottle and a ceramic jar, which is tightly sealed and blocks oxygen from entering, so that it can last for a long time.
As for transportation, there are also tips. First, you still need to keep a low temperature on the way. Carry it on ice, or wrap it in cold felt to keep it cool and unchanged. Second, slow down. Allianine is delicate, bumpy and vibrating, and it is easy to cause it to disperse and lose its effectiveness. Therefore, the operator should slow down and drive steadily to avoid its tipping and collision, so that allianine can arrive safely.
In this way, allianine can be well stored and transported smoothly, and its effect can be complete, which is also beneficial to people's health.
