What are the physical properties of Cyanoguanidine?
1-Cyanoguanidine is an important chemical substance with unique physical properties. It is a white crystalline powder at room temperature, which is pure and delicate, as white as frost and snow. The density of this substance is about 1.40g/cm ³, and the texture is relatively firm.
When it comes to the melting point, the melting point of 1-cyanoguanidine is quite high, reaching 209-212 ° C. Such a high melting point allows it to maintain a stable solid state at ordinary ambient temperatures. And its chemical structure is stable, and it is not easy to change unless it encounters special conditions.
1-cyanoguanidine has a certain solubility in water. In an appropriate amount of water at room temperature, it can be slowly dissolved to form a uniform solution. However, its solubility is not very high. In organic solvents, such as ethanol, ether, etc., its solubility is relatively poor, and it is mostly dispersed in solid form.
In addition, 1-cyanoguanidine has certain hygroscopicity. In a high humidity environment, it can absorb moisture in the air and cause its own deliquescence. However, its hygroscopicity is still controllable, and it can be properly stored in a dry place to avoid this phenomenon. Its chemical properties in air are relatively stable, and it is not easy to react quickly with common gases such as oxygen. It can maintain its physical and chemical properties for a certain period of time.
Is 1-Cyanoguanidine chemically stable?
For 1-cyanoguanidine, the stability of its chemical properties is related to many things. Try to discuss it in detail. This substance is still stable under normal conditions. If it is at a peaceful temperature and pressure, its molecular structure is well, and it is not easy to change by itself. However, chemical things, every time they encounter other things, their properties may be different. 1-cyanoguanidine encounters strong acid and strong base, just like dry wood near fire, and the reaction will be intense. In strong acid, ions are active, such as tigers entering a flock, interacting with 1-cyanoguanidine molecules, or causing their structure to disintegrate, and new products will be derived. The same is true for strong bases. The properties of hydroxide ions can also lead to the transformation of 1-cyanoguanidine.
Furthermore, temperature is the main cause of chemical changes. If the temperature gradually rises, the 1-cyanoguanidine molecule is energized and its activity increases greatly. At a certain high temperature, the molecular vibration is abnormal, and the chemical bond is like a rope of rotten wood, which is easy to break and cause a reaction. However, at room temperature, if there is no foreign interference, 1-cyanoguanidine is still in a quiet state, and its properties are stable.
Light cannot be ignored. Light of a specific wavelength can carry energy to shoot 1-cyanoguanidine, or stimulate the electron transition of molecules, breaking its steady state and opening the door to chemical reactions. Therefore, if 1-cyanoguanidine is to maintain its properties, it should avoid strong acids and alkalis, control the temperature appropriately, and prevent direct exposure to strong light. In this way, its chemical properties can be safe and free from unprovoked changes.
What are the production methods of Cyanoguanidine?
1-Cyanoguanidine is also an important substance for chemical transformation. The methods for its preparation have coexisted through the ages.
First, it is based on dicyandiamide to perform isomerization. For dicyandiamide, prior to a specific device, a suitable catalyst is used to control its temperature and adjust its pressure. Common catalysts, such as some metal salts, can promote this change. At moderate temperatures, between 100 and 200 degrees, dicyandiamide molecules become endogenous, resulting in 1-cyanoguanidine. In this way, the reaction rate is quite high, and the purity of the product is also good. However, the selection and recovery of catalysts need to be carefully considered, which is related to cost and benefit.
Second, it is prepared by combining cyanamide and guanidine salts. Cyanamide and guanidine salts are mixed in an appropriate proportion into the reaction kettle. Under the medium of alkali, the two are combined. The strength and amount of alkali are the main reasons. If the alkali is too strong and excessive, the side reaction may be raw; if the alkali is weak and low, the reaction is difficult. The temperature is controlled between tens of degrees, and over time, 1-cyanoguanidine can also be obtained. However, impurities or impurities exist in the product, and subsequent purification needs to be improved.
Third, urea and cyanamide can also be used as sources. Urea is first pyrolyzed, cyanic acid is produced, and cyanic acid and cyanamide meet to form 1-cyanoguanidine in a suitable In this way, the raw materials are easy to obtain, but the pyrolysis process is difficult to control the temperature, and the side effects are complicated, and the separation and purification of the product is not easy. If you want to obtain high-purity 1-cyanoguanidine, you need to be careful about the reaction.
All kinds of production methods have advantages and disadvantages. The industry should choose the method according to the supply of raw materials, the calculation of cost, and the demand for products, so as to achieve the good preparation.
What are the precautions for the storage and transportation of Cyanoguanidine?
1-Cyanoguanidine is also a chemical substance. During storage and transportation, many things to pay attention to must be observed.
When storing, the first dry environment. This material likes to dry, and if it is in a humid place, it is prone to moisture and deterioration, which will damage its inherent properties. Therefore, it is necessary to choose a dry place and hide it in a container to prevent moisture from invading.
The second is temperature control. Do not use a place with high temperature, high temperature or cause its chemical properties to change, or even risk danger. Under normal temperature, properly placed to keep it stable.
Furthermore, avoid other miscellaneous places. 1-Cyanoguanidine encounters with certain substances, or reacts chemically, causing accidents. Such as strong acids and alkalis, they should be kept away to avoid disasters.
As for transportation, the packaging must be solid. Wrap this thing with shock-resistant and collision-proof materials, and it will be bumpy on the way, so as not to damage and leak.
The person transporting it also needs to be clear about its nature. Know the emergency method. In case of leakage, etc., it can be dealt with quickly to avoid major disasters. The transportation vehicle should also be clean, free from other objects, and keep the purity of 1-cyanoguanidine. In this way, it is suitable for storage and transportation, so that 1-cyanoguanidine can be kept safe and safe.
