What are the physicochemical properties of N-Acetylguanidine?
N-acetylguanidine is also an organic compound. Its physicochemical properties are quite critical, and it has many applications in the field of chemistry.
In terms of its properties, under normal conditions, or white crystalline powder, the appearance is fine, which is characterized by appearance. As for the melting point, it is about 110-115 ° C. In case of this heat, the material state gradually changes, and gradually melts from the solid state. This is the property of its thermal change.
Solubility is also an important property. N-acetylguanidine is soluble in water and can disperse and dissolve in water to form a uniform system. This property makes it useful in reactions or applications related to aqueous solutions. And it also has some solubility in some polar organic solvents, such as ethanol, can also be partially dissolved, but in non-polar solvents, such as n-hexane, it has little solubility or almost insoluble.
In terms of stability, N-acetylguanidine is relatively stable in a normal temperature and dry environment, and can be stored for a long time without significant chemical changes. However, if placed at high temperature, high humidity, or in contact with specific chemicals, the stability will be affected. In case of strong acid and alkali, chemical reactions can occur, and its molecular structure may be damaged, thereby changing its chemical properties and uses.
This compound is widely used in the field of organic synthesis and is often used as an intermediate to participate in many reactions, providing a basis for the preparation of more complex organic compounds. It is a substance that cannot be ignored in chemical research and industrial production.
What is the preparation method of N-Acetylguanidine?
For N-acetylguanidine, there is a way to prepare it. The method starts with guanidine and is obtained by the reaction of acetylation.
For guanidine, it is also an organic base. To make N-acetylguanidine, guanidine salt and acetylation reagent are often taken together. For example, guanidine hydrochloride is mixed with acetic anhydride. The two are chemically reacted at an appropriate temperature and within an appropriate time.
When the hydrochloride of guanidine meets acetic anhydride, the acyl groups in acetic anhydride are electrophilic, and the nitrogen atoms in guanidine molecules have solitary pairs of electrons and are rich in nucleophilicity. The nitrogen atom then attacks the carbonyl carbon of acetic anhydride, and the carbonyl double bond of acetic anhydride is opened to form an intermediate. After the intermediate is transferred and eliminated by protons, N-acetylguanidine is finally obtained, and acetic acid is formed at the same time.
Acetyl chloride can also be used to replace acetic anhydride as an acetylation agent. However, acetyl chloride has high activity and the reaction is more violent. Careful temperature control and reaction conditions are required. During the reaction, guanidine and acetyl chloride react slowly in suitable solvents, such as dichloromethane and ether. Because acetyl chloride is hydrolyzed in contact with water, the reaction system needs to be dried.
During the preparation process, temperature control is very important. If the temperature is too low, the reaction is slow, it lasts for a long time and the yield is low; if the temperature is too high, the product will be impure due to side reactions. And, after the reaction is completed, the product is often purified by distillation, recrystallization, etc., to obtain pure N-acetylguanidine, which is suitable for experimental or industrial needs.
What is the price of N-Acetylguanidine in the market?
In today's world, it is difficult for us to judge the price of N-Acetylguanidine in the market. The market situation is fickle, and the price also fluctuates with many factors, such as the trend of supply and demand, the abundance of production sources, the difficulty of craftsmanship, and the stability of the current situation. All determine the price.
In the past, when the supply and demand of this product were relatively stable, the production sources were sufficient, and the craftsmanship was mature, the price would be stable and appropriate. However, if the world is chaotic, or the source of production is damaged due to natural disasters, or there are many people seeking it and there is not enough supply, the price will soar.
Furthermore, the difference in origin is also related to the price. If the product is abundant in material resources and the labor is cheap, the price may be better than elsewhere. Whether the process is advanced or not also affects the cost and quality, which in turn affects the selling price.
Therefore, if you want to know the exact market price of N-Acetylguanidine, you should go to the pharmaceutical and chemical industries, consult the merchants, or visit the industry experts, and observe the recent transaction records. Only then can you get close to the real price, not what we can guess on paper.
What are the safety and precautions for N-Acetylguanidine?
N-acetylguanidine is one of the organic compounds. When it comes to its safety, it is necessary to be careful.
On the toxic side, although there is no detailed ancient record to compare, today's studies show that in animal experiments, if used in large doses, it may damage the body. For example, it may cause abnormal function of the liver and kidneys. In the liver, it may disturb its metabolic ability; in the kidneys, or hinder its excretion.
Also speaking of environmental effects. If this substance enters the environment, it may be difficult to degrade due to its chemical properties. Or it may accumulate in soil and water, thus endangering the ecological balance. Such as in aquatic ecology, or harmful to the survival and reproduction of aquatic organisms.
Re-discussion of the precautions of use. In the laboratory, those who handle this object must wear protective gear, such as gloves and goggles, to prevent it from touching the skin and entering the eyes. If you accidentally touch it, quickly wash it with plenty of water. And when operating, it is suitable to be in a well-ventilated place to prevent it from entering the body. When storing, keep it in a cool, dry place, protected from fire and heat sources, and seal it to prevent deterioration and leakage. If there is a leak, quickly clean the dirty place and dispose of the waste in a special way, and do not discard it at will.
In summary, although N-acetylguanidine may have its uses in chemical, pharmaceutical, and other fields, when it is used, it is necessary to carefully check its safety and abide by the operating regulations to ensure the safety of people and the environment.
