In the field of chemistry, acetonitrile and acetonitrile are two common chemical substances. Their names are similar, but in fact there are great differences. This article will give you a detailed analysis of the difference between acetonitrile and acetonitrile to help you better understand these two chemicals.

acetonitrile and acetonitrile differ in chemical structure. The chemical structure of acetonitrile is CH3CN, which is an organic cyanide compound, which is a co-precipitation product of potassium hydroxide and silver cyanide. It is usually colorless crystal and has a pungent smell. The chemical structure of acetonitrile is CH3CH2CN, which is also an organic cyanide compound. It is a colorless liquid at room temperature and has a strong pungent odor. In terms of chemical structure, acetonitrile is an isomer of methyl cyanide, while acetonitrile is an isomer of propionitrile.

acetonitrile and acetonitrile also have some differences in properties. Cyanide is a solid at room temperature, melting point of -13 ° C, boiling point of 82 ° C, volatile, insoluble in water, soluble in ethanol, ether and other organic solvents. Acetonitrile is a liquid at room temperature, with a boiling point of 81-82°C and a density of 0.786g/cm³. It is volatile and soluble in water and ethanol. In terms of nature, acetonitrile is more volatile and has better solubility.

In addition, the use of acetonitrile and acetonitrile is also different. Acetonitrile can be used in organic synthesis, surfactants, dyes, pharmaceuticals, plastics, rubber and other fields. It is an important raw material for organic synthesis, and can also be used to prepare amino acids and methanesulfonic acid acetonitrile. Acetonitrile is widely used in organic synthesis, pesticides, fertilizers, pigments, pesticides and other fields, is an important organic solvent and raw materials.

In general, although the names of acetonitrile and acetonitrile are similar, there are significant differences in chemical structure, properties and uses. Understanding the difference between these two chemicals will help us to better use them and avoid accidents caused by misuse. I hope this article can help you better understand acetonitrile and acetonitrile and better apply these two chemicals.
