Read： 1010 Time：10months ago Source：Transform the World with Simplicity

Acetone cyanohydrin is an important organic chemical raw material with unique properties and a wide range of uses. This article will detail the properties, production methods, safety and main uses of acetone cyanohydrin.

1. the properties of acetone cyanohydrin

acetone cyanohydrin is a colorless or slightly yellow transparent liquid with a pungent odor. It has a strong toxicity, flammable, fire, high heat or contact with oxidants have caused the risk of combustion. Acetone cyanohydrin has a higher boiling point and lower vapor pressure, making it easy to store and transport. In addition, it is soluble in water, ethanol, ether and other solvents.

2. acetone cyanohydrin production method

acetone cyanohydrin production method mainly has two kinds: acetone method and acetylene method. The acetone method is an addition reaction of acetone and hydrocyanic acid in the presence of a catalyst to produce acetone cyanohydrin. The acetylene rule is the addition reaction of acetylene and hydrocyanic acid under the action of a catalyst to generate acetaldehyde cyanohydrin, which then reacts with acetone to generate acetone cyanohydrin.

3. acetone cyanohydrin
Because acetone cyanohydrin has strong toxicity, it is necessary to strictly abide by the safety operation procedures in the production process to ensure the safety of employees and the environment. In addition, in the storage and transportation process also need to pay attention to fire prevention, explosion prevention and other measures.

4. the main uses of acetone cyanohydrin

1. production of methyl methacrylate (MMA)

acetone cyanohydrin is the production of methyl methacrylate (MMA) one of the important raw materials. Methyl methacrylate is a polymer compound with excellent transparency, weather resistance, chemical resistance and other properties, widely used in construction, automobiles, electronic appliances and other fields.

2. production of pesticides

acetone cyanohydrin can be used to produce a variety of pesticides, such as carbaryl, fenitrothion and so on. These pesticides play an important role in controlling pests and diseases and improving crop yields.

3. production of pharmaceutical intermediates

acetone cyanohydrin can also be used to produce a variety of pharmaceutical intermediates, such as acrylonitrile, acetonitrile and so on. These compounds are important raw materials for the synthesis of antibiotics, vitamins and other drugs.

In conclusion, acetone cyanohydrin, as an important organic chemical raw material, has broad application prospects in the field of chemical production raw materials.
