Acrylonitrile is a clear, flammable liquid with a strong, sharp odor and is toxic in nature. It has limited solubility in water but readily dissolves in most organic solvents. As a conjugated unsaturated nitrile, its molecular structure includes a carbon-carbon double bond and a cyano group, which allow it to undergo various reactions. These include hydration to form acrylamide and acrylic acid, diene synthesis with dienes, hydrogenation to produce propionitrile and propylamine, copolymerization with acrylamide, electrolytic coupling to create adiponitrile, and serving as a cyanoethylation agent for alcohols and amines.

FAQ

Q1: What are the preparation of acrylonitrile?

A: At present, the propylene ammonia oxidation method has the most industrial production value. Using propylene, ammonia, air and water as raw materials, they enter the ebullating bed or fixed bed reactor according to a certain proportion. Under the action of the phosphorus molybdenum bismuth or antimony iron series catalyst using silica gel as the carrier, the reaction mixture is heated at a temperature of 400 to 500°C. And under normal pressure, acrylonitrile is generated. Then use dilute sulfuric acid to remove unreacted ammonia in the neutralization tower, and then absorb acrylonitrile and other gases with water in the absorption tower to form an aqueous solution. The acetonitrile is separated from the aqueous solution through the extraction tower, and the hydrocyanic acid is removed in the dehydrocyanic acid tower and dehydrated. , distillation to obtain acrylonitrile products.
