Butyric anhydride/CAS：106-31-0

 Usage

Butyric anhydride is mainly used as an acylating reagent in organic synthesis. It can react with alcohols, phenols, amines, etc. to form corresponding esters, phenyl ethers, amides and other compounds. Butyric anhydride can also be used as a raw material for coatings, dyes and plastics. Butyric anhydride can be prepared by reacting butyric acid with acetic anhydride. The reaction conditions are usually carried out under acidic conditions and at low temperatures. Butyric anhydride is irritating and corrosive and may cause irritation to the eyes, skin, respiratory tract and digestive system. During operation, care should be taken to avoid contact with the skin and eyes, and ensure that the operation is carried out under well - ventilated conditions.
