Acetic   anhydride


     Acetic Anhydride is an important organic chemical raw material, it is mainly applied in manufacturing cellulose acetate, among which cellulose diacetate is used to make cigarette filter tips and plastics, and cellulose triacetate as raw material to make high-grade light sensing film. Acetic Anhydride can also be used in pharmaceuticalsdyestuffagricultural chemicalsmilitaryperfume industries and metal buffing etc.
