Physical and Chemical Properties | Properties The molecular structure of propionic anhydride acetate contains two unsaturated groups, carbonyl and ester groups. The existence of these two active groups makes propionic anhydride acetate have higher reactivity, which can undergo oxidation, reduction, addition, substitution, transesterification, hydrolysis and other reactions. |
Use | Use Propionic anhydride acetate is a new type of biomass-based chemical product with high application prospects. It can be used as perfume, solvent, plasticizer, oil additive and important chemical intermediates, etc. Further conversion can also produce other downstream functional molecules. |
