What is Carbic anhydride CAS 129-64-6？

Carbic anhydride CAS 129-64-6 precipitated from petroleum ether is orthomorphic white columnar crystal with delixability and melting point 164 ~ 165℃. Slightly soluble in petroleum ether, soluble in benzene, toluene, acetone, carbon tetrachloride, chloroform, ethanol, ethyl acetate. When heated beyond its melting point, it is transformed into a cis-balanced mixture. It reacts with water to form the corresponding acid. It has an irritating effect on the skin mucosa.

Application

Carbic anhydride CAS 129-64-6 is mainly used as curing agent of epoxy resin, suitable for casting, laminating, powder molding and so on. The cured material has excellent weather resistance, heat resistance and electrical properties. The product can also be used as polyester resin, alkyd resin, plasticizer, stability, pesticide raw materials. Some derivatives and their uses are as follows: Diallyl norbornalate is used as a heat-resistant copulator for unsaturated polyesters. This is an excellent epoxy stabilizer of polyvinyl chloride, which can be obtained by esterification and epoxidation of decyl alcohol. The product is also used as a modifier of ureA-formaldehyde resin, melamine resin, rosin, rubber vulcanization modifier, resin plasticizer, surface activator, textile finishing penetrant.
