What is Carbic anhydride CAS 129-64-6？
Norbornoleic anhydride 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.
