What is Chlorendic anhydride?
Chemical properties
WHITE CRYSTALLINE POWDER OR CHUNKS
The Uses of Chlorendic anhydride
chlorendic anhydride are reactive flame retardant for unsaturated polyester, polyurethane and epoxy resins, are used as epoxy curing agents. The epoxy products resistance is good of the heat distortion temperature about 180 ℃.
The Uses of Chlorendic anhydride
In preparation of polyester resins.
The Uses of Chlorendic anhydride
Chlorendic anhydride is used in the synthesis of polymers, used in production of fiberglass-reinforced resins for chemical industry equipment. It can be used to make alkyd resins for use in special inks and paints. It is used as a hardening agent in epoxy resins used in manufacture of printed circuit boards
Flammability and Explosibility
Non flammable
Purification Methods
Steam distil the anhydride or recrystallise it from H2O to yield pure diacid. The pure diacid yields the anhydride with Ac2O. [Prill J Am Chem Soc 69 62 1947.]
