Tetrahydrophthalic anhydride Medicine Raw Material THPA for insecticides and sulfide regulator



Description


Tetrahydrophthalic anhydride by maleic anhydride and 1, 3 - butadiene in the presence of catalyst preparation and the addition reaction of as intermediates in organic synthesis, are commonly used to produce alkyd resins and unsaturated polyester resin, paint, also used as the curing agent of epoxy resin, and also used in pesticide, sulfide regulator, plasticizer, surface active agent and so on.

Usage


As an organic intermediate,THPA is usually used in the production of alkyd and unsaturated polyester resins,coatings and the curing agent for the epoxy resins,and also used in insecticides,sulfide regulator, plasticizers, surfactant, alkyd resin modifier,pesticides and the raw materials of pharmaceuticals.

As raw materials for the production of unsaturated polyester, THPA mainly improved the air-drying performance of resins.The performance is more obvious especially in the production of high-grade resin putty and air - drying coatings.
