What are the uses of the products of methyltetrahydrophthalic anhydride? Methyltetrahydrophthalic anhydride is a high-precision chemical substance. The products produced are synthesized by a very unique secret recipe. The products of methyltetrahydrophthalic anhydride are generally pure It is very high. What use do we say below the products of methyltetrahydrophthalic anhydride?

Methyltetrahydrophthalic anhydride products are mainly used as curing agents for epoxy resins and also used in synthetic methods such as unsaturated polyester resins, epoxy curing agents, pesticide intermediates, and potting of dry-type transformers.

Derived from the reaction of isoprene and maleic anhydride. The industrial synthesis of methyl tetrahydrophthalic anhydride is obtained by isomerizing maleic anhydride and methyl butadiene through diene synthesis.

The product of methyltetrahydrophthalic anhydride, cracking raw material C5 is pretreated by DMF extraction distillation, cutting the middle distillate rich in methylbutadiene, and reacting with maleic anhydride in a solvent. After the reaction is over, the unreacted components are evaporated, and then isomerized into liquid acid anhydride, and the finished product is obtained through vacuum distillation. The C5 fraction extracts the remaining part of methyl butadiene to catalyze the synthesis of semi-polished resin, and the by-product mineral spirits.
