PROCESS FOR PREPARING 4-ALKYLPYROCATECHING OF GENERAL FORMULAWHEREIN R IS TERT-, TERT-, TERT--CH-, TERT--CH,SEC--CH, --CH, TERT--CH, CYCLO--CH

摘要

FIELD: organic chemistry. SUBSTANCE: claimed invention can be utilized in synthesizing alkylpyrocateching by alkylating pyrocateching with appropriate alcohols is the presence of catalyst. In order to synthesize wide range of 4-alkylpyrocateching and to increase the yield of products, alkylation is carried out without solvent using two-fold excess of alcohol and phosphoric acid. EFFECT: more efficiency preparation process.
