2,2-BIS(3,5-DISUBSTITUTED-4-HYDROXYPHENYL)PROPANE DERIVATIVE, PROCESS FOR PRODUCING THE SAME, AND PROCESS FOR PRODUCING PYROGALLOL THEREFROM

摘要

A 2,2-bis(3,5-disubstituted-4-hydroxyphenyl)propane derivative represented by general formula (1); and a process for producing pyrogallol industrially by decomposing the derivative with an alkali or acid without resort to natural starting material, wherein R<1> represents hydrogen or lower alkyl. The derivative is a novel compound and per se has the activity of controlling aquatic attached organisms required of the active ingredients of antifouling paints for ship bottoms, fishing nets, and so forth. <CHEM>
