Title:
ハロゲノ-o-ヒドロキシジフェニル化合物の製造方法
Document Type and Number:
Japanese Patent JP4272271
Kind Code:
B2
Abstract:
There is described a four step process for the production of halogeno-o-hydroxydiphenyl compounds having the formulain which X is -O-or -CH2-;m is 1 to 3; andn is 1 or 2;wherein in the first step, a diphenyl compound is chlorinated; in a second step the chlorinated compound is acylated in a Friedel-Crafts reaction and optionally again chlorinated after the acylation; in a third step the acyl compound is oxidised; and in a fourth step the oxidized compound is hydrolyzed.The compounds of formula (1) are useful for the protection of organic materials against microorganisms.
