PROCESS FOR THE MANUFACTURE OF P-TERT.BUTYLBENZALDEHYDE AND ITS DERIVATIVES HALOGEN-SUBSTITUTED AT THE NUCLEUS AND SOME NEW P-TERT.BUTYLBENZAL BROMIDE DERIVATIVES THEREFOR

摘要

p tert - butylbenzaldehyd and halogen substituted derivatives of the core are produced by bromierung of p - ments.- butyltoluol and its to the core by halogenated derivatives of seitenkettenhalogenierungsbedingungen replaced: to benzalbromidstufe and whose saponification.;in order to transfer of beigemengten p - ments.- butylbenzylbromid and its to the core by halogenated derivatives in the corresponding aldehyde to be replaced: during or after the saponification ch20 and nh3 or hexamethylenetetramine in aqueous lsolution added and heated.;p tert - butylbenzalbromid and its core, halogen substituted derivatives of the formula:where x = h, f, cl, br, j.
