A nuclear substituted salicylic acid represented by the following general formula (I):
(in the formula (I), R₁ represents a methyl group, an isopropyl group, a tert-butyl group, a tert-amyl group, a tert-hexyl group, a tert-octyl group, an α , α -dialkylbenzyl group or a nuclear substituted α , α -dialylbenzyl group; and R₂ represents a tert-butyl group, a tert-amyl group, a tert-hexyl group, a tert-octyl group, an α , α -dialkylbenzyl group or a nuclear substitutedα , α-dialkylbenzyl group) and a salt thereof are herein disclosed. The novel nuclear substituted salicylic acids and salts thereof according to the present invention have good solubility in water, organic solvents or organic polymeric compounds and, therefore, these compounds are very favorable as bactericidal and germicidal agents, stabilizers for polymeric compounds or color developing agents for recording materials.
由以下通式(I)代表的核取代水杨酸:
式(I)中,R₁代表甲基、异丙基、叔丁基、叔戊基、叔己基、叔辛基、α ,α - 二烷基苄基或核取代的α ,α - 二烷基苄基;和 R₂ 代表叔丁基、叔戊基、叔己基、叔辛基、α ,α - 二烷基苄基或核取代的α ,α - 二烷基苄基)及其盐在此公开。根据本发明的新型核取代水杨酸及其盐在水中、有机溶剂或有机聚合化合物中具有良好的溶解性,因此,这些化合物非常适合用作杀菌剂、聚合化合物的稳定剂或记录材料的显色剂。
