METHOD FOR PREPARING ORGANIC-SOLUBLE POLYGUANIDINE SALT AND ORGANIC-SOLUBLE POLYGUANIDINE SALT Russian patent published in 2007 - IPC C08G73/02 A61L2/16 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention describes a method for synthesis of organic-soluble polyguanidine salt. Method involves preparing polyguanidine base by the alkaline dehydrochlorination reaction of polyguanidine hydrophilic salt followed by neutralization of polyguanidine base with hydrophobic organic acid. As hydrophobic organic acid pelargonic, benzoic or undecylenic acid are used, and polyhexamethylene guanidine hydrochloride or poly-(4.9-dioxadodecane guanidine) hydrochloride are used as polyguanidine hydrophilic salt. Also, invention describes polyguanidine organic-soluble salt possessing biocide and hydrophobic properties of the following structural formula: wherein n = 5-70; R means ˜(CH₂)₆˜, ˜(CH₂)₃O(CH₂)₄O(CH₂)₃˜; R₁ means CH₃(CH₂)₄CH=CH(CH₂)₄˜, ˜CH₃(CH₂)₇˜.

EFFECT: improved method of synthesis.
