Abstract
The invention relates to compounds having the general formula <FORM:0971672/C1/1> wherein R is a divalent hydrocarbon radical containing from 1 to 12 carbon atoms and wherein R1 is taken from the group consisting of hydrogen and alkyl radicals containing from 1 to 3 carbon atoms and wherein the hydroxy groups are positioned other than o-. Compounds claimed per se are N,N-trimethylene-bis (p-hydroxybenzamide), N,N-trimethylene-bis (m-hydroxybenzamide), N,N-tetramethylene-bis (p-hydroxybenzamide), N,N-tetramethylene-bis (m-hydroxybenzamide), N,N-pentamethylene-bis (p-hydroxybenzamide), N,N-pentamethylene-bis (m-hydroxybenzamide), N,N-hexamethylene-bis (p-hydroxybenzamide), N,N-hexamethylene-bis (m-hydroxybenzamide), N,N-heptamethylene-bis (p-hydroxybenzamide), N,N-octamethylene-bis (p-hydroxybenzamide), N,N-nonamethylene-bis (p-hydroxybenzamide), N,N-decamethylene-bis (p-hydroxybenzamide), N,N-phenylene-bis (m-hydroxybenzamide). The compounds are prepared by reacting two parts of a hydroxybenzoic ester of the general formula <FORM:0971672/C1/2> wherein R is hydrocarbon radical containing from 1-12 carbon atoms e.g. methyl or ethyl meta or para hydroxy benzoate, propyl meta or parahydroxy benzoate, phenyl meta or para hydroxy-benzoate, methoxy phenyl meta or parahydroxy benzoate, 4,41-biphenyl-p-hydroxy-benzoate, with one part of a diamine of the general formula <FORM:0971672/C1/3> wherein R is a divalent hydrocarbon radical containing from 1 to 12 carbon atoms and R1 is hydrogen, an alkyl radical containing from 1 to 3 carbon atoms or an aryl radical containing from 6 to 12 carbon atoms e.g. ethylene diamine, trimethylene diamine, tetramethylene diamine, pentamethylene diamine, hexamethylene diamine, heptamethylene diamine, octamethylene diamine, decamethylene diamine, m- and p-phenylene diamine, secondary diamines such as N,N1-dimethylhexamethylenediamine, at a temperature of from 60 to 200 DEG C. and continuing the reaction until a high yield of product is obtained. In an example methyl p-hydroxybenzoate is reacted with hexamethylene diamine to produce N,N-hexamethylene-bis (p-hydroxybenzamide).
