Abstract
Process for the production of a piperazine salt comprising preparing the salt of 1,1 "-methylene-bis (2-hydroxynaphthalene-3-carboxylic acid) of np-chlorobenzhydryl-n" - (2-hydroxyethoxyethyl) piperazine in wherein the acid and base components are present in an equimolar ratio, by contacting a diacid salt of np-chlorobenzhydryl-n "- (2-hydroxyethoxyethyl) piperazine, in an aqueous solvent, with an equimolar amount of a dibasic salt of a 1,1 "-methylene-bis (2-hydroxynaphthalene-3-carboxylic acid).
