Abstract
Inventia se refera la un procedeu de obtinere si purificare a acizilor fenilen - bis - oxi -bis-acetic, cu formula generala I : pe baza reactiei izomerilor dihidroxibenzenului (adica pirocatechina, rezorcina si hidrochinona), cu acidul monocloracetic în solutii apoase si în prezenta hidroxizilor alcalini.The invention relates to a process for obtaining and purifying phenylene-bis-oxybis-acetic acids of the general formula I: based on the reaction of the dihydroxybenzene isomers (i.e. pyrocatechin, resorcinol and hydroquinone) with the monochloroacetic acid in aqueous solutions and in the presence of the alkali hydroxides.
