2-Hydroxydodecylmonoesters of dicarboxylic acids, their salts and their use as corrosion inhibitors in aqueous systems

摘要

Mono-2-(hydroxydodecyl) dicarboxylates of the general formula (I) …IMAGE… and salts thereof of the general formula (II) …IMAGE… …??in which A represents the radicals -(CH2)2-, -(CH2)3-, …IMAGE… and M represents an alkali metal or the ammonium group, and the use of compounds of this type alone or in combination with one or more complexing agents in concentrations from 1 to 100 ppm as corrosion inhibitors in aqueous systems, if appropriate in the presence of further scale prevention agents and/or dispersants and/or nonferrous metal inhibitors and/or microbicides which are known per se.
