Dicarboxylic acid mono-(2-hydroxydodecyl)-esters, their salts and their use as corrosion inhibitors in aqueous systems

摘要

Dicarboxylic acid mono-(2-hydroxydodecyl)-esters corresponding to the following general formula <IMAGE> (I) and salts thereof corresponding to the following general formula <IMAGE> (II) wherein A represents the radicals <IMAGE> and M represents an alkali metal or ammonium, the use of these compounds as corrosion inhibitors in aqueous systems either by themselves or in combination with one or more complexing agents in concentrations of from 1 to 100 ppm, optionally in the presence of other scale inhibitors, dispersants, non-ferrous metal inhibitors, and/or microbicides.
