Corrosion-inhibiting composition based on carboxylic acid and its application for inhibiting corrosion

摘要

Composition based on carboxylic acid for inhibiting corrosion and the application of the said composition for inhibiting corrosion, inter alia in refrigeration systems and more particularly in refrigeration systems with water circulation. The said composition, based on carboxylic acids or their derivatives, is characterised in that heptanoic acid or its derivatives represent at least 20 % by weight, calculated relative to the acid form, of the said carboxylic acids.
