Abstract
PURPOSE: To provided the title non-forming low poisonous corrosion inhibitor with a superior anticorrosive effect and superior solubility or dispersibility contg. a reaction product, as an effective component, obtd. by the reaction of a water sol. silicate and a specific polyhydroxycarboxylic acid or its water sol. in the presence of water.
CONSTITUTION: An alkali metal silicate, esp. Na or K silicate is reacted with pref. sodium ortho- or metasilicate and a polyhydroxycarboxylic acid or its water sol. salt of formulaIor II in the presence of water at 20W90°C to obtain a reaction product. The carboxylic acid of formulaIor II includes glyceric acid, glycolic acid and tartaric acid, and its water sol. salt may be, e.g. an alkali metal salt. In the formulae, each of R1, R2 and R3 is H, alkyl or (poly)hydroxyalkylene and M is H or an alkali metal. The total no. of C in the formulae 3W8 and that of OH groups 2W7. This corrosion inhibitor is effectively applied to an aq. soln. of an alkali metal salt or an alkaline earth metal salt used as a liquid refrigerant.
