Corrosion inhibitor combinations and process for inhibiting corrosion in heat transfer fluids.

摘要

Solutions of potassium, aliphatic monocarboxylate, hydrocarbyl dicarboxylate and hydrocarbyl triazole, with one or more silicate, phosphate, borate, or nitrate, have superior compatibility and anticorrosion properties, useful in heat transfer fluids, antifreezes and metal corrosion inhibition.
