FIELD: chemical technologies; corrosion inhibitors for low-freezing fluids used as heat-transfer agents in domestic and industrial heat supply systems.
SUBSTANCE: proposed inhibitor contains the following components, mass-%: succinic acid, 3.5-4.5; adipic acid, 7.0-8.0; sodium hydroxide, 7.5-8.5; benzoic acid, 2.5-3.5; water, 35.0-40.0; benzotriazole, 0.25-0.50; sodium bicarbonate, 1.5-2.5; the remainder being glycerin.
EFFECT: enhanced corrosion resistance; avoidance of mineral deposits on the surfaces of items; reduced toxicity of heat-transfer agents.
