Abstract: The present invention describes novel coolant concentrates and the production and use thereof.

Abstract: The present invention refers to a vapor space anticorrosive composition comprising corrosion inhibitors, surfactants and possibly thickeners, wherein one surfactant is selected from alkylamine ethoxylates, and being useful as an engine run-in composition and as a coolant.

Abstract: Antifreeze concentrate with corrosion protection which is suitable for coolants and heat transfer fluids and comprises freezing point-lowering liquids and also particular sulfur-comprising organic compounds, inorganic molybdate salts, inorganic phosphate salts and aliphatic, cycloaliphatic or aromatic monocarboxylic, dicarboxylic or tricarboxylic acids as corrosion inhibitors. Aqueous coolant compositions which are suitable for cooling an internal combustion engine whose cooling apparatus has been made of aluminum using a soldering process using a fluoroaluminate flux can be obtained therefrom.

Abstract: Corrosion protection formulation comprising (A) from 0.01 to 5% by weight of alkylamine ethoxylates as surfactant component, (B) from 0.01 to 10% by weight of corrosion inhibitors, (C) from 0 to 0.3% by weight of thickeners, (D) from 5 to <75% by weight of freezing point-lowering alcohols selected from among alkanols, glycols, polyalkylene glycols and glycerol, (E) from 5 to 90% by weight of vegetable and/or fatty oils, (F) from 0 to 5% by weight of water and (G) from 0 to 5% by weight of conventional emulsifiers. The formulation is particularly suitable for protecting zinc or zinc-plated components or surfaces or cadmium or cadmium-plated metallic surfaces against corrosion caused by runway deicing compositions used at airports.

Abstract: The present invention relates to an aqueous antifreeze composition comprising 10 to 50% by weight of one or more dicarboxylic acids, preferably aliphatic dicarboxylic acids having 4 to 12 carbon atoms in the form of the alkali metal, ammonium or alkaline earth metal salt. Preferably, these salts are used in combination with at least one further substance. This gives antifreeze compositions with a good frost protective action, good heat conductivity and good protection against corrosion.
