Patent number: 7704406Abstract: 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.Type: GrantFiled: July 29, 2008Date of Patent: April 27, 2010Assignee: BASF AktiengesellschaftInventors: Bernd Wenderoth, Monica Fernandez Gonzalez, Stefan Dambach, Ludwina Machetanz, Uwe Nitzschke

Patent number: 7645394Abstract: The antifreeze of the present invention is including propylene glycol, first material, and second material. The first material is normal aliphatic dicarboxylic acid in which number of carbon atoms is from 10 to 12, salt of the normal aliphatic dicarboxylic acid, or mixture thereof. The second material is benzimidazole compound which has a benzimidazole skeleton, salt of the benzimidazole compound, triazine compound which has a triazine skeleton and has a mercapto group, salt of the triazine compound, or mixture thereof. Such antifreeze has less environment load than antifreeze including ethylene glycol. Furthermore, such antifreeze does not cause metal to corrode more than the antifreeze including ethylene glycol.Type: GrantFiled: December 3, 2004Date of Patent: January 12, 2010Assignees: Honda Motor Co.
