Abstract
658,531. Anti-freeze compositions. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ March 2, 1949, No. 5644. Convention date, March 19, 1948. [Class 29] An anti-freeze composition comprises thylene glycol and a hexylene glycol free from terminal hydroxyl groups. 'The hexylene glycols preferably have a tertiary carbon atom to which is attached a hydroxyl group and/or have the two hydroxyl groups attached to carbon atoms separated by at least a third carbon atom, and 2-methyl-2, 4-pentanediol, 2-methyl-2, 3-pentanediol, 2-methyl-3, 4-pentanediol, 2, 4-hexanediol, 2, 5-hexanediol, 3-methyl-2, 4-pentanediol and 3-methyl-3, 4-pentanediol are specified. An aqueous solution containing 5 to 30 mol. per cent of the cylcols is preferably used, and the ratio of the glycols may vary from about 20-90 per cent by weight of ethylene gylcol to about 80- 10 per cent by weight of the hexylene glycol. Specific examples are given. Antifoaming agents such as kerosene, alkyl or dialkyl phthalates such as normal or secondary dibutyl phthalate, anticorrosion agents such as sodium nitrite or a nitrite salt of a secondary amine, such as dicyclohexylamine nitrite, buffer materials such as barium hydroxide and di- or tri-ethanelamine and dyes, may also be added to the composition.
