| titleOfInvention | Anti-aging agent for glycols or glycol ethers |
| abstract | An organic phosphonate or an ester of a phosphoric acid, preferably a hydroxyphosphono carboxylic acid, is used as temperature-resistant additive for a glycol or a glycol ether, which is in turn used in a process excluding oxygen to a large extent and reaching temperatures of up to approximately 220 DEG C. The additive serves as anti-aging agent. An additive consists of an organic phosphonate or an ester of a phosphoric acid and a glycerin ester with at least one linear carboxylic acid containing a sterically hindered hydroxyphenyl group. An alternative additive contains a compound having a sterically hindered hydroxyphenyl group, an organic phosphonate or an ester of a phosphoric acid and an aromatic aminic antioxidant agent. Said additive can also contain a polycarboxylic acid and a tertiary alkanolamine. A preferred additive contains, dissolved in triethylene glycol: approximately 1-5 % by weight of hydroxy-phosphono-carboxylic acid; 0.01-2 % by weight of a sterically hindered phenol-alkylene-carboxylic acid mixed ester; 0.01-2 % by weight styronated N-phenylbenzolamine; 5-15 % by weight of a tertiary alkanolamine and 2.5-5 % by weight 6,6',6''-(1,3,5,-triazine-2,4,6-triyltriimino)-trihexanoic acid. |
