    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.

    Abstract translation: 至于二醇或二醇醚,其在处理温度下使用的耐热性添加剂时在氧气的基本上排除至约220℃,有机膦酸酯或亚磷酸的酯,优选地采用Hydroxyphosphono羧酸发生。 所述添加剂用作抗衰老剂。 由有机膦酸盐,或phoshorigen酸的酯和甘油与空间位中的至少一个酯的添加剂受阻线性羧酸羟基的。 一种替代添加剂包括位阻羟基苯基的化合物,有机膦酸酯或亚磷酸的酯和芳族胺类抗氧化剂。 该添加剂还可以包含聚羧酸和叔烷醇胺。 优选的添加剂含有溶解在三甘醇:约1-5重量%Hydroxyphosphono羧酸,0.01-2重量受阻酚 - 亚烷基羧酸混合酯的%,0.01-2重量%的 苯乙烯化的N-苯基苯胺,5-15重量叔烷醇胺的%和2.5-5重量%的6,6“ 6' ” - (1,3,5-三嗪-2,4,6-三triyltriimino )-trihexansäure。
