    Abstract: The present invention relates to two processes for providing stable liquid blends of a) pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, b) octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and c) tris-(2,4-di-tert-butylphenyl)phosphite. The first process comprises preparing a solid mixture comprising about 2 parts to about 3 parts by weight a), about 2 parts to about 3 parts by weight b) and about 2 parts to about 12 parts by weight c), heating the mixture to 185° C. or higher for a sufficient time to obtain a clear liquid blend of a), b) and c), cooling the liquid blend to a temperature of from 90° C. to 140° C. and maintaining the liquid blend at a temperature of from 90° C. to 140° C. The second process comprises preparing a solid mixture comprising about 2 parts to about 3 parts by weight a) and about 2 parts to about 3 parts by weight b), heating the mixture to 90° C. or higher for a sufficient time to obtain a clear liquid mixture of a) and b), adding about 2 parts to about 12 parts by weight c) thereto to obtain a clear liquid blend of a), b) and c) and maintaining the liquid blend at a temperature of from 90° C. to 140° C. The liquid blends of a), b) and c) are stable at the temperature at which they are maintained for greater than 120 hours.

    Abstract translation: 本发明涉及用于提供稳定的液体混合物的两种方法，其中a）季戊四醇四（3-（3,5-二 - 叔丁基-4-羟基苯基）丙酸酯，b）3-（3,5-二叔丁基 丁基-4-羟基苯基）丙酸酯和c）三 - （2,4-二叔丁基苯基）亚磷酸酯。 第一种方法包括制备固体混合物，其包含约2重量份至约3重量份的a），约2重量份至约3重量份的b）和约2重量份至约12重量份的c），将混合物加热至185 ℃或更高一段时间以获得a），b）和c）的澄清液体共混物，将液体共混物冷却至90℃至140℃的温度，并将液体共混物保持在 温度为90℃至140℃。第二种方法包括制备固体混合物，其包含约2重量份至约3重量份的a）和约2重量份至约3重量份的b），将混合物加热至90℃ ℃或更高，以获得a）和b）的澄清液体混合物，加入约2份至约12份（重量）的c），得到a），b）和c）的澄清液体共混物， 并将液体共混物保持在90℃至140℃的温度.a），b）和c）的液体共混物在其a 维持时间超过120小时。
