Disclosed herein are compositions comprising organic anhydrides having a reduced tendency to discolor with time, even when held at elevated temperatures for extended times. The compositions are produced by mixing at least one acid halide and various derivatives of hydroxy carboxylic acids with an anhydride to form a homogenous solution. Also disclosed is a process for preparing the compositions.
本文所公开的是由有机酸酐组成的组合物,即使在高温下长时间保存,其随时间变色的趋势也会降低。这些组合物是通过将至少一种酸卤化物和羟基
羧酸的各种衍
生物与酸酐混合形成均质溶液而制得的。此外,还公开了制备这些组合物的工艺。
