    摘要： The invention relates to a method for producing carboxylic esters by converting a carboxylic acid or a carboxylic acid anhydride or a mixture thereof with an alcohol in a reaction system comprising one or more reactors, wherein reaction water is distilled as alcohol-water-azeotrope with the vapors, the vapors are at least partially condensed, the condensate is separated into an aqueous phase and an organic phase and said organic phase is supplied at least partially back into said reaction system. Components boiling lower than the alcohol are at least partially removed from said returned organic phase such as wherein components boiling lower than alcohol are evaporated and/or distilled off. An enrichment in the reaction system of by-products boiling lower than alcohol is avoided. Alcohol losses can be minimized by discharge currents.

    摘要翻译： 本发明涉及一种通过在包含一个或多个反应器的反应体系中将羧酸或羧酸酐或其混合物与醇反应来制备羧酸酯的方法，其中将反应水作为醇 - 水 - 共沸物与 蒸气，蒸气至少部分冷凝，将冷凝物分离成水相和有机相，并将所述有机相至少部分地供给至所述反应体系。 沸点低于醇的组分至少部分地从所述返回的有机相中除去，例如其中沸点低于醇的组分蒸发和/或蒸馏掉。 避免了沸点低于酒精的副产物的反应体系的富集。 酒精损失可以通过放电电流最小化。

    摘要： The present invention relates to polymers comprising benzotriazole containing repeating units. Optical devices, comprising the polymers of the present invention, can show significant advantages in color purity, device efficiency and/or operational lifetime. In addition, the polymers can have good solubility characteristics and relatively high glass transition temperatures, which facilitates their fabrication into coatings and films that are relatively thin, thermally stable, and relatively free of defects.
