摘要： A process for producing esters comprises esterifying an acid or anhydride with an excess of an alcohol to produce a crude ester, recovering excess alcohol from the crude ester and recycling recovered excess alcohol to the esterification reaction together with fresh alcohol. The process is improved by controlling the ratio of the amount of recycled alcohol and the amount of fresh alcohol in dependence on the level of impurities in the recycle alcohol. Further improvements come from feed forwarding fresh alcohol analysis results and from preheating the alcohol before loading into the reactor. Preferably, ester product quality is improved by stripping the alcohol for oxygen removal prior to esterification.
摘要翻译：一种生产酯的方法包括用过量的醇酯化酸或酸酐以产生粗酯，从粗酯中回收过量的醇，并将回收过的醇与新鲜醇一起循环回到酯化反应中。通过根据再循环酒精中的杂质含量控制再循环醇的量与新鲜醇的量的比例来改进该方法。进一步的改进来自饲料转运新鲜酒精分析结果，并且在装入反应器之前预热酒精。优选地，在酯化之前通过汽提醇去除氧而提高酯产品质量。

摘要： The efficiency of catalyzed batch esterification reactions is improved by the use of a particular temperature and pressure profile during the reaction cycle. In particular elevated pressure is maintained to prevent alcohol boil off during initial mixing and reaction of the reactants prior to any catalyst addition, and preferably the pressure is reduced rapidly after the desired reaction temperature has been reached.

摘要： Esters produced by the catalyzed reaction of alcohols and acids or anhydrides are neutralized by treatment with an aqueous alkaline alkali metal salt solution in an amount that provides less than a stoichiometric amount of alkali metal salt in relation to the acidity of the crude ester and the amount of water present during the treatment is from 0.8 to 1.4 wt % of water based on the weight of crude ester. When using titanium as the esterification catalyst, the ester resulting from this process contains less than 0.01 ppm by weight of titanium residue, so that it is storage stable when stored in the presence of an antioxidant.

摘要： A process for the catalytic or non-catalytic esterification of acids or anhydrides with a mono-alcohol or a polyhydroxy compound which comprises the steps of adding the reagents to a reaction vessel to form a reaction mixture, and heating the reaction mixture and maintaining a pressure sufficient to obtain boiling of the reaction mixture thereby causing esterification and removing water as vapor while continuously mixing the reaction mixture in the reactor vessel such that at least about 2.5 to about 20 volumes of reaction mixture are internally recirculated per minute, whereby the rate of conversion is enhanced.
