摘要： The disclosure relates to a process for forming an acyloxy carboxylic acid or a derivative of the acid. A hydroxy acid compound is reacted with a carboxylic acid in a reaction vessel and in the presence of a catalyst, such as in a reactive distillation column containing the catalyst. The reaction product formed in the reaction vessel includes an acyloxy carboxylic acid compound, which can be removed continuously from the vessel in a product stream. Another product stream containing unreacted (excess) carboxylic acid and/or reaction byproducts such as water can be separately removed continuously from the reaction vessel.

摘要： A process for producing mixed esters of fatty acids as biofuel or additive to a petroleum fuel for use in a compression ignition (CI) engine. The process preferably provides a partial transesterification of a mixture of fatty acid methyl esters with at least one alkyl alcohol containing 2 to 8 carbon atoms in the presence of a heterogeneous solid acid catalyst to produce a mixture of the fatty acid methyl esters and alkyl alcohol esters of the fatty acids.

摘要： The disclosure relates to methods for separating mixtures of polyols, in particular mixtures of two of more different vicinal diols having close boiling points, thus making them difficult or impossible to separate using conventional distillation techniques. The polyol mixture is reacted with an aldehyde or ketone acetalization agent to form one or more acetals as corresponding acetalization reaction products. The acetalization reaction products are more easily separable either from each other (such as via distillation) or from an unreacted vicinal diol (such as via extraction, settling, or other phase separation). After separation, hydrolysis is performed on the acetalization reaction products to recover the vicinal diols as separate, purified components. The methods provide cost-effective processes for separating different polyols originally formed in admixture.

摘要： An integrated process and system for synthesis of organic-acid esters is provided. The method of synthesizing combines reaction and distillation where an organic acid and alcohol composition are passed through a distillation chamber having a plurality of zones. Side reactors are used for drawing off portions of the composition and then recycling them to the distillation column for further purification. Water is removed from a pre-reactor prior to insertion into the distillation column. An integrated heat integration system is contained within the distillation column for further purification and optimizing efficiency in the obtaining of the final product.
