摘要： A process for producing biodiesel from fats, oils or split fatty acids containing steryl glycosides, wherein the fats, oils or split fatty acids are reacted with short-chain alkanols in the presence of a catalyst by transesterification or esterification to a fatty acid alkyl ester to obtain a first product stream, includes washing the first product stream with water in a washing device, so as to form a suspension layer on a phase boundary layer between a heavy phase rich in water and the first light phase rich in the fatty acid alkyl ester. The suspension layer is treated by introducing kinetic energy. A second product stream is withdrawn from the first light phase and intensively mixed with water to obtain a third product stream. A mechanical separation is performed on the third product stream to provide a fourth product stream and a fifth product stream. The fifth product stream is withdrawn as a heavy phase that is enriched in the steryl glycosides. A product conditioning is performed on the fourth product stream to obtain on-spec biodiesel.

摘要： A method is described for the manufacture of polyesters of aromatic dicarboxylic acids with aliphatic and/or cycloaliphatic dials, in which an aromatic dicarboxylic acid in the presence of a monocarboxylic acid or a mixture of a monocarboxylic acid present in a saturated solution with water or another suitable solvent is converted with an aliphatic or cycloaliphatic dial to a dicarboxylic acid alkanediolestercarboxylate and/or its oligomers, which are polycondensed in further process steps to the polyester.
摘要翻译：描述了用脂族和/或脂环族表盘制备芳族二羧酸的聚酯的方法，其中芳族二羧酸在一元羧酸或饱和溶液中存在的单羧酸与水或其它物质的混合物存在下合适的溶剂用脂族或脂环族表盘转化成二羧酸烷二醇酯羧酸酯和/或其低聚物，其在进一步的方法步骤中缩聚成聚酯。

摘要： Process of producing polytrimethylene terephthalate (PTT) by esterification of terephthalic acid (TPA) with trimethylene glycol (TMG) in the presence of a catalytic titanium compound, precondensation and polycondensation. The esterification is effected in at least two stages, where in the first stage a molar ratio of TMG to TPA of 1.15 to 2.5, a content of titanium of 0 to 40 ppm, a temperature of 240 to 275° C., and a pressure of 1 to 3.5 bar are used. In the at least one subsequent stage a content of titanium is adjusted which is higher than in the initial stage by 35 to 110 ppm.
