摘要： The invention relates to a process for the preparation of polyvalent alcohols by hydrogenation of an aldehyde. According to the invention said aldehyde is obtained by aldolisation reaction of an aldehyde containing an alpha hydrogen atom and having the formula R1CHO, or the mixture of said aldehyde with a second different aldehyde having the formula or R2CHO, wherein R1 is selected from alkyl having 1-12 carbon atoms, cycloalkyl, aryl and aralkyl having 1-14 carbon atoms, and R2 is selected from H, alkyl having 1-12 carbon atoms, cycloalkyl, aryl and aralkyl having 1-14 carbon atoms, said aldolisation being carried out in the presence of a weak base anion exchange resin, and the hydrogenation being carried out in the presence of a solvent and a hydrogenation catalyst.

摘要： The invention concerns a process for separating 2-butyl-2-ethyl-1,3-propanediol from a reaction blend, which has an organic phase containing BEPD, and an aqueous phase, and which has been produced by allowing 2-ethylhexanal and formaldehyde to react in a reactor in the presence of a hydroxide compound, whereby the hydroxide compound has been fed into the reactor principally during the whole time of reaction. A characterizing feature of the invention comprises allowing the reaction blend to phase into an organic phase and an aqueous phase and removing the aqueous phase immediately from the reactor, i.e. within ca. 0.1 minute to 2 hours from the completion of the input of the hydroxide compound. The organic phase is washed with an aqueous solution to remove impurities and BEPD is recovered by submitting the water washed organic phase to distillation. By the invention the number of process steps is reduced, and the raw material costs decrease, because the usual addition of sulphuric acid is not needed.
摘要翻译：本发明涉及从具有含有BEPD的有机相和水相的反应共混物中分离出2-丁基-2-乙基-1,3-丙二醇的方法，并且其通过使2-乙基己醛和甲醛在氢氧化物存在下在反应器中反应，由此氢化物化合物主要在反应的整个时间内进料到反应器中。本发明的特征特征包括使反应混合物相进入有机相和水相，并立即从反应器中除去水相，即在约从氢氧化合物的输入完成0.1分钟至2小时。有机相用水溶液洗涤以除去杂质，通过将水洗的有机相送入蒸馏来回收BEPD。通过本发明，减少了工艺步骤的数量，并且原料成本降低，因为不需要通常加入硫酸。
