  Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes. Higher temperatures and/or longer residence times and/or higher partial pressure of carbon monoxide than in conventional processes are used to ensure hydroformylation of all the monomers.

  The present invention relates to a method for producing at least one decanol by means of hydrogenating at least one decenal, wherein a first hydrogenation is carried out in the liquid phase on a solid first catalyst, wherein the first catalyst contains copper and nickel. The aim of the invention is to provide a method of the type mentioned above, according to which decenals can be hydrogenated into decanols in high yields even after long operating periods. The content of non-reacted decenals in the hydrogenation discharge in particular should be less than 1500 ppm. Said aim is achieved by carrying out the hydrogenation in two steps, which is to say in a first step in a known manner using a catalyst comprising copper, nickel and optionally chromium and/or barium oxide, and subsequently in a second step using a different catalyst that must be free of copper, chromium and nickel.

  本发明涉及一种通过氢化至少一种己烯醛来生产至少一种癸醇的方法，其中在固体第一催化剂上在液相中进行第一次氢化，其中第一催化剂含有铜和镍。本发明的目的是提供一种上述类型的方法，根据该方法，即使在长时间运行后，己烯醛也可以高产率地氢化为癸醇。特别是，氢化废液中未反应的己烯醛的含量应小于1500 ppm。通过在两个步骤中进行氢化来实现上述目的，即在第一步中使用包含铜，镍和可选的铬和/或钡氧化物的催化剂进行已知的方式，然后在第二步中使用必须不含铜，铬和镍的不同催化剂。
