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.
混合的丁烯流含有丁烯-1和异丁烯,可选地还包括丁烯-2,在水合甲醛化条件下,将所有单体水合甲醛化,产生戊醛混合物。使用比传统工艺中更高的温度和/或较长的停留时间和/或较高的一氧化碳分压,以确保所有单体的水合甲醛化。
