The invention relates to a process for the production of 1,6-difunctionalized hexane derivatives from 1,3-diunsaturated hydrocarbons, preferably butadiene, wherein a hydroformylation with carbon monoxide and hydrogen is performed in the presence of an at least dihydric alkanol and during the hydroformylation the temperature is increased. The reaction yields the acetals of the 1,6-hexanedial derivatives which are isolated and further reacted to obtain the desired 1,6-difunctionalized hexane derivatives, in particular 1,6-hexanediamine, 1,6-hexanediol and adipic acid.
本发明涉及一种从 1,3-二不饱和碳氢化合物(最好是丁二烯)生产 1,6-二官能化己烷衍生物的工艺,其中在至少有二元烷醇存在的情况下,用一氧化碳和氢进行加氢甲酰化,在加氢甲酰化过程中温度升高。反应生成 1,6-己二醛衍生物的乙缩醛,将其分离出来并进一步反应,可得到所需的 1,6-二官能化己烷衍生物,特别是 1,6-己二胺、1,6-己二醇和己二酸。
