摘要： The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.

摘要： 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.
