Abstract
The object of the invention is to specify a process with which both Cand Caldehydes can be produced economically. Here, the process should be able to to be supplied with the lowest possible dependence on raw material suppliers and also should be able to react flexibly to fluctuations in demand with respect to Cand Caldehydes. The use of resources should also be optimized. The process proposed uses LPG or NGL as raw material. The process according to the invention essentially differs from known LPG-based processes in that the intermediate obtained, after dehydrogenation and removal of by-products, is divided into two portions. C9 aldehyde is produced from the first portion by oligomerization and hydroformylation while C5 aldehyde is obtained by hydroformylation of the second portion. This has the critical advantage that it is possible to divide the intermediate flexibly into the two portions so that either more Cor more Caldehydes can be produced depending on the respective demand.
