Versuchsvorschrift
This example describes the process according to the invention for the aldol condensation of n-pentanal (n-valeraldehyde) to 2-propylheptenal (1+1 product), and the co-aldolization of n-pentanal with 2-methylbutanal to give the cross-product (1+2 product), 2-propyl-4-methylhexenal. The reactor used was, as in Example 3, a DN15 tube (internal diameter 17.3 mm) of length 4 m with a total volume of 9.11. About 50% of the total volume of the tubular reactor was filled with static mixers. In contrast to Example 3, the C5-aldehyde mixture reactant was not fed in upstream of the reactor, but instead into the NaOH circulation system upstream of the circulation pump according to FIG. 2.
