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. In contrast to Example 2, the reactor used was a DN15 tube (internal diameter 17.3 mm) not of length 3 m but of length 4 m, with a total volume of 9.1 l. In this example too, about 50% of the total volume of the tubular reactor was filled with static mixers with a hydraulic diameter of 2 mm and a relative void volume of 0.80.
