Procedure

The procedure of example 2 is repeated, i.e. 1125 kg/h of aldehyde are introduced and the total amount of 220 kg/h of O2 is introduced in the first stage, but 3-methylbutanal is used instead of valeraldehyde. The 3-methylbutanal is obtained by hydroformylation of isobutene and purified by distillation. It comprises at least 99% by weight of 3-methylbutanal. For the start-up, the reactor is filled with 3-methylbutyric acid rather than with valeric acid.
