Conclusions
-
1.
On the zeolites NaY, KNaY, HNaY and NdNaY, at 150–250°, butyraldehyde undergoes mainly the crotonic condensation with the formation of 2-ethylhexenal. The most active catalyst is KNaY, the most stable is NaY, and the least selective are HNaY and NdNaY.
-
2.
Butanol, 2-ethyl-1-hexanol, 2-ethylhexanal, and 2-ethylhexenal are obtained in the presence of 4% Ni/NaY in a hydrogen atmosphere, the ratio in the yields of which changes during the course of catalyst operation.
