Two-Step Preparation of Benzylacetone

Original language description

Two-step prepn. of benzylacetone has been investigated using layered double hydroxides (LDHs) as catalysts for aldol condensation of benzaldehyde and acetone and Ni supported catalysts for consecutive hydrogenation of benzylideneacetone. Activity and selectivity of LDHs of various Mg/Al ratios to desired product, benzylideneacetone, have been compared in the liq. phase at 333 K. An aldol condensation yield at 100 % conversion of benzaldehyde was 78 % using catalyst HT-2.0. In the following, optimal hydrogenation conditions-temp. of 353 K, hydrogen pressure of 5 MPa and 5 wt% of catalyst NiSAT 320 were found. At 95 % conversion of benzylideneacetone the selectivity to desired product was 99 %.
