4-Hydroxybenzaldehyde → 4-Hydroxybenzyl Alcohol

Participants

Reaction Steps

A 1.0 g quantity of the catalyst (CuO/ZnO/Aluminium oxide) in 50 ml methanol was placed in a 300 ml capacity Parr reactor. The contents were treated with hydrogen at 170° C., under pressure of 400-500 psig for 2-3 hrs. Cooled to room temperature, depressurized, followed by the addition of 10.0 g of 4-hydroxybenzaldehyde, in 50 ml of methanol. Hydrogenation was carried out at 170° C., under a pressure of 400-500 psig, for 2-3 hrs. The conversion of benzaldehyde was 100% providing 100% selectivity of 4-hydroxybenzyl alcohol, the desired alcohol product.
