Abstract

g -Butyrolactone is produced by the catalytic dehydrogenation of butandiol-1,4 at a temperature in the range 200-300 DEG C. in the presence of hydrogen and a catalyst containing 10-40% by weight of copper, 20-60% of zinc oxide and 20-60% of aluminium oxide.ALSO:A catalyst for the dehydrogenation of butanediol-1,4 comprises 10-40% by weight of copper, 20-60% of zinc oxide and 20-60% of p aluminium oxide. The catalyst is preferably prepared by mixing dried aluminium oxide/hydroxide with zinc oxide, kneading with copper nitrate and drying, then heating to 400-550 DEG C. in a current of air, forming into catalyst bodies and heating in a current of hydrogen.
