Abstract
Diacetoxybutane is prepared by a process for hydrogenating diacetoxybutene in the presence of a supported hydrogenation catalyst comprising catalytically reacting diacetoxybutene with hydrogen continuously in an insulation reaction apparatus utilizing a fixed-bed of said hydrogenation catalyst, withdrawing the reaction effluent continuously from said reaction apparatus, circulating at least a part of said reaction effluent to said reaction apparatus while controlling the temperature of influx of said reaction apparatus at a temperature lower than the temperature of efflux from said reaction apparatus by 5.degree. to 100.degree. C.
