Abstract

1512414 Butane-1,4-diol HOECHST AG 21 July 1975 [20 July 1974] 30448/75 Heading C2C Butane-1,4-diol is obtained by catalytically reacting but - 2 - ene - 1,4 - diol diacetate (I), but - 2 - ene - 1,4 - diol monoacetate (II), butane-1,4-diol diacetate (III) or butane-1,4- diol monoacetate IV, or a mixture of two or more thereof, with hydrogen. The catalyst is for example copper-chromium oxide to which may be added as promoter thorium or an element from Groups IVa, Va, VIa, VIIa or VIII of the Periodic Table. In the examples, copper chromium oxide was used with Mu, Re, Mo, V and Th as promoter; rhenium or rhodium on active carbon was also used mixed with the copper chromium oxide catalyst. When using I as starting material II, III and IV may be obtained as intermediates which need not be separated. Temperatures of 100-300‹ C. and pressures of 50-400 bars are suitable.
