ABSTRACT:
There is disclosed a process for producing diacetoxybutane diol by hydrogenating diacetoxybutene in the presence of a hydrogenation catalyst in which the hydrogenation is carried out in two stages within predetermined temperature ranges, the temperature of the second stage is higher than that of first thereby obtaining the product in high selectivity with high conversion, and a process for producing butanediol by hydrolyzing the diacetoxybutane thus obtained in the presence of a solid acid catalyst.
