PROCESS FOR THE PURIFICATION OF BUTANE-1,4-DIOL |
摘要 |
<p>The invention provides a process for the purification of a butane-1,4-diol feed containing a minor amount of the cyclic acetal, 2- (4'-hydroxybutoxy)-tetrahydrofuran, which comprises hydrogenating the butane - 1,4-diol feed in a hydrogenation zone in the presence of a minor amount of water and of a hydrogenation catalyst, and recovering from t he hydrogenation zone a butane-1,4-diol product that has a reduced 2-(4'-hydroxybutoxy)-tetrahydrofuran content compared with the butan e- 1,4-diol feed.</p> |
