| titleOfInvention | A kind of preparation method of acetic ester hydrogenation catalyst |
| abstract | The invention discloses a kind of preparation method of acetic ester hydrogenation catalyst, comprise successively: (1) prepares silicon source solution, copper source solution or containing the precursor of Cu and the copper source of the precursor of catalyst aid M and the mixed solution in M source; (2) in a heated condition, the mixed solution in copper source solution or copper source and M source is added drop-wise in the solution of silicon source, regulates pH value simultaneously, produce sediment with making dissolution homogeneity, thus, obtain catalyst precarsor gel; (3) in a heated condition, carry out aging to gel, (4) wash aging gel, filter and drying; (5) gel of roasting drying, thus obtain described catalyst, wherein, in step (1), silicon source solution contains urea, and the mixed solution in copper source solution or copper source and M source contains ammonium salt; In step (2), by dripping alkali lye or adjusting urea and/or ammonium salt consumption adjustment pH value in advance. |
