The present invention relates to animproved process for making alcoholnisopropyl ester, by the catalytic hydrogenation of acetone,napplicable on existing plants and catalystsncommercial, classical, nickel - typenalumina. The process by using a hydrogenndry and demulsified and of a thermal level belown180 ° C, avoids secondary dehydration reactions,nincreases the performance of the catalyst by prolonging itnlife at over 10000 hours of continuous operation,nnickel catalysts being non-regenerative. |
