1. a kind of organic acid processing method of aluminium isopropoxide dead catalyst, with the mistake generated in unsaturated aldehyde ketone reduction production processThe mix products of living aluminium isopropoxide and by-product are process object, it is characterized in that, include the following steps:

  • (1) under stirring,Mix products are added in organic acid soln, temperature is raised slowly to stop stirring after temperature is stablized, and mixed liquor is delivered to pointLayer device stratification;

    (2) lower layer'"'"'s water phase after being layered is delivered to precipitation tank, 60-100 DEG C is heated in precipitation tank, and maintainStop heating after temperature 5-60min, obtains the liquid containing flocky precipitate;

    It (3) will be defeated after the liquid extraction containing flocky precipitateIt send to press filteration system and carries out filters pressing processing, obtained solid is boehmite, and gained liquids recovery is used for organic acid soln.
