A kind of inorganic acid treatment method and device of aluminum isopropoxide waste catalyst
ActiveCN108793214BSolve processing problemsGuaranteed reuseCatalyst regeneration/reactivationChemical recyclingKetoneAluminium isopropoxide
The invention relates to the field of chemical processes, and particularly discloses an inorganic acid treatment method for an aluminium isopropoxide dead catalyst and a device adopting the method. According to the method, an inorganic acid solution is taken as an acidolysis extraction agent for acidolysis extraction to the aluminium isopropoxide dead catalyst generated during reduction process ofunsaturated aldehyde ketone, so that organic phases and inorganic phases are separated; useful components in the separated organic phases are further recycled, aqueous phase obtained after separation are evaporated and concentrated to obtain an aluminiferous product. According to the invention, the operation is simple, green and environmentally friendly; the treatment problem on the aluminium isopropoxide dead catalyst is solved by adopting a relative gentle method, on the other hand, benefits are increased to a certain extent, and condensate can be used repeatedly.
