Problems solved by technology

[0002] Aluminum isooctanoate is a thickener widely used in some industrial oils such as grease, thickened benzene, gasoline and turpentine. Currently, aluminum isooctanoate on the market is mainly composed of isooctanoic acid and aluminum sulfate in alkaline conditions (hydrogen Sodium oxide) is obtained through metathesis reaction. During the specific operation, isooctanoic acid is produced first, but isooctanoic acid is often slightly damp in the manufacturing process, which affects the follow-up overall manufacturing purity; meanwhile, aluminum isooctanoate is in the existing There are also the problems of high manufacturing cost and low yield of products in the manufacturing process

Abstract

The invention discloses a preparation method of aluminum iso-octoate. The preparation method comprises the following steps: S1, the outer surface layer of the blocky solid sodium hydroxide is cut offin a dry environment, the cutting-off thickness is 1.5-2.5 mm, and the cut-off surface layer solid sodium hydroxide and the blocky solid sodium hydroxide with the surface layer removed are collected separately. S2; and the blocky solid sodium hydroxide with the surface layer removed is put into a heat conduction grinding machine, the blocky solid sodium hydroxide is ground and crushed through workof the grinding machine, and the ground granular solid sodium hydroxide is screened. The method has the advantages that blocky solid sodium hydroxide is subjected to surface layer cutting, the situation that the subsequent process is influenced due to slight damp is effectively avoided, meanwhile, the cut surface layer sodium hydroxide can be directly prepared into sodium hydroxide for use subsequently, and waste of sodium hydroxide is avoided; meanwhile, the alum solution is used for replacing an aluminum sulfate solution, so that the manufacturing cost of the aluminum isooctanoate can be effectively reduced, and the product yield of the formed aluminum isooctanoate is increased.
