Organic aluminum sol and preparation method thereof

Abstract

An organic aluminum sol and a preparation method thereof related to chemical technology fields. Organic mixed acids are used to react with aluminum powder to prepare organic aluminum sol as a precursor for preparing alumina fiber. The aluminum powder, formic acid, and oxalic acid are used as raw materials, the oxalic acid and the formic acid are firstly mixed to be even according to a preset ratio to obtain a mixed acid solution, and the aluminum powder is then completely reacted with the mixed acid solution to obtain an aluminum carboxylate solution under a condensation reflux condition, and the aluminum carboxylate solution is finally filtered to obtain the aluminum carboxylate sol that is clear and transparent. A chemical formula of a composition of the organic aluminum sol is expressed as: Al(OH)x(HCOO)y(COO—COO)z, wherein 0<x<2, 0<y<2, and 0<z<1.
