METHOD OF PREPARING ALUMINIUM HYDROXIDE OF PSEUDO-BOEHMITE STRUCTURE Russian patent published in 1995 - IPC

Abstract SU 1490873 A1

FIELD: chemical industry. SUBSTANCE: aluminium is subjected for electroerosion dispersing in water with carbon dioxide feeding to it. Carbon dioxide is added at the dose 0.3-1.6 kg per 1 kg dispersed aluminium, and products of erosion were boiled. Proposed method ensures to decrease the content of baierite and metal in aluminium hydroxide and carriers and catalysts can be made of its. EFFECT: enhanced purity of product. 2 cl, 1 tbl
