PROCESS FOR PREPARING WATER-BINDING AGENT OF DISPERSIVE ALUMOSILICATE SYSTEMS Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: synthesis of a new water-binding agent of an unspecified structure of dispersive alumosilicate systems such as a coordinated ferric chloride compound with a mixture of saturated (fatty) primary amines of the general formula: RNH₂ wherein R is -C₁₇-C₂₀-alkyl having properties better than those of the prior art water- binding agents. The process is carried out by treating ferric chloride with a molten mixture of saturated (fatty) primary amines of the general formula: RNH₂ wherein R is -C₁₇-C₂₀, at a ferric chloride to fatty amines molar ratio of 2.1-2.3 (1.0-1.2). EFFECT: improved properties of water-binding agents. 1 dwg, 3 tbl
