FIELD: chemistry. ^ SUBSTANCE: invention relates to materials for preventing or inhibiting scaling on equipment, used in industrial methods having alkaline process streams, and methods of preventing or inhibiting scaling using such materials. disclosed is a composition for reducing aluminosilicate scaling, which contains a polymer which is a product of reaction of a polyalkylene oxide polymer which is epoxide-blocked at the end and an organic compound containing amino functionality and -Si(OR")3 functionality, where R'' is selected from H, a substituted or unsubstituted C1-C20 alkyl, alkenyl, aryl or aralkyl group. Disclosed also is a method of reducing aluminosilicate scaling on equipment using the disclosed composition. The technical result is that when added to an alkaline process stream, the disclosed composition reduces or even completely prevents aluminosilicate scaling on surfaces of equipment such as walls of an evaporating apparatus and heating surfaces. ^ EFFECT: disclosed composition is effective at treatment concentrations which makes it cost effective. ^ 5 cl, 11 tbl, 39 ex |
