FIELD: technological processes.
SUBSTANCE: invention provides a method of inhibiting accumulation of aluminosilicate scale in liquor circuit of Bayer process equipment. Method involves adding into stream of aluminosilicate scale inhibiting composition containing one or more molecules based on determined silane, in fluid circulation circuit of liquor. Such scale inhibitors reduce scaling and, thus, increased carrying capacity on fluid, increase period of time during which Bayer process equipment can operate, and reduce need for expensive and hazardous washing of acid Bayer process equipment.
EFFECT: invention provides considerable reduction of total costs for operation of Bayer process.
