FIELD: chemistry.
SUBSTANCE: invention relates to polyamines and methods of using said polyamines for scale treatment in different industrial process streams. Disclosed are hydrophobically modified silicon-containing polyamines, containing repeating structural links of two types, a composition based thereon and a method of reducing or eliminating scales in an industrial process, involving addition of the disclosed polymer or composition into a process stream.
EFFECT: disclosed hydrophobically modified silicon-containing polyamines are suitable for aluminosilicate scale treatment in hard-to-clean industrial process streams, such as process streams in a Bayer method of extracting alumina from bauxite, streams of radioactive wastes and effluent streams formed during production of kraft paper.
