FIELD: chemistry.
SUBSTANCE: invention pertains to water treatment, and particularly to reagents and compositions, used for preventing scaling and corrosion in industrial water circulation systems. The composition contains aminotrimethylenephosphonic acid - 35-45, hydrolysed polymaleic anhydride, containing 70-120 links in the chain, in quantity of 18-22, and water constitutes the rest.
EFFECT: higher efficiency in relation to inhibition of corrosion and scaling, coupled with nontoxicity.
