METHOD OF PROTECTION OF WATER-RETURN SYSTEM FROM CORROSION, SALIFICATION AND BIOOVERGROWING Russian patent published in 1997 - IPC

Abstract RU 2100294 C1

FIELD: organic chemistry. SUBSTANCE: polymeric derivative of hydroxyethylidene diphosphonic acid - hydroxyethylidene diphosphonate polyhexamethylene guanidine of the formula $$$ where n = 10-100 is added to water of return system. Effective inhibition by three indices (corrosion, salification, bioovergrowing) is observed at concentration of this reagent in water 10-20 mg/l. EFFECT: improved method of protection, enhanced effectiveness of agent. 2 cl
