摘要 |
FIELD: industrial and waste water treatment. ^ SUBSTANCE: composition contains 10-25% sodium alkylaminophosphonates having general formula: , in which n=9-19, 1-5% sodium chloride, and 70-89% water. Composition is prepared by heat treatment of industrial-grade aliphatic amines with phosphorous acid and formaldehyde. In particular, treatment of aliphatic amines of formula CH3-(CH2)-NH2 (n=9-19) is carried out in presence of hydrochloric acid as catalyst at 95-105°C for 1.5-3.0 h followed by cooling and neutralization with sodium alkali to pH 10. ^ EFFECT: enhanced treatment efficiency. ^ 2 cl, 1 tbl |
