1-氨基乙叉1,1-二膦酸的合成及其阻垢和缓蚀性能
摘要:
有机多膦酸是一类多齿配体的螯合剂,能与许多金属离子形成稳定的配合物[1],70年代国内合成了1-羟基乙叉1,1-二膦酸(HEDP),并已应用于水质稳定,金属缓蚀和无氰电镀[2]。

SYNTHESIS OF 1-AMINO-ETHYLIDENEDIPHOSPHONIC ACID(AEDP) AND ITS PERFORMANCE AS SCALE AND CORROSION INHIBITIOR
Abstract:
Using urea,acetic acid and phosphorus trichloride as raw materials,ammonium salt of 1-aminocthylidenediphosphonic acid(NH,AEDP) has been synthesized with yield of 40%. The scale and corrosion inhibition tests of AEDP and HEDP(1-hydroxycthylidenediphos-phonic acid) showed that AEDP is better than HEDP.
