膦磺酸型阻垢剂的合成及性能研究

Synthesis and inhibitor performance of phosphated sulphonate acid

合成了3种二甲叉膦酸基氨基有机类磺酸型阻垢剂,考察了阻碳酸钙垢、磷酸钙垢、稳定锌、分散氧化铁、钙螯合值及缓蚀性能.结果表明,合成的膦磺酸型阻垢剂的性能优于常用的有机膦阻垢缓蚀剂ATMP、HEDP,与最优良的PBTCA相当,接近AA/AMPS,且在一定浓度下,具有一定的缓蚀作用.

Three kinds of antisludging agent containing dimethyl fork phosphonic acid amino and organic sulfonic acid are synthesized effectively.The effects to calcium carbonate dirty,calcium phosphate dirty,steady zinc,calcium chelation value and corrosion inhibition properties are investigated,respectively.The results show that the phosphine-sulfonic acid type scale inhibitors performance is greatly superior to the common organic phosphonate scale and corrosion inhibitor ATMP and HEDP,the effect of scale inhibitor is equivalent to the most excellent PBTCA and is close to AA/AMPS.Meanwhile,it has the properties of corrosion inhibition under a certain concentration.
