摘要
一种以环氧丙烷或丙二醇与五氧化二磷或磷酸,水为溶剂,以酸性催化剂会成三(羟丙基)磷酸酯.以此为基础,与其它缓蚀、阻垢剂进行复配,组成多组份复合配方(以下简称复合配方).该复合配方具有较优异的缓蚀阻垢性能,与锌具有良好的协同效应,符合环保“低磷”要求.
Tri (hydroxy propyl) phosphate has been synthesized from epoxypropane or propylene glycol and P2O5 or H3PO4 using water as solvent and acid as catalyst. It is formulated with other inhibifors and scale prevention agents to make multicomponent complex formulation. The formulation has excellent inhibition and scale revention performance. It has good synerzistic effect with Zinc and complies with environmental protection requirement-low phosphorus.
