乙二胺四甲叉膦酸钠合成方法的改进

The Improvement of the Synthesis Method of EDTMPS

对乙二胺四甲叉磷酸钠 (EDTMPS)的传统生产方法进行了改进 ,针对原有产品存在的质量问题和生产过程中的氯化氢泄漏问题。从原料的成分、质量、配比及生产工艺过程都进行了较为系统的实验研究。新配方、新工艺、使生产过程易于控制 ,无氯化氢泄漏。在解决了产品质量问题的同时 ,又提高了原产品中乙二胺四甲叉磷酸钠的含量 。

The improvement of the traditional manufacture method of EDTMPS was introduced in this paper. To the question about quality of the original product and the leakage of HCL in the process. A lot of research had been done from Component , quality and proportion of the raw material to manufacture technology process in lab. The new formula and technology made it easy to control manufacture process without leaking of HCL.This result not only resovled the quality of product but also increased proportion of EDTMPS in the original product. It was convenient to be stored and used .Some factories applied the new formula and technology in the industrialize manufacture,the cost of the product was reduced,the Sales amount of the product was increased.
