双三羟甲基丙烷磷酸酯盐织物抗静电剂的合成工艺研究

Study on synthetic process of di-trimethylolpropane phosphate salt as antistatic agent

以三氯氧磷(PO)和双三羟甲基丙烷(DTMP)以及氢氧化钾为原料,合成了织物抗静电整理剂双三羟甲基丙烷双磷酸酯钾盐。主要考察了原料配比、反应温度及反应时间对反应过程的影响,确定了最佳反应条件:n(PO)∶n(DTMP)=4∶1,反应温度为70℃,反应时间为5h,收率为95.04%。

The antistatic agent,Di-trimethylolpropane phosphate salt has been synthesized lrom phos- phorus oxychloride （PO）,Di-trimethylolpropane （DTMP） and potassium hydroxide. The effects of re action conditions, such as mole ratio of PO to DTMP, reaction temperature and reaction time were examined in this paper. The optimum esterification reaction conditions are as follows：the mole ratio is that n（PO） ： n（DTMP） =4 ： 1;the reaction temperature is 70 ℃ ;the reaction time is 5 h. The yield of esterification is 95.04% under the reaction conditions.
