三羟甲基丙烷合成工艺开发进展

The technological progress on synthesis of trimethylolpropane

阐述了以正丁醛、甲醛为起始原料 ,以NaOH为催化剂 ,一步法合成三羟甲基丙烷和用N(C2 H5) 3 为催化剂 ,两步法合成三羟甲基丙烷的工艺技术。介绍了此产品的国内外生产情况及发展前景。

The synthesis technology of trimethylolpropane from n-butanal and formaldahyde with NaOH catalyst via one step method and with N(C_2H_5)_3 catalyst via two step mathod is discussed.And this paper introduces production distribution of trimethylolpropane outside and inside the country and its market prospect.
