在3L的高压磁力搅拌釜中通过催化胺化三官能团聚醚多元醇,研究了活化后雷尼镍催化剂的组成对反应的影响。实验结果表明,端氨基聚醚合成反应催化剂的铝含量约为20%(质量分数)时活性较高,产品的总胺值可以达到340mg KOH/g,这与传统雷尼镍催化剂的铝含量(〈10%(质量分数))不同。应用X射线衍射(XRD)对催化剂进行了表征,其化学组成则用等离子体发射光谱仪(ICP-AES)进行分析。反应原料、中间产物、胺化产物用傅立叶变换红外光谱(FT-IR)进行分析,反应原料、产物和尾气用气相色谱(GC)进行分析,并推测了反应路线。

The effect of the activated Raney nickel catalyst composition on the catalytic amination was studied by preparation of trifunctional amine terminated polyether in a magnetically stirred stainless steel autoclave.The experiments indicated that the catalyst with 20% aluminium was more effective for the catalytic amination of polyether polyols,and the total amine of the product was up to 340mg KOH/g.X-ray diffraction(XRD) was employed to characterize the catalyst properties and the chemical composition was analyzed by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The reaction route was deduced on the basis of the products and the off-gas analysis by gas chromatography(GC) and fourier transform infrared spectroscopy(FT-IR).
