磺化聚醚砜酮树脂的催化活性
摘要:
采用磺酸化的方法制备得到了一种新型的磺化聚醚砜酮树脂催化剂（S-PPESK）,并采用滴定法对这种催化剂进行了表征.在异丁烯的低聚反应中,对这种新型树脂催化剂的催化活性进行了细致的研究，磺化聚醚砜酮树脂催化剂在反应中表现出了很好的催化活性和优良的二聚选择性.实验结果显示，当催化剂的磺化度（S.D.）增加时，即催化剂的酸量增加时，异丁烯的转化率和三聚物的选择性也增加，但二聚物的选择性降低，四聚物的选择性则几乎没有变化.

Catalytic Activity of Sulfonated Poly (phthalazinone ether sulfone ketone) Resin
Abstract:
A novel sulfonated poly (phthalazinone ether sulfone ketone) resin catalyst (S-PPESK) was prepared by means of sulfonation method and characterized with titration. The catalytic activity of this new resin catalyst in the isobutene oli merization was measured in detail; it exhibited od catalytic activity and excellent isobutene dimerization selectivity. The results indicated that when the sulfonation degree (S.D.) of the catalyst increased, i.e. the acid volume of the catalyst increased, the conversion for isobutene and the selectivity for trimer increased also, while the selectivity for dimer decreased, and the selectivity for tetramer was almost unchanged.
