摘要
A new solid acid resin catalyst with high thermal stability-sulfonated poly (phthalazinone ether sulfone ketone) (S-PPESK) resin was prepared through sulfonation method and applied to isobutene oligomerization. S-PPESK showed high catalytic activity and excellent dimerization selectivity under low reaction temperature conditions. The thermal stability of S-PPESK was measured by pretreatment method, the pretreatment temperature was 180 degreesC which was about 40 degreesC higher than that for with commercial sulphuric acid resin catalyst. S-PPESK exhibits good catalytic activity, excellent dimerization selectivity and high thermal stability in isobutene oligomerization. It is a promising resin catalyst.
