摘 要: 强酸性苯乙烯系阳离子交换树脂001×7#和D01#两种树脂分别进行了深度磺化改性,研究了改性前后的各种树脂的酯化催化活性和不同温度下的热稳定性。结果发现,改性后,树脂的催化活性明显提高,在低温场合下,改性树脂的热稳定性与未改性的树脂相近,但在高温场合下,改性树脂的热稳定性明显不如未改性的树脂。 The strong acidic cation exchange resin of polystyrene(001×7#and D01# resin)are modified through sulfonation and then their catalytic activity and thermal stability are studied.The modified products have higher catalytic activity than primal resins and same thermal stability at low temperature, but at high temperature, their thermal stability is lower than that of primal resins.
