摘要
用相转移催化聚环氧氯丙烷与亚硫酸盐反应合成磺酸聚醚。研究了溶剂、催化剂、磺化剂的种类及用量、反应条件对磺化率的影响。结果表明溶剂的极性、磺化剂的种类对磺化率有较大的影响 ,溶剂与水总用量一定时 ,溶剂用量越少 ,催化剂及磺化剂用量越大 ,反应温度越高 ,反应时间越长 ,磺化率越高。
Partly sulfonated polyepichlorohydrin was synthesized by phase transfer catalytic reaction of linear polyepicholohydrin oligmer and sulfite. It was investigated that the effects of type and amount of sulfite and catalyst as well as solvent,temperature and time of reaction on sulfonation. It is showed that the less amount of toluene, the more amount of sulfite and catalyst, the higher temperature, the longer time, the more sulfonation rate.
