补充资料:大孔强酸性苯乙烯系阳离子交换树脂
分子式:
CAS号:

性质:白色至灰褐色不透明球状颗粒,不溶于水、酸、碱和各种有机溶剂。在不同型式或不同介质中,体积只有微小的膨胀或收缩变化。大孔型树脂与同类的普通凝胶型树脂的化学结构相同,但物理结构各异,主要区别在于它们的孔隙度不同乙大孔树脂内部存在永久孔道和由此形成的较大内表面,一般每克树脂表面积在5m2以上,交换速度快,应用范围广,除适用于水中无机离子交换外,还能吸附高分子有机物。在悬浮聚合时,于单体混合液中加入致孔剂。聚合后除去溶剂,再经洗滤、干燥、过筛、磺化、转型和水洗即得成品。主要用于高纯水制备,尤其适用于高速混床凝结水处理装置,也用作有机反应的催化剂等。
