Abstract

Results of a study of the reaction products of asphaltene sulfonation with sulfuric acid in various temperature and time ranges have been described. The maximum sulfur content in sulfonated cation exchangers at an asphaltene sulfonation temperature of 100 and 120°С and a reaction time of 2 h has been determined. The maximum static exchange capacity of 4.3 meq/g has been found for the products of sulfonation with a sulfuric acid–oleum mixture. The asphaltene-based strongly acidic sulfocationite has been tested in the 2,2-dimethyl-1,3-dioxolane synthesis reaction.

沥青质强酸性磺化阳离子交换剂的合成及其在2,2-二甲基-1,3-二氧戊环合成反应中的催化性能测定

摘要

已经描述了在不同温度和时间范围内沥青质磺化与硫酸的反应产物的研究结果。确定了在沥青质磺化温度为100和120°C，反应时间为2小时的条件下，磺化阳离子交换剂中的最大硫含量。对于用硫酸-发烟硫酸混合物进行磺化的产品，发现最大静态交换容量为4.3 meq / g。已经在2，2-二甲基-1，3-二氧戊环合成反应中测试了基于沥青质的强酸性亚硫酸盐。
