The synthesis of isopropyl tert-butyl ether over cation-exchange resins of various morphology

What is it about?

The acidic and catalytic characteristics of various types of sulfonated cation-exchange resins, differing in the location of the active phase, in the synthesis of isopropyl tert-butyl ether (IPTBE) were studied. It was established that a sulfonated cation-exchange resin on a wide-pore silica gel support has the highest selectivity with respect to IPTBE (100%). It was shown that mineral–organic sulfonated cation-exchange resins have higher activity than bulk sulfonated cation-exchange resins due to the accessibility of their acid centers for the reagents.
