PROCESS FOR PRODUCING HIGH PURITY ISOBUTENE BY DEHYDRATING TERTIARY BUTANOL
This is a process consisting of(i) continuously supplying aq. soln. contg. about 40-90 wt.% of TBA into rxn. container, (ii) dehydrating as a homogeneous liq. phase at 80-150 deg.C and at 5-25 bar on the fixed-catalyst-bed composed of strong acidic ionexchange resin, (iii) fractionally distg. homoge...
