Diffusion and chemical reaction in cation exchange resin: hydration of isobutylene.

Isobutylene is a versatile and reactive chemical intermediate of considerable industrial significance. At the present time, its most important use is in the manufacture of butyl rubber and of di- and poly-isobutylenes. Another important product of isobutylene, tertiary butyl alcohol (t-butanol), forms an intermediate in the manufacture of oil soluble phenol formaldehyde resin
