ABSTRACT:
Tertiary olefins are obtained in pure form by cleavage of the pertinent tert.alkyl ethers with simultaneous formation of the pertinent alcohols on strongly acidic cation exchangers in the H.sup.+ form. This cleavage is carried out at elevated temperature and atmospheric to superatmospheric pressure. The process is carried out in such a fashion that the ether to be cleaved is employed as a mixture with water. The water may be employed in an amount from 2-50% by weight, relative to the amount of the ether to be cleaved. Suitable ethers to be cleaved are those based on tertiary C.sub.4 -C.sub.7 -olefins and primary C.sub.1 -C.sub.4 -alkanols.
