Abstract

Aliphatic ethers are prepd by contacting a charge contg a lower alkanol, (I) and =25 wt. % olefin, (II) in a (I):(II) mol ratio =1.5 at 26.7-93.8 (43.3-76.7 degrees C) pref. under 7-28.1 atmos, excess press. with a macro-crosslinked sulphonated ion exchange resin catalyst. In a pref. process a 4- or 3-4C petroleum raffinate stream contg. isobutylene as (II) is reacted with MeOH as (I) to form a prod contg. Me tert. Bu ether. The process is used for working up petroleum fractions contg. small amts of ios-olefins by in situ conversion of the olefines to ethers, and esp. prepn of Me tert. Bu ether which has a high octane no. and lower b. pt. than standard 8C alkylates prepd from isobutylene.
