ABSTRACT:
An alkene skeletal isomerization process is employed in an integrated process for the production of tertiary ether, e.g., tertiary amyl methyl ether (TAME) from the reaction of isoamylenes (iC.sub.5.sup.= 's) with methanol in the presence of an acid cation exchange resin. A light naphtha from a fluid catalytic cracking unit is used as the source of the iC.sub.5.sup.= 's in a process which separates the C.sub.5 containing fraction from the light naphtha, selectively hydrogenates the di-olefins contained in the C.sub.5 containing fraction, reacts the iC.sub.5.sup.= 's contained in the C.sub.5 containing fraction with methanol to form TAME, separates the TAME from the unreacted materials as a product, separates methanol from the unreacted materials, isomerizes a portion of the nC.sub.5.sup.= 's to iC.sub.5.sup.= 's , for example using a zeolite or an alumina treated with methanol, and use of the isomerization product as feed for a TAME reactor.
