ABSTRACT:
Isobutylene is reacted with alkanes having from 1 to 3 carbon atoms at 600.degree.-800.degree.C in the presence of an initiating agent, viz., oxygen alone or air, taken in an amount of 1 to 20 vol.% of the initial reaction mixture (as oxygen). The proposed method is simple to carry out from technological viewpoint, is based upon the readily available and inexpensive original stock and makes it possible to obtain the end products at high yields. Under optimum conditions of the realization of the proposed process the isobutylene conversion percentage is as high as 28 to 50, the total yield of the end products reaching 70 to 100 percent by weight as referred to the reacted isobutylene.
