Abstract
PURPOSE: To prepare an 8C olefin free from quaternary carbon atoms, in high yield, by the selective co-dimerization of isobutene and n-butene existing in a 4C fraction in the presence of a Ziegler-Natta catalyst containing the third component comprising diphenoxymethane, etc.
CONSTITUTION: Isobutene and n-butene in a 4C fraction containing n-butene, butanes, etc. and 5W55% of isobutene, are selectively co-dimerized in the presence of a Ziegler-Natta catalyst composed of Ni salt of an aliphatic organic acid and an alkylaminum chloride and added with 0.5W5mol, based on 1mol of Ni, of a third component comprising a compound of formula R1ORxOR2 [R1 and R2 are phenyl or alkyl; Rx is a structure having a 1W10C straight-chain methylene links, a structure derived from the above structure by substituting the H atom of the methylene group in the main chain with an alkyl, or a polyether structure of formula (m is 2W 4, l is 1W4)], e.g. 1,2-diphenoxyethane.
