Abstract

PURPOSE: Dehydrated heteropolyacid is used as a catalyst to effect the selective oligomerization of isobutylene in an olefin mixture containing n-butylene and isobutylene at a temkerature lower than 120°C, thus producing the titled substance that is used as a dispersing agent for pigments with industrial advantage.
CONSTITUTION: Heteropolyacid and/or heteropolyacid salt, which was previously trated to remove a part or all of the hydrated water, such as phosphomolybdenic acid or silicotungstenic acid is used as a catalyst to effect the selective oligomnerization of isobutylene in an olefin mixture containing n-butene and isobutylene at a temperature lower than 120°C, preferably of 40W80°C, to produce the titled compound. As the above olefine mixture is preferably used the spent BB containing n-butene as the major component and a small amount of isobutyline, which is obtained by distilling off butadiene from the C4 fraction resulting from naphtha cracking process and further removing isobutylene from the resultant spent BB.
