Low molecular weight olefins (such as propene, 2-methylpropene, 1-butene and 2-butenes, pentenes and hexenes) can be converted by oligomerisation to a product which is comprised of oligomers and which is of value as a high-octane gasoline blending stock and as a starting material for ...
This invention relates to the manufacture of organic sulphonates in which the sulphonic group. is attached to an aliphatic carbon atom, and more particularly to the manufacture of alkali metal alkenes
