Alkylation of isopentene with isopentane and sulphuric acid can be accomplished in two minutes reaction time, provided that the reacting substances are emulsified during the reaction. The most favourable ratio of the reacting substances (volumes) is about 5 of isoparaffin; 2 1/2 of sulphuric acid...
On the basis of an analysis of the products of sulphuric acid alkylation of isobutane with olefins in the presence of anthracene (an effective hydride ion acceptor), the possibility has been shown of implementing a process route including detachment of the hydride ions from the olefins with the ...
