The Initiation Mechanism of the Isoolefin Oligomerization Reaction in the Presence of Ethylaluminum Dichloride – Protonodonor Complex Catalysts

The mechanism of isoolefins initiation in the presence of ethylaluminum dichloride – proton donor (water, phenol, hydrochloric acid) complex catalysts has been studied by ab initio HF.3.21G. The energetics of these reactions was estimated, the values of its activation energy and thermal effects were obtained. It was found that among the studied catalysts, an increase in the activation energy of the reaction of initiation of oligomerization of isoolefins contributes to an increase in the selectivity of the process.
