ABSTRACT:
This invention relates to a process for producing substituted acylating agents by the reaction of an enophile with an ene by the thermal route wherein (a) the molar ratio of the enophile to the ene is at least 3:1 and (b) the reaction pressure is raised to above 20 psig an least after addition of the enophile reaction to the reaction is completed and is maintained substantially constant until at least 80% of the ene reactant has been converted to the corresponding acylating agent. The agents so produced are substantially free of chlorine and can be further reacted with an amine or a hydroxy compound to form a derivative which can be used as an additive for a lubricating oil or a fuel.
