Title: The Innovations of Michael J Clarke
Introduction
Michael J Clarke is a notable inventor based in Hull, GB, recognized for his contributions to the field of chemical additives. With a total of seven patents to his name, Clarke has made significant advancements in the development of fuel and lubricant compositions.
Latest Patents
Clarke's latest patents include the "Resin-free succinimides process of making, and compositions containing." This invention focuses on novel pure hydrocarbyl succinylating agents and their derivatives. The method involves preparing pure substituted succinylating agents and utilizing them as additives for fuels and lubricants. The hydrocarbyl substituted succinylating agents are characterized by their purity, as the mole ratios of succinyl groups to hydrocarbyl groups are substantially the same. This is achieved by reacting an olefin polymer, such as poly(iso)butylene, with maleic anhydride, followed by solvent extraction to eliminate impurities.
Another significant patent is related to "Fuel compositions containing a polyisobutene succinimide detergent." This fuel composition consists of a major amount of liquid hydrocarbon fuel and a polyisobutene succinimide derived from the reaction of a polyisobutene-substituted succinic acylating agent and an amine. The polyisobutene-substituted succinic acylating agent is obtained through a thermal route, utilizing a highly reactive polyisobutene.
