Latest Patents
John G Frey, Jr. holds a patent for a process for producing cyclic compounds. This invention includes methods of processing an initial di-carbonyl compound by converting it into a cyclic compound. The cyclic compound is then reacted with an alkylating agent to form a derivative that has an alkylated ring nitrogen. The invention encompasses a method of producing an N-alkyl product. The ammonia content of a solution is adjusted to create a ratio of ammonia to di-carboxylate compound ranging from about 1:1 to about 1.5:1. An alkylating agent is added, and the initial compound is alkylated and cyclized. The invention also includes methods for making N-methyl pyrrolidinone (NMP). Aqueous ammonia and succinate are introduced into a vessel, and the ammonia is adjusted to provide a ratio of ammonia to succinate of less than 2:1. A methylating agent is reacted with succinate at temperatures ranging from greater than 100°C to about 400°C to produce N-methyl succinimide, which is then purified and hydrogenated to form NMP. He has 1 patent to his name.
