Latest Patents

One of Harlan Frederick Reese's latest patents is a continuous process for diazomethane production from an N-methyl-N-nitrosoamine. This process allows for the safe production of diazomethane with minimal explosion hazards. It involves dissolving an N-methyl-N-nitroso amine in a mixture of water-miscible and water-immiscible organic solvents, followed by combining this solution with an aqueous inorganic base. The phases are then allowed to settle and are separated continuously. Another significant patent involves a process for forming a novel polyphenylene resin through the polycyclotrimerization of vinylethynylbenzene, diethynylbenzene, and phenylacetylene. This polymerization retains unreacted vinyl groups, making the resulting polymer suitable for high-performance carbon-carbon composites.
