Title: Il-Nam Jung: Innovator in Organochlorosilanes and Polysilamethylenosilanes
Introduction
Il-Nam Jung is a prominent inventor based in Songpa-gu, South Korea. He has made significant contributions to the field of organochlorosilanes and polysilamethylenosilanes, holding a total of 2 patents. His work focuses on improving processes and materials that have practical applications in various industries.
Latest Patents
One of his latest patents is titled "Process for preparing organochlorosilanes by dehydrohalogenative coupling reaction of alkyl halides with chlorosilanes." This invention relates to a method for preparing organochlorosilanes, specifically R R CHSiR Cl (I), through a dehydrohalogenative coupling of hydrochlorosilanes of HSiR Cl (II) with organic halides of R R CHX (III). The process utilizes quaternary phosphonium salt as a catalyst, which enhances economic efficiency and yield compared to conventional methods, as it requires only a catalytic amount of phosphonium chloride and allows for easy separation and recycling of the catalyst.
Another notable patent is "Polysilamethylenosilanes and process for their preparation." This invention introduces novel polysilamethylenosilane polymers characterized by a polysilane-polycarbosilane skeleton. These polymers can be synthesized in a one-step reaction from mixtures of chlorosilaalkanes and organochlorosilanes with alkali metals in suitable solvents. The resulting polysilamethylenosilane polymers are soluble, thermoplastic, and can be pyrolyzed to yield improved silicon carbide at atmospheric pressure.
