Latest Patents

One of Nakaya's latest patents is titled "Process for producing xylylenediamine." This invention provides a method for producing xylylenediamine by supplying a solution of phthalonitrile dissolved in a solvent to a reactor filled with a catalyst. The process includes halting the supply of the solution, bringing a washing liquid into contact with the catalyst, and then resuming the supply of the solution. This innovative approach allows for the continuous use of the catalyst over an extended period, significantly reducing catalyst-related costs.

Another notable patent is the "Production method of xylylenediamine." This method involves the hydrogenation of dicyanobenzene, which is obtained by the ammoxidation of xylene. The process ensures a high yield of xylylenediamine while prolonging the life of the catalyst. By dissolving molten dicyanobenzene in a solvent containing liquid ammonia, Nakaya's method effectively removes certain compounds and enhances the efficiency of the hydrogenation process.
