With a total of 2 patents to his name, Nakayasu's work has had a notable impact on industrial applications.
Latest Patents
One of Nakayasu's latest patents is titled "Process for production of hydantoin derivatives." This innovative process allows for the industrial production of hydantoin derivatives at a high yield by reacting hydantoin with carbonyl compounds. The reaction occurs in the presence of amino acids or their salts, along with inorganic alkali compounds, all within a relatively short reaction time in an aqueous medium.
Another significant patent is "Process for separating iminodiacetic acid from aqueous glycine solution." This novel separation process involves adding sulfuric acid, in the presence of sodium salt, to an aqueous glycine solution. The pH of the solution is adjusted to 1.5 or less, which facilitates the crystallization of iminodiacetic acid from the solution. This method allows for the efficient recovery of glycine without causing undesirable accumulation of the iminodiacetic acid component in the mother liquor.
