Latest Patents
One of Torii's latest patents is a method of hydrogenating phenol. This innovative process allows for the hydrogenation of phenol industrially and advantageously. The method utilizes a supported rhodium and/or ruthenium catalyst, enabling efficient hydrogenation at lower reaction temperatures compared to prior art. The process incorporates carbon dioxide at temperatures ranging from 20 to 250°C and pressures between 0.1 to 50 MPa, making it an environmentally friendly alternative that avoids harmful organic solvents.
Another significant patent is for a process for producing lactam. This invention provides an efficient method for continuously synthesizing lactam in high-temperature, high-pressure water. By introducing an oxime as a reaction substrate and an acid into a reaction zone with flowing high-temperature, high-pressure water, the method suppresses oxime hydrolysis. This allows for the efficient and continuous synthesis of lactam at high temperatures of at least 250°C and pressures of at least 15 MPa.
