Latest Patents

Motoshi Nakamura holds a patent for a method for producing propylene oxide. This method involves several key steps, including an oxidation step, a distillation step, an epoxidation step, and a separation step. The distillation step is crucial as it separates the reaction mixture containing cumene hydroperoxide into a concentrate and a distillate. The process is designed to maintain a specific ratio of the flow rate of the distillate to the flow rate of the reaction mixture, which ranges from 0.037 to 0.13. The epoxidation step results in a reaction mixture containing propylene oxide and cumyl alcohol, achieved by contacting the concentrate with propylene in the presence of a catalyst. The outlet temperature of the final reactor is carefully controlled to be between 115°C and less than 140°C.
