Title: Teruyuki Ninomiya: Innovator in Polyol Production
Introduction
Teruyuki Ninomiya is a prominent inventor based in Okayama-ken, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of polyols and trimethylolpropane. With a total of 9 patents to his name, Ninomiya's work has advanced the efficiency and purity of chemical processes.
Latest Patents
Ninomiya's latest patents include a groundbreaking process for producing a polyol. This process involves reacting an aliphatic aldehyde with formaldehyde in the presence of a basic catalyst. It features a concentration step that removes water and unreacted formaldehyde through distillation. Additionally, the method includes an extraction step to isolate the polyol and a washing step to separate the extract into an oil layer and an aqueous layer. By utilizing a specific aliphatic aldehyde as the extracting agent, this method achieves high purity polyhydric alcohol with minimal byproduct formation.
Another notable patent is his method for producing highly pure trimethylolpropane. This method transforms crude trimethylolpropane, derived from a reaction of n-butyl aldehyde and formaldehyde, through a two-stage process involving aldol condensation and a crossed Cannizzaro reaction. By pre-removing high-boiling components and inorganic salts, Ninomiya's process allows for the effective removal of impurities during subsequent heat treatment, resulting in a highly pure final product.
