Title: Satoru Kohno: Pioneering Innovations in Refrigeration Technologies

Introduction

Satoru Kohno, an accomplished inventor based in Settsu, Japan, has made significant contributions to the field of refrigeration technology. With a total of six patents to his name, Kohno has established himself as a key player in developing efficient methods for chemical separation processes.

Latest Patents

One of Kohno's latest patents is titled "Process for preparing pentafluoroethane," which outlines a method for efficiently separating pentafluoroethane (HFC-125) from a mixture with chloropentafluoroethane (CFC-115). This innovative method utilizes extractive distillation to achieve a high concentration of HFC-125. The process involves using a hydrofluorocarbon compound, particularly 1,1,1,2-tetrafluoroethane, as an extractant. This extractant facilitates the separation, resulting in concentrated CFC-115 as a distillate and a mixture of HFC-125 with a reduced content of CFC-115, which can be further purified by distillation and reused in the process.
