Title: Kozo Tachibana: Innovator in Optical Isomer Separation

Introduction

Kozo Tachibana is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of chemistry, particularly in the area of optical isomer separation. With a total of 7 patents to his name, Tachibana's work has advanced the methods used in this specialized field.

Latest Patents

One of his latest patents is focused on a filler used for separating optical isomers and the process for achieving this separation. The objectives of this invention are to provide a filler capable of efficiently carrying out the optical resolution of optical isomer mixtures. This invention also outlines a process for separating optical isomers by utilizing a simulated moving bed chromatography with the filler. The filler is made of a carrier that supports a specific amount of an optically active high molecular weight compound. The separation process is conducted under conditions where the capacity factors have specific values.

Another significant patent involves a method of producing ethyl (3R, 5S, 6E)-7-[2-cyclopropyl-4-(fluorophenyl)quinoline-3-yl]-3, 5-dihydroxy-6-heptenoate. This method employs liquid chromatography using a packing material that consists of a carrier and a polysaccharide derivative. In this method, some or all of the hydrogen atoms of hydroxyl and amino groups of the polysaccharide derivative are substituted with various substituents, such as a carbamoyl group. This innovative method enhances the productivity of producing the (3R, 5S, 6E) isomer compared to conventional methods.
