Title: Shean-Jeng Jong: Innovator in Chemical Purification

Introduction

Shean-Jeng Jong is a prominent inventor based in Tao-Yuan, Taiwan. He has made significant contributions to the field of chemical purification, holding a total of 11 patents. His innovative methods have advanced the efficiency and effectiveness of purifying complex chemical compounds.

Latest Patents

Among his latest patents is a method and device for purifying 1,4-bis(bromodifluoromethyl)benzene. This invention addresses the challenges associated with purifying and separating crude products of this compound. By mixing diphenylmethane, which has a higher boiling point and does not interact with 1,4-bis(bromodifluoromethyl)benzene, with the crude products, the method allows for effective evaporation. The purity of the vaporized product is then detected, ensuring that only those reaching the expected purity are collected, resulting in high-purity 1,4-bis(bromodifluoromethyl)benzene. Another notable patent is a method for purifying Piribedil. This process involves mixing Piribedil solid with a purity of 98% by weight with water, boiling the mixture, and then adding 95% ethanol to form a clear liquid. The hot clear liquid is filtered, and upon cooling, a white crystal with a purity of 99.8% by weight of Piribedil is obtained.
