Title: Innovations of Sung-Wan Jeon in Bio-Based Nylon Production

Introduction

Sung-Wan Jeon is a notable inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of bio-based materials, particularly in the production of nylon. With a total of three patents to his name, Jeon's work focuses on innovative methods that utilize biomass for sustainable manufacturing processes.

Latest Patents

One of Jeon's latest patents is a method for producing adipamide as an intermediate for the production of raw material for bio-based nylon. This method involves several steps, including the reaction of glucose, nitric acid, sodium nitrite, and potassium hydroxide to produce a glucaric acid potassium salt. Following this, glucamide is produced by reacting the glucaric acid potassium salt with an acidic solution, and potassium ions are removed. The process continues with the preparation of a reaction admixture that includes glucamide, a catalyst, hydrogen halide, and acetic acid. Finally, the reaction admixture is treated with hydrogen gas in a reactor to produce adipamide.

Another significant patent by Jeon is a method for manufacturing adipic acid using biomass. This method also begins with the preparation of a glucaric acid potassium salt through the reaction of glucose, nitric acid, sodium nitrite, and potassium hydroxide. Glucamide is then prepared from this salt, followed by the production of 2,4-hexadiene diamide through a deoxydehydration reaction. The adipamide is created by introducing the 2,4-hexadiene diamide, hydrogen, and a hydrogenation catalyst into a reactor for a hydrogenation reaction. The final step involves preparing adipic acid by introducing the adipamide and an aqueous hydrochloric acid solution into a reactor for hydrolysis at a specific temperature.
