Title: Yong Yu - Innovator in Chemical Engineering

Introduction

Yong Yu is a prominent inventor based in Yantai, China. He has made significant contributions to the field of chemical engineering, particularly in the development of innovative methods for producing isocyanates. With a total of 3 patents to his name, his work has garnered attention for its practical applications and efficiency.

Latest Patents

Yong Yu's latest patents include a method for preparing isophorone diisocyanate. This method involves a three-step process: first, reacting isophorone with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile; second, reacting the isophorone nitrile with ammonia gas and hydrogen to produce isophorone diamine; and third, subjecting the isophorone diamine to a phosgenation reaction to yield isophorone diisocyanate. Notably, the method ensures that the content of impurities containing a secondary amine group in the isophorone diamine is ≤0.5 wt, which reduces the presence of hydrolyzed chlorine in the final product and improves its yellowing resistance.

Another significant patent involves a heater designed for heating and vaporizing droplets in a gas stream. This heater features a housing with an airflow inlet and outlet, allowing air to flow through a stereoscopic network structure formed by interweaving electrical heating wires. The design promotes uniform heating and high heat utilization during the preparation of isocyanate, making it an efficient tool in chemical processes.
