Title: Xuelei Cui: Innovator in Chemical Engineering
Introduction
Xuelei Cui 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 2 patents, Cui's work has garnered attention for its practical applications and efficiency.
Latest Patents
Cui's latest patents include a method for preparing isophorone diisocyanate. This method involves a three-step process: first, isophorone is reacted with hydrogen cyanide in the presence of a catalyst to obtain isophorone nitrile. Next, the isophorone nitrile is reacted with ammonia gas and hydrogen, again in the presence of a catalyst, to produce isophorone diamine. Finally, the isophorone diamine undergoes 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 for efficient airflow through the heater body, which consists of a stereoscopic network structure formed by interweaving electrical heating wires. The heater is characterized by its simple structure, low pressure loss, uniform heating, and high heat utilization ratio during the preparation of isocyanate.
