Latest Patents
Lao-Jer Chen's latest patents include a process for the production of aliphatic isocyanates. This innovative process involves reacting an aliphatic or cycloaliphatic primary amine with phosgene in the presence of an inert solvent. The initial reaction temperature is maintained between 100 and 130°C, and it is subsequently ramped to 150 to 180°C during the reaction. The solvent to amine weight ratio is carefully controlled between 95:5 to 80:20, while the total reaction pressure is kept between 50 and 350 psig. The amine is rapidly dispersed in the phosgene through injection in a region of high efficiency mixing, ensuring optimal reaction conditions.
