Process for preparing organic isocyanates |
摘要 |
An improved process for preparing organic isocyanates is disclosed. An organic amine is reacted with phosgene to yield a reaction product, through which hydrogen chloride gas is passed in the presence of an inert organic solvent whereby the gas included in the reaction product is removed and the acid substances and hydrolyzable chlorine-containing substances included therein are minimized. |
