| titleOfInvention | Method of preparing diisocyanate composition and optical lens |
| abstract | In an embodiment, in the process of preparing diisocyanate from diamine through diamine hydrochloride, an aqueous hydrochloric acid solution may be used instead of hydrogen chloride gas, and solid triphosgene may be used instead of phosgene gas. In addition, the embodiment provides a diisocyanate composition with excellent yield and quality and a method for manufacturing an optical lens with less environmental problems by adjusting the total content of cations in the diisocyanate composition within a specific range. |
