METHOD OF PREPARING DIISOCYANATE COMPOSITION AND OPTICAL LENS
In an embodiment, in a process of manufacturing diisocyanate from diamine through diamine hydrochloride, an aqueous hydrochloric acid solution and an organic solvent may be used instead of hydrogen chloride gas, and solid triphosgene may be used instead of phosgene gas. In addition, the embodiment p...

| description | In an embodiment, in a process of manufacturing diisocyanate from diamine through diamine hydrochloride, an aqueous hydrochloric acid solution and an organic solvent may be used instead of hydrogen chloride gas, and solid triphosgene may be used instead of phosgene gas. In addition, the embodiment provides a method for manufacturing a diisocyanate composition and an optical lens having excellent yield and quality while reducing environmental problems by controlling a molar ratio of diamine hydrochloride and triphosgene within a specific range.
구현예는 디아민으로부터 디아민 염산염을 거쳐 디이소시아네이트를 제조하는 과정에서, 염화수소 가스 대신 염산 수용액과 유기 용매를 이용하고 포스겐 가스 대신 고상의 트리포스겐을 이용할 수 있다. 또한, 구현예는 디아민 염산염 및 트리포스겐의 몰비를 특정 범위 내로 조절함으로써, 환경 문제가 적으면서도 수율 및 품질이 우수한 디이소시아네이트 조성물 및 광학 렌즈의 제조방법을 제공한다. |
