compound introduction
有类似光气味，溶于乙醇、苯、乙醚、氯仿及二氯甲烷等有机溶剂。遇热水及氢氧化碱则分解，遇冷水基本无作用。实际上不溶于水，可能形成光气，二氯甲烷中溶解度：588 g/L CH2Cl2 (20°C)。⑴ 医药合成：用于氯甲酸酯、异氰酸酯、聚碳酸酯、酰氯等精细化学品及阿洛西林、美洛西林、派拉西林及依那普利、降压等药物的合成。是生产抗生素类及其它药物的重要中间体。 ⑵ 农药制造：用于制造氨基甲酸酯类农药、脲类除草剂、合成除草剂、杀虫剂。 ⑶ 高分子材料合成：是合成聚氨酯类泡沫塑料的重要原料。 Solid phosgene substitute for a variety of applications, including the one-pot preparation of allyl azides from allyl alcohols and sodium azide, and the preparation of the esterification coupling reagent, di-2-thienyl carbonate, from 2(5H)-thiophenone. Used in the preparation of 2-chloronicotinaldehydes via cyclization of the corresponding enamides. Useful substitute for phosgene.
