 光气是重要的化工原料,在医药、农药、高分子材料、染料等化工领域应用十分广泛。光气化学品对国民经济起着重要作用。聚氨酯、聚碳酸酯都是光气化学品。氨基甲酸酯农药(杀虫剂、除草剂等)是最重要的高效低毒农药,如乙烯菌核利、绿麦隆、敌草隆、异丙隆等。新的广谱抗生素阿洛西林、兴奋平滑肌类新药卡巴胆碱、心血管新药赖诺谱利、抗肿瘤新药卡莫氟等医药产品都要使用光气化反应。但光气又是剧毒性气体,生产、运输、贮藏和使用都具有极大的危险性。利用气体光气的光气化反应,必须就地发生、就地使用,对于大吨位产品 (如TDI、MDI)的连续化生产,具有经济上的优势。但对于上述农药、医药等精细化学品的生产,均为品种多,吨位小的间歇操作,使用剧毒的气体光气不仅有毒害危险性,而且操作繁杂,给工业化造成了诸多困难。
 光气化反应往往只是精细化工产品多步合成中的一步反应,而光气生产厂家的光气又严禁运输,因此,一方面造成了目前许多光气厂家开工不足,另一方面一些需要光气的厂家许多用光气的精细化工产品长期不能投产,制约了我国精细化工的发展。
二、应用范围和生产条件:
 固体光气,分子式为C3Cl6O3或(ClCOCl)3 ,分子式与三分子光气相同,故又可称为三光气,白色结晶,熔点80oC,沸点206oC,具有酰氯气味,通常条件下安全、可运输,即使在206oC沸腾的高温条件下也仅有微量的光气放出,仅作为普通酰氯类化合物处理即可。但在与光气相似的条件下,一分子三光气可实现相当于三个分子的光气的光气化反应。固体光气作为光气的替代物可用于医药、农药及染料中间体的生产。
固体光气用于医药、农药、染料等精细化工产品的生产有如下特点:
1、安全。固体光气在通常条件下稳定,可运输和贮存,仅当普通有毒物处理即可。
2、反应条件温和,适于光气所发生的所有光气化反应。
3、用量少。克服了光气气固反应、剩余光气因逸出而造成浪费的缺点,反应可接近理论比(光气常需过量3-5倍)。
4、固光气可称量,避免了光气通大计量不准确的缺点。
5、反应设备简单,投资少,省去了光气废气的处理。
 综上所述,固体光气替代剧毒光气用于有机中间体的生产,从根本上消除了气体光气的毒害危险性。此外,还有可运输、可计量、减少消耗定额、操作方便、投资省等优点,对于批量小、品种多、价值高的精细化学品生产具有无可比拟的优越性。这一技术的推广应用,对光气精细化学品的传统技术改造和新产品的研究开发具有重大意义。
设备:1、搪瓷釜 1000L 1台附属设备:搪瓷搅拌、加热冷却夹套(20-120oC) 高压汞灯(或紫外灯)400~1000W。2、氯气分布器(搪瓷)。 3、过滤机 l台.4、石墨冷凝器1台。 5、氯化氢气体吸收系统:降膜吸收塔2台,盐酸储槽1台,碱填料吸收塔1台,碱储槽1台。6、引风机1台。7、陶瓷泵  2台,碱泵1台。8、氯气瓶 0.5或1.0t  10个。9、溶剂罐 500L  1个。10、箱式干燥器(50oC)
三、获得的专利等知识情况: 具有自主知识产权。
四、规模与投资、成本估算:
 若碳酸二甲酯按14000元/t,氯气接2000元/T计算,四氯化碳6000元/t。其原材料成本约为8500元/T,仅比光气(约5000元/t)略高。但由于固体光气投料接近理论量,而光气需用3-5倍过量,因此实际使用成本比光气低,具有广泛的工业化前景。
   设备费:20万元;    流动资金:10万元。    原料费:8500元/t;    人工费:240元/t;    动力费:200元/t;    管理费:200元/t;    税:(免)    总成本:9140元/t.    获纯利:2万元/t(不包括盐酸副产)。 产品售价若按3万元/吨计(实际售价为4万/吨),年产100吨,则可获利200万元/年。 设备50万元人民币。
