鉴于国内粮仓熏蒸剂缺乏,我们于一九五一年七月开始了氯化苦(三氯硝基甲烷)的制造研究。过去中外工业上制造氯化苦的方法多为苦味酸法,即以苦味酸为主要原料而制得之。此法在制造上,操作比较简易,然苦味酸易发生爆炸危险;在原料上,苦味酸为重要国防物资,且价昂货缺,不免成本过高。由于苦味酸法有上述缺点,并且根据文献及市场情况,得知三氯乙烯有做为氯化苦原科之可能性,以及三氯乙烯在国内市场有相当大的存量,价格较廉,
In view of the lack of domestic granary fumigants, we started the study on the manufacture of chloropicrin (TCL) in July 1951. In the past, most of the manufacturing methods of chloropicrin in Chinese and foreign industries are picric acid method, that is, picric acid is the main raw material. This method in the manufacture, the operation is relatively simple, but easy to picric acid explosion risk; in the raw material, picric acid is an important national defense supplies, and the price of goods shortage, inevitably the cost is too high. Due to the above shortcomings of picric acid, and according to the literature and market conditions, it is known that trichlorethylene has the potential of being used as chloropicrin, and that trichlorethylene has a relatively large stock in the domestic market with relatively low prices,
