氯气,这个众所周知的毒气,他在第一次世界大战时,不知杀害了多少性命?破坏了多少文明?但是,科学是要看人类如何去应用的。这种毒性强烈的毒气,只要用之于建设,他的力量是同样惊人的。近一二十年来,由于科学家的不断研究,氯气工业已跟随着有机化学的进步而有着惊人的发展;尤其是在第二次世界大战结束以后,他在化学工业中的地位,几有取代硫酸之势。在目前,他已不仅仅是用来漂白棉织物和纸张,不仅仅是用来消毒自来水,许多的有机染料,药品,杀虫剂等都 Chlorine, the well-known gas that he knew during the First World War, did not know how many lives were killed and how much civilization was destroyed? But science depends on how humans are applied. This toxic gas, if used for construction, is equally astounding. In the past decade or two, the chlorine industry has witnessed astonishing development with the progress of organic chemistry due to the continuous research of scientists. Especially after the end of World War II, his position in the chemical industry has been replaced by sulfuric acid The trend. At present, he has not only used to bleach cotton fabrics and paper, not only to disinfect tap water, many of the organic dyes, medicines, pesticides, etc.
