3月20日早晨东京地铁发生毒气事件,经日本自卫队化学处理班检验,发现其中含有“沙林”剧毒物质。沙林是化学毒剂中毒性最强、作用最迅速的“速杀性毒剂”——“神经性毒剂”的主要代表。化学名称为:甲基氟膦酸异丙酸。沙林是一种无色有微弱水果味的透明液体,工业品略显黄、棕色。沸点较高为151.5℃,凝固点为一54℃,液体比重(20℃)为1.096,与水及多种有机溶剂(醇、醚、酮、酯、卤代烷、苯等)可互溶。性质稳定,水解
On the morning of March 20, a poisonous gas incident occurred in the Tokyo Metro. After being tested by the Japan Self-Defense Forces Chemical Treatment Class, it was found that it contained “Sarin” highly toxic substances. Sarin is one of the most toxic and rapidly acting “poison” and “neurotoxic agents” of chemical agents. The chemical name is: methyl fluorophosphonic acid isopropionic acid. Sarin is a colorless, fruity, transparent liquid with a slight yellowish-brown color. The highest boiling point is 151.5 ℃, the freezing point is 54 ℃ and the liquid specific gravity (20 ℃) is 1.096. It can be miscible with water and various organic solvents (alcohols, ethers, ketones, esters, alkyl halides and benzene). Stable, hydrolyzed
