|Section2= |Section3= }} Simazine is an herbicide of the triazine class. The compound is used to control broad-leaved weeds and annual grasses. ==Preparation== Simazine may be prepared in the laboratory from cyanuric chloride crystals and a strong solution of ethyl amine (at least 50 percent by number in water). The reaction is highly exothermic and is therefore best carried out in an ice bath below 10 °C. It is also essential to carry out the synthesis in a fume hood since cyanuric chloride decomposes at high temperatures into hydrogen chloride and hydrogen cyanide, both of which are highly toxic by inhalation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Simazine」の詳細全文を読む スポンサード リンク
