|Section2= |Section3= }} Cacodyl, dicacodyl, tetramethyldiarsine, alkarsine or minor part of the "Cadet's fuming liquid" (after the French chemist Louis Claude Cadet de Gassicourt) (CH3)2As—As(CH3)2 is a poisonous oily liquid with a garlicky odor. Cacodyl undergoes spontaneous combustion in dry air. ==Preparation== Cacodyl oxide is prepared by the reaction of potassium acetate with arsenic trioxide. :4 CH3CO2K + As2O3 → As2(CH3)4 + 2 K2CO3 + 2 CO2 A subsequent reduction or disproportionation of the substance under the reaction conditions yields a mixture of several methylated arsenic compounds. A far better synthesis was developed which started from the dimethyl arsine chloride and dimethyl arsine. :As(CH3)2Cl + As(CH3)2H → As2(CH3)4 + HCl 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「Cacodyl」の詳細全文を読む スポンサード リンク
