摘要
在绝热旋转弹量热计中测定了2,2′-二氯乙基sulfìde(芥子气)的燃烧焓和生成焓。炸弹过程已更正:C 4 H 8 Cl 2 S(液体)+ 7 O 2 (g) + 98 H 2 O(液体)→4 CO 2 (g) +盐酸[2 + H 2 4 + 100 H 2 O](液体)得到了以下值:ΔH C°(25°C) = - 3163.49±1.26焦每摩尔和ΔH f°(25°C) = - 200.57±1.58焦每摩尔。。
The Enthalpies of Combustion and Formation of 2,2'-Dichloroethyl Sulfide.
The enthalpies of combustion and formation of 2,2'-dichlorethyl sulfìde (mustard gas) have been determined by combustion in an adiabatic rotating-bomb calorimeter. The bomb process has been corrected to: for which the following values were obtained: .
