摘要

用氧弹量热仪测定了噻吩(二苯二硫)的燃烧焓。生成焓是用现有文献中的数据推导出来的。获得的结果如下:C 12 H 8 S 2 (C) + 17 O 2 (g) + 228 H 2 O(液体)= 12 CO 2 (g) + 2 (H 2 4 + 115 H 2 O](液体)ΔH C°(25°C) = - 7253.27±1.40焦每摩尔(- 1733.65±0.33千卡每摩尔)ΔH f°(25°C) = 184.23±1.50焦每摩尔(44.03±0.36千卡每摩尔)的比较给出了这项调查的结果与先前的调查人员。

The Enthalpies of Combustion and Formation of Thianthrene.

The enthalpy of combustion of thianthrene (diphenylene disulfide) has been determined in an oxygen-bomb calorimeter. The enthalpy of formation has been derived using data from the available literature. The results obtained are as follows: $C_{12} H_{8} S_{2} (c) + 17 O_{2} (g) + 228 H_{2} O (liq) = 12 {CO}_{2} (g) + 2 [H_{2} {SO}_{4} + 115 H_{2} O] (liq)$ $Δ H_{c}^{°} (25^{°} C) = - 7253.27 \pm 1.40 kJ / mol (- 1733.65 \pm 0.33 kcal / mol)$ $Δ H f^{°} (25^{°} C) = 184.23 \pm 1.50 kJ / mol (44.03 \pm 0.36 kcal / mol)$ A comparison is given of the results of this investigation with those of previous investigators.
