甲氧双丙嗪和呋喃丹的饱和蒸气压测定
- VAPOR PRESSURE DETERMINATION OF PROMETON AND CARBOFURAN
- 摘要：用气体饱和法测定了甲氧双丙嗪和呋喃丹在不同温度时的饱和蒸气密度和饱和蒸气压,依据Clausius-Clapeyron方程式,求出两化合物在常温下的气化热分别为28.65和29.75kcal/mol。对测定程序及饱和蒸气压和气化热的计算进行了讨论。
- Abstract：Vapor pressures of prometon and carbofuran at 15,25, 35 and 45°C were calculated based on vapor densities of the two compounds determined with gas-saturation method. Within the above temperature range, the vapor pressures of prometon and carbofuran are related to the reciprocal temperature by the equations: log Vp=15.79-6260.7/T and log Vp=15.82-6501.3/T respectively. The heats of vaporization calculated from the slopes of the above equations according to Clausius-Clapeyron equation are 28.65 kcal/mole for prometon and 29.75 kcal/mole for carbofuran, respectively. The procedures for the determination of vapor density and the calculation of vapor pressure and the heat of vaporization were also discussed.
