Added saturated vapor pressure
Thread Content
Does anyone know the pressure of formic acid vapor at 230 degrees Celsius? Thank you
There is a software for looking up the physical properties of pure substances; you can give it a search

Calculation of the saturated vapor pressure of formic acid at different temperatures: lgP = A – B/(t + C), where P is the vapor pressure of the substance, in millimeters of mercury； t: temperature, °C. For formic acid CH2O2: A=6.94459, B=1295.26, C=218.0. The calculated values are 11308 mm of mercury and 14.88 kg/cm2. 2. Additionally, the boiling point of formic acid at atmospheric pressure is 100.8°C; the pressure you need is not necessarily the saturated pressure – it depends on how much control you want to achieve
