WebbHow do you calculate the boiling point from vapor pressure? At the critical point, the enthalpy of vaporization is found to approach zero. Until this point, the enthalpy of vaporization can be reduced by the influence of pressure, i.e., by increasing the pressure.Thus, a higher vapor pressure corresponds to a lower boiling point and vice … Webb2 feb. 2011 · Propylene (C 3 H 6) is a colorless gas. It is obtained by thermal cracking of ethylene. At low concentration it forms an explosive and flammable mixture with air, while at high concentrations it can cause asphyxiation and skin burns.
