<br/><br/> Abstract:<br/><br/>This article discusses the influence of temperature and pressure on evaporation of trichloroethylene and heptane. The results show that the liquid content of the compound, the temperature and the ambient pressure influence the evaporation of volatile organic compounds in the soil. It has been shown that as the liquid content of compound increases in the soil until a value of 1.5%, the evaporation increases to reach a maximum before to decrease towards a zero value for liquid contents greater than 4%. Results also show that evaporation kinetics of trichloroethylene is approximately 15 times greater than that of heptane for all temperatures of 20°C, 30°C and 40°C. A decreasing dependence is also established between evaporation kinetics and the ambient pressure of the gas. At the same pressure, the volatilization doubles when the temperature passes from 20°C to 30°C and from 30°C to 40°C for both trichloroethylene and heptanes.<br/><br/> <br/>Keywords and phrases:<br/><br/>trichloroethylene, heptane, evaporation kinetics, temperature, gas pressure.
