Capture, storage and valorisation of CO2 are efficient solutions to reduce the emissions of greenhouse gas. To improve these technologies, there is a need to have a good knowledge of the interactions between CO2 and some current solvents. In this article, the solubility of CO2 in methanol, ethanol and 1,2-propanediol is measured by a constant-volume method for temperatures between 283.15 K and 373.15 K and for pressures below 6.0 MPa. The same method is used for glycerol for pressures up to 2.0 MPa. For all of the studied solvents, the solubility increases when temperature decreases and when pressure increases. No literature data was available for this wide range of temperature for ethanol, methanol, 1,2-propanediol and glycerol. Henry's law constants are calculated for each temperature and are compared between to one another. The solubility of CO2 in these solvents increases in the following order: glycerol less than 1,2-propanediol less than methanol approx.= ethanol.
