Solubility of CO2 in glycerol at high pressures

The solubility of CO2 in liquid glycerol was measured at the temperatures of 353.2 K, 393.2 K and 423.2 K, and pressures up to 32 MPa. The static synthetic method was used in a variable-volume view cell. The solubility of CO2 in glycerol was enhanced by pressure increase and by temperature decrease. When compared with reported values for alcohols with the same chain length, the solubility increased in the following order: glycerol < 1,2-propylene glycol < 1-propanol < 2-propanol.
