Experimental investigation of carbon dioxide hydrate formation conditions in the presence of KNO3, MgSO4, and CUSO4

Experimental data on the incipient conditions for carbon dioxide hydrate formation in aqueous solutions of KNO3, MgSO4, and CuSO4 were obtained in the temperature range of (273 to 287) K, in the pressure range of (0.77 to 4.34) MPa, and in salt concentrations ranging from (2.22 to 40.17) mass %. A variable-volume sapphire cell was used for the measurements.
