An experimental study of the absorption of CS2 in the secondary amine diethanolamine(DEA) was performed in this work. The primary objectives were to investigate an analogy between N2O and CS2, permitting estimation of the physical solubility and diffusivity of the sulfur gases in the reacting amine solutions. The solubilities of CS2 in water at 25, 40 and 60℃ has been measured. The data show fair agreement with previous literature values. The solubility of CS2 in 5-25 weight % polyethylene glycol has been measured in order to investigate a possible analogy between CS2 and N2O. The diffusivities of CS2 in water and the reaction rate between CS2 and DEA has been measured at 25 and 40℃, using a wetted sphere apparatus operated at approximately 1/3 atmospheres pressure, which is a previously untried method.
