Abstract

An experimental study of the absorption of CS$_{2}$ in the secondary amine diethanolamine(DEA) was performed in this work. The primary objectives were to investigate an analogy between N2O and CS$_{2}$ permitting estimation of the physical solubility and diffusivity of the sulfur gases in the reacting amino solutions. The solubilities of CS$_{2}$ in water at 25, 40 and 6$0^{\circ}C$ has been measured. The data show fair agreement with previous literature values. The solubility of CS$_{2}$ in 5-25 weight % polyethylene glycol has been measured in order to investigate a possible analogy between CS$_{2}$ and N$_{2}$O The diffusivities of CS$_{2}$ in water and the reaction rate between CS$_{2}$ and DEA has been measured at 25 and 4$0^{\circ}C$, using a wetted sphere apparatus operated at approximately 1/3 atmospheres pressure, which is a previously untried method.
