Abstract
The physical solubility of hydrogen sulfide in aqueous solutions of 2-(tert -butylamino)ethanol neutralized with hydrochloric acid was measured in this work. Measurements were made over the temperature range 25 degreesC to 40 degreesC and the amine concentration range 0 to 50 mass %. The solubility d ata exhibit a minimum in the solubility with amine concentration. The data were correlated using the van-Krevelen-Hoftijzer method for the "salting-ou t" effect up to the minimum solubility and by a new empirical method over t he entire range of amine concentration.
