In 2019,Fluid Phase Equilibria included an article by Leontiadis, Konstantinos; Tzimpilis, Evangelos; Aslanidou, Dimitra; Tsivintzelis, Ioannis. Application of 156-87-6. The article was titled 《Solubility of CO2 in 3-amino-1-propanol and in N-methyldiethanolamine aqueous solutions: Experimental investigation and correlation using the CPA equation of state》. The information in the text is summarized as follows:
The solubility of CO2 in 1.3M and 2M aqueous N-methyldiethanolamine (MDEA) and 3-amino-1-propanol (MPA) solutions was exptl. measured at 298, 313, 323 and 333 K, using a pressure decay method. Since only limited exptl. data exist in literature for MPA aqueous systems, the results of this study were compared with literature data mainly for 2M MDEA solutions, showing satisfactory agreement. The obtained new exptl. data were used to parameterize the Cubic-plus-Association (CPA) equation of state using a pseudo chem. reaction approach, i.e. to account for chem. interactions as very strong specific intermol. interactions, which is a crude approximation, but is necessary for applying equation of state models. It was found that the model satisfactorily describes the exptl. data using six or four binary parameters for the CO2-MPA or CO2-MDEA interactions, resp., which, however, are less than the number of adjustable parameters in similar literature models. The experimental part of the paper was very detailed, including the reaction process of 3-Aminopropan-1-ol(cas: 156-87-6Application of 156-87-6)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Application of 156-87-6
