In the first stage of this work, a thermodn. approach based on the equality of chem. potentials together with the original UNIFAC activity coefficient model was used to predict the surface tension of 11 different aqueous amine solutions over the entire concentration range at the temperature range of 293.15-348.15 K. The considered aqueous amine solutions include one of the following amines: monoethanolamine, diethanolamine, di-isopropanolamine, Me diethanolamine, 1-amino-2-propanol, triethanolamine, 3-dimethylamino-1-propylamine, 3-amino-1-propanol, dimethylethanolamine, 2-methylamino ethanol, and 2-ethylamino ethanol. The effect of temperature, amine concentration in the aqueous solution, and hydrophobic groups such as -CH2 and -CH3 on the surface tension of primary, secondary, and tertiary amines was investigated. In the second stage, the multilayer perceptron neural network model is designed to predict the surface tension of the aqueous solutions from two different classes of independent variables. The UNIFAC and two developed multilayer perceptron models were used to predict 650 surface tension values, which were in turn used to compare to exptl. data points with the average absolute relative deviations of 6.79, 1.17, and 1.12%, resp. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6Recommanded Product: 156-87-6)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Recommanded Product: 156-87-6
