Solution thermodynamics in some nonpolar and polar stationary phases of 19 polyfunctional amines by means of gas-liquid chromatog. has been studied. The heats of solution, the excess heats of solution, the free energies, and entropies of the solution have been estimated The linear dependence of the thermodynamic properties on mol. weight or b.ps. of amines was shown to take place in nonpolar liquid phases. The maximum values of the thermodynamic properties were obtained in cases of polar liquid phases. Specific interactions take place between the amines and polar stationary phases: polyethylene glycols and Reoplex. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Related Products of 21867-64-1).
1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. A form in which piperazine is commonly available industrially is as the hexahydrate, C4H10N2. 6H2O, which melts at 44 °C and boils at 125â?30 °C. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.Related Products of 21867-64-1
