Identification of the adsorption of poly(ethylene glycol adipate) (PEGA) and tris(2-cyanoethyl)amine (TPA) on styrene-divinylbenzene porous polymer was performed with the use of the inverse gas-chromatog. method in finite concentration PEGA and TPA were applied in quantities ω = 10-6-10-3 mass fractions. As test sorbates n-propanol, n-butanol, and n-hexane used. The adsorption isotherm and the values of specific retention volumes were calculated via the Glueckauf method. It was found that the dependence of the retention volumes on the sorbate concentration in gas phase of the studied samples is well approximated by a power function corresponding to the Freundlich isotherm. The possibility of detecting PEGA and TPA on the surface of sorbent through the A coefficients of a power function was shown, and a linear dependence between the A values and neg. logarithm of ω was also found, making it possible to quant. determine TPA and PEGA on the surface of a sorbent. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Recommanded Product: 7528-78-1).
3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. Alkyl nitriles are sufficiently acidic to undergo deprotonation of the C-H bond adjacent to the CN group.Strong bases are required, such as lithium diisopropylamide and butyl lithium. The product is referred to as a nitrile anion. Recommanded Product: 7528-78-1
