In present work we try to detect changes on styrene-divinylbenzene microporous polymer surface by adsorption energy distribution function (heterogeneity function, 锠?. Polymer surface was modified by 0.1-104 ppm of polyethylene glycol, polyethylene glycol adipate and tripropionitrilamine. Heterogeneity function was calculated from the inverse gas chromatog. data. It was determined that function 锠?was capable to detect surface properties variations only at 103 ppm and above modifier impregnation. If one use the first derivative of 锠? it allows detecting surface properties changes after 0.1-1 ppm modifier impregnation. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Computed Properties of C9H12N4).
3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C閳ユ弲 bond formation or by dehydration of primary carboxamides. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Computed Properties of C9H12N4
