Theoretical study of phthalane oxidation and effect of substituents by using Hyperchem program

The effect of substituents on the relative stabilization energy (ERS) of phthalane-X carbocations has been studied with PM3 semi-empirical molecular orbital theory. The results show that the amino group gives ERS less than zero for very big amount and that will increase stability of carbocation by π-electron donation, whereas the nitro group gives height amount of ERS more than zero and that will...

Preconcentration of Ni(II) from sample water by modified poly (ethylene terephthalate)-grafted-acrylic acid/acryl amide fiber

Modified poly (ethylene terephthalate)-grafted-acrylic acid/acryl amide fiber was prepared by adding acrylic fibers to methanolamine (PET-AA/AAm) with different concentration solutions. The stability of a chemically modified PET-AA/AAm fiber especially in concentrated hydrochloric acid which was then used as a recycling and Preconcentration reagent for further uses of modified PET-AA/AAm fiber. The application of this...
