Single crystals of 8-hydroxy-5-nitroquinolinium p-toluene sulfonate (HNT) were grown by the slow evaporation solution growth technique. The structure was elucidated single-crystal X-ray diffraction analysis, and crystal belongs to monoclinic system with space group C2/c. crystallinity HNT studied powder analysis. presence functional groups determined FT-IR spectral band gap energy is estimated ...

Polyvinyl alcohol (PVA) is a hydrophilic polymer well known for good film forming properties, high water vapor permeance JW, and low nitrogen permeance. However, depending on molar mass temperature, PVA swells strongly in until complete dissolution. This behavior affects the usability of aqueous environments makes cross-linking necessary if higher structural integrity envisaged. In this work, n...

UV curable PUA resin was successfully synthesized from polyol based on sustainable resource originated from itaconic acid (IA), isophorone diisocyanate (IPDI) and 2-hydroxyethyl methacrylate (HEMA). A polyol was synthesized by condensation reaction of IA with 16-hexanediol in the presence of p-Toluenesulfonic acid (pTSA). The synthesized PUA resin was characterized for its structural elucidatio...

The therapeutic application of vitamin E is seri­ ously limited by its very low solubility in aqueous phases, and tocopherols cannot be used when in­ stant adm inistration of a strong antiradical and antioxidant agent is needed. To increase solubility in w ater and facilitate perm eability through cellu­ lar m em branes tocopherol can be attached to a carbohydrate moiety [1]. The synthesis of s...

A number of SO3H-functionalized solids (biochar, montmorillonites, carbon and halloysite nanotubes) has been studied as catalysts in the cascade Prins-Ritter reaction (-)-isopulegol with benzaldehyde acetonitrile for synthesis octahydro-2H-chromene amides (as 4R- 4S-isomers). high selectivity to these products at 30 °C presence H2O was observed on modified chlorosulfonic acid (CSA) reaching 84%...
