in this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid peg1000-dail[bf4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. this novel methodnot only enhanced the yield, but also made the operating units easy workup. the catal...

The present study has been focused on the acid and base transesterification of animal fats (dairy cow and beef) to produce biodiesel by varying process parameters such as catalyst amount, catalyst nature, reaction time and temperature. The maximum biodiesel yield after acid catalysis was 94.1 ± 2.43 and 98.4 ± 2.3 percent for dairy cow and beef t...

nano-cufe2o4 catalysts with different cu/fe molar ratios (cunfemo(n+1.5m)) were prepared by hydrothermal method. the thermal decomposition performance of cunfemo(n+1.5m) on cuso4 were determined with tg-dsc method to evaluate its catalytic activity and the roasted product was characterized by xrd. the results showed that cunfemo(n+1.5m) had superior catalytic properties and efficiency to cuso4 ...

MgO ultrathin films are of great technological importance as electron tunneling barrier in electronics and spintronics, template for metallic clusters catalysis molecular networks 2D electronics. The wide band-gap allows a very effective decoupling from the substrate. morphology detailed structure interface crucial applications, controlling electronic transfer. Using surface x-ray diffraction, ...

Betulin, being a pentacyclic triterpene alcohol and an extractive from birch bark, along with its oxo-derivatives, has broad range of physiological properties interest for synthesis pharmaceuticals. Instead oxidizing betulin strong toxic agents the present study shows possibility using liquid-phase oxidation air over supported Ag NPs catalysts as alternative method oxo-derivatives. Based on cat...
