Ball-milled bamboo was pre-swelled with a cold aqueous solution of NaOH and urea, and then reacted directly with benzyl chloride to synthesize benzylated bamboo. The effects of the molar ratio of benzyl chloride to OH groups in the bamboo (1 to 4), the reaction temperature (70 to 110 °C), and the reaction time (2 to 8 h) on both the product yield and the degree of substitution (DS) were evaluat...

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...

Newly synthesized tocainide analogs were tested for their state-dependent affinity and use-dependent behavior on sodium currents (INa) of adult skeletal muscle fibers by means of the Vaseline-gap voltage clamp method. The drugs had the pharmacophore amino group constrained in position alpha [N-(2,6-dimethylphenyl)pyrrolidine-2-carboxamide (To5)] or beta [N-(2,6-dimethylphenyl)pyrrolidine-3-carb...

BiFeO3 (BFO), Bi0.86Sm0.07Eu0.07FeO3 (BSEFO), and Bi0.86Sm0.07Cd0.07FeO3 (BSCFO) nano powders were prepared by the sol-gel combustion method and the catalytic performances were evaluated in the acetylation reaction of benzyl alcohol. The physical chemical properties of the catalysts were character...

In this study, TiO2-10%wt. carbon nanotube (CNT) nanocomposite powders were synthesized by sol-gel method at various hydrolysis rate affected by different reaction agents of acetyl acetone and benzyl alcohol. Crystallization of TiO2 was then achieved through calcination at 400 °C. The properties of nanocomposite powder investigated by scanning electron microscopy, X-ray diffraction and diffuse ...

A series of copoly(alpha-amino acids) with varying percentages of hydrophilic (L-aspartic acid) and hydrophobic monomers (L-leucine, beta-methyl-L-aspartate, and beta-benzyl-L-aspartate) were implanted subcutaneously in rats and the macroscopic degradation behavior was studied. Three groups of materials (A,B,C) with different ranges of hydrophilicity were distinguished: A) hydrophobic materials...

We report a chemically conjugated bilayer graphene field effect transistor demonstrating a high on/off ratio without significant degradation of the on-current and mobility. This was realized by introducing environmentally stable benzyl viologen as an electron-donating group and atmospheric dopants as an electron-withdrawing group, which were used as dopants for the bottom and top of the bilayer...

abstract in order to study of two hormones effects of gibberellin and benzyl adenine on (zantedeschia aethiopica cv.childsiana) pot plant characteristics, non dormant rhizomes dipped preplanting in gibberellin solution with concentrations including (0, 100, 200 and 500 ppm) and sprayed in two weeks once to flowering time with benzyl adenine solutions including (0, 100, 200 and 500 ppm). interac...

Novel procedures have been developed to condense benzaldehyde effectively with beta-amino acid amides to cyclic benzyl aminals. Double carbamate protection of the heterocycle resulted in fully protected chiral beta-alanine derivatives. These serve as universal precursors for the asymmetric synthesis of functionalised beta(2)-amino acids containing acid-labile protected side chains. Diastereosel...
