  Abstract
  Separation performance of Faujasite NaX zeolite membrane was studied for water-unsymmetrical dimethylhydrazine (UDMH) mixture using pervaporation (PV). A comprehensive transient model was developed using COMSOL Multiphysics software version 5.2. The developed unsteady state 2D model was capable of predicting concentration distribution in both membrane and feed phases. The membranes showed good selectivity towards water in the water-UDMH mixtures. Water permeates faster because of its preferential adsorption into the Nano-pores of the hydrophilic zeolite membrane. In PV of water-UDMH mixtures, the membrane exhibits a hydrophilic behavior, with a high selectivity towards water and a good flux. The best NaX membrane had a water flux of 2.67 kg/m2.h at 27oC. The best PV selectivity was obtained to be 40.

  Abstract
  Chiral auxiliary molecule is used as consideration interacting with intermolecular interactions and different enantiomer intermediates. Partition of racemic mixture exploitation chiral auxiliary the primary reaction of enantiomers with chiral auxiliary to formation of diastereomers Diastereomers has completely dissimilar properties therefore it`s merely separated by posture or crystallization. Partition of Enantiomers useful an essential industrial and sustainable issue. Synthesis of desymmetrization and lots of partition may be a crucial methodology for the desymmetrization of the racemic mixture.

  Abstract
  Carbon-hydrogen bond activation is a burgeoning area of organometallic chemistry with the potential to provide a wealth of improved protocols in synthetic organic chemistry. However, today a lot of challenges stay that continue to limit its synthetic utility. An analysis of some current advance in the area of carbon-carbon bond formation via direct carbon-hydrogen activation is presented. So using different synthetic method Carbon-hydrogen bond activation possible and even the attract of this new and growing field, definitely prompt raised academic and industrial attention, and improved protocols for fascinating and synthetically applicable reactions are possible to still seem.

  Abstract
  The liquid-phase catalytic hydrogenation of dimethyl-nitrobenzene (DN) to Dimethyl-aniline (DA) was carried out in ethanol using 5% Pd/C as a catalyst. The effects of hydrogen partial pressure (400–1000 kPa), reaction temperature (343–403 ), catalyst loading (5–15 g/lit), speed of stirring range (200-800 rpm) and dimethyl-nitrobenzene concentration (0.12–0.75 mol/lit) on the hydrogenation of dimethyl-nitrobenzene and the yield of Dimethyl-aniline have been studied. Dimethyl-aniline was the only reaction product, generated through the hydrogenation of the Nitro group of dimethyl-nitrobenzene. The effects of hydrogen partial pressure, catalyst loading, dimethyl-nitrobenzene concentration and temperature on the reaction conversion have been reported. Near first-order dependence on dimethyl-nitrobenzene concentration and hydrogen pressure were observed for the initial rate of dimethyl-nitrobenzene hydrogenation over the 5% Pd/C catalyst. Conventional Arrhenius behavior was exhibited by catalyst, Pd/C showed activation energies of 614 J/mol. A simple power law model was used for analysis of the reaction kinetic data.
