chemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Concentration fluctuations in a mesoscopic oscillating chemical reaction system.
Under sustained pumping, kinetics of macroscopic nonlinear biochemical reaction systems far from equilibrium either can be in a stationary steady state or can execute sustained oscillations about a fixed mean. For a system of two dynamic species X and Y, the concentrations n(x) and n(y) will be constant or will repetitively trace a closed loop in the (n(x), n(y)) phase plane, respectively. We s...
متن کاملScalar Mixing and Chemical Reaction Simulations Using Lattice Boltzmann Method
We simulate scalar mixing and chemical reactions using the lattice Boltzmann method. Simulations of initially non-premixed binary mixtures yield scalar probability distribution functions that are in good agreement with direct numerical simulation (of NavierStokes equation) data. One-dimensional chemically-reacting ow simulation of a premixed mixture yields a ame speed that is consistent with ex...
متن کاملPeculiar Concentration Dependence of H/D Exchange Reaction in 1-Butyl-3-methylimidazolium Tetrafluoroborate-D2O Mixtures
We have investigated the H/D exchange reaction between heavy water and an ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]), throughout the whole concentration region as a function of D2O mol% at room temperature. We expected that the extent of the H/D reaction would increase linearly with increasing content of D2O, but the results show an extended N-shaped behavior havi...
متن کاملHydrogen Isotope Exchange Reaction
polarization causes Q1ftf partly to cance12 Qu' and so to reduce the calculated MO approximation DNQ, making it agree better with the observed value.2~ This improvement most probably much outweighs the contrary effects obtained by optimizing Z*. The effect on DNQ of using polarized AO's is quite different in the AO than in the MO approximation. Referring to an earlier paragraph on the variation...
