Chlorine Dioxide-Iodide-Methyl Acetoacetate Oscillation Reaction Investigated by UV-Vis and Online FTIR Spectrophotometric Method
In order to study the chemical oscillatory behavior and mechanism of a new chlorine dioxide-iodide ion-methyl acetoacetate reaction system, a series of experiments were done by using UV-Vis and online FTIR spectrophotometric method. The initial concentrations of methyl acetoacetate, chlorine dioxide, potassium iodide, and sulfuric acid and the pH value have great influence on the oscillation ob...
متن کاملInvestigation of phase - equivalent potentials by a halo transfer reaction
Using the supersymmetric quantum mechanics we investigate the wave function-sensitive properties of the supersymmetric potentials which have received a lot of attention in the literature recently. We show that a su-perdeep potential and its phase-equivalent shallow-partner potential give very similar rms values for the weakly bound systems such as the deuteron and 11 Be nuclei. Although the cor...

A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...

فرهنگ های گوناگون دریافت ها و تعبیر های مختلفی از تناسب و ادب دارند. بنابراین، ارتباط میان فرهنگی خطرات ذاتی خطای ارتباطی را نشان می دهد. این پژوهش به منظور تعیین وقوع انتقال منظورشناختی زبان در زبان بینابینی زبان آموزان ایرانی، اختلاف منظورشناختی زبان را بین فارسی و انگلیسی در کنش های کلامی پاسخ تحسین و انتقاد بررسی می کند.داده ها از میان 33 آمریکایی انگلیسی زبان، 85 زبان آموز ایرانی در سطوح م...
15 صفحه اولSolvent effects on methyl transfer reactions. 2. The reaction of amines with trimethylsulfonium salts.
The reaction of ammonia and pyridine with trimethylsulfonium ion has been studied in gas phase and solution. Density functional theory at the B3LYP/6-31+G level was used to describe the energy changes along the reaction coordinate in the gas phase, and the self-consistent isodensity polarizable continuum model (SCI-PCM) was used to calculate the effect of cyclohexane and dimethyl sulfoxide as t...
