Dimethyl carbonate synthesis via carbon dioxide activation in the presence of iodide catalysts

Ammonium or alkali metal iodides are effective catalysts for the synthesis of dimethyl carbonate via carbon dioxide activation in the presence of trimethyl orthoesters or dimethyl acetals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 450412-29-0. Category: iodides-buliding-blocks.

Removal and sequestration of iodide using silver-impregnated activated carbon

Two silver-impregnated activated carbons (SIACs) (0.05 and 1.05 wt % silver) and their virgin (i.e., unimpregnated) granular activated carbon (GAC) precursors were investigated for their ability to remove and sequester iodide from aqueous solutions in a series of batch sorption and leaching experiments. Silver content, total iodide concentration, and pH were the factors controlling the removal mechanisms of iodide. Iodide uptake increased with decreasing pH for both SIMS and their virgin GACs. The 0.05% SIAC behaved similarly to its virgin GAC in all experimental conditions because of its low silver content. At pH values of 7 and 8 there was a marked increased in iodide removal for the 1.05% SIAC over that of its virgin GAC, while their performances were similar at a pH of 5. Scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analyses prior to reaction with iodide showed the presence of metallic silver agglomerates on the 1.05% SIAC surface. After the reaction, elemental mapping with EDX showed the formation of silver iodide agglomerates. Oxidation of metallic silver was observed in the presence of oxygen, and the carbon surface appears to catalyze this reaction. When the molar ratio of silver to iodide was greater than 1 (i.e., M-Ag,M-SIAC > M-I,M-TOTAL), precipitation of silver iodide was the dominant removal mechanism. However, unreacted silver leached into solution with decreasing pH while iodide leaching did not occur. When MAg,SIAC M-I,M-TOTAL, silver iodide precipitation occurred until all available silver had reacted, and additional iodide was removed from solution by pH-dependent adsorption to the GAC. Under this condition, silver leaching did not occur while iodide leaching increased with increasing pH.

Kinetic catalytic-spectrophotometric determination of race amount of iodide

A new, simple, sensitive and selective catalytic spectrophotometric method was developed for the determination of ultra trace amounts of iodide. The method is based on the catalytic effect of iodide on the oxidation of Indigo carmin by iodate. The reaction was monitored spectrophotometrically by measuring the decrease in absorbance of Indigo carmin at 612 nm with a fixed-time method. The decrease in the absorbance of Indigo carmin is proportional to the concentration of iodide in concentration range 40.0-200.0 ng/ mL,with a fixed time of 0.5-2.5 min from initiation of the reaction. The limit of detection is 34 ng/mL iodide.The relative standard deviation of 0.060 and 0.10 mu g/mL iodide was 1.8 and 2.2%, respectively. The method was applied to the determination of iodide in water.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 60166-93-0 is helpful to your research. Product Details of 60166-93-0.

Etching of mercuric iodide in cation iodide solutions

The surface properties of mercuric iodide after etching in various cation iodide solutions have been investigated in terms of dissolution rate, morphology, electrical properties and reaction with water vapour. No significant differences have been observed in the etching rates. However, dissolution of HgI2 in NH4I, NaI, KI or RbI leaves the surface more or less covered with a residual iodo mercurate compound whose electrical properties and stability with regard to humidity may noticeably influence the behaviour of mercuric iodide devices. The smallest effect has been observed for etching in NaI. (c) 2005 Elsevier B.V. All rights reserved.

PNEUMATOAMPEROMETRIC FLOW-INJECTION DETERMINATION OF IODIDE

A simple flow-through analytical system with pneumatoamperometric detection for the determination of iodide is presented. Iodide is detected after oxidation to iodine by iodate in tartaric acid medium. Iodide at concentrations below 100-mu-g 1(-1) can be detected even in the presence of a large excess of chlorides (more than 10(4)-fold). The effect of other interfering anions was studied and minimized by introducing an auxiliary oxidant into the flow system.

Capture of Iodide by Bismuth Vanadate and Bismuth Oxide: An Insight into the Process and its Aftermath

As a result of the scarcity of iodine, as well as its threat to the environment if it is present in excess, iodine as a waste needs to be captured. Compared with ion-exchange resins and Ag-containing materials, which are popular iodide adsorbents, Bi-containing compounds show some important advantages, such as high iodide-capture capacity and fast kinetics. In this study, two Bi-containing compounds, BiVO4 and Bi2O3, were investigated comprehensively for iodide immobilization. The influence of the pH, iodide/adsorbent ratio, temperature, crystallite size, and competing ions was explored, with a view to optimization of the capture process. Further study of the iodide-adsorbed bismuth compounds confirms that the capture of iodide by BiVO4 and Bi2O3 is a chemisorption process with the formation of bismuth oxyiodide (BixOyIz). Furthermore, iodide ions are able to penetrate into the bulk of BiVO4 and Bi2O3, which is believed to be responsible for their high capture capacity. The application of BixOyIz as a photocatalyst has also been examined in Cr-VI reduction. This result makes the capture of iodide by BiVO4 and Bi2O3 even more environmentally friendly as the photocatalytic application of the iodide-containing adsorbents not only avoids the production of secondary waste but may help to solve other environmental issues.

Iron-Catalyzed Carboiodination of Alkynes

An iron-catalyzed carboiodination of alkynes with alkyl iodides at room temperature was developed. This method could provide synthetically useful vinyl iodides with general alkyl chains, fluoroalkyl group, ester, and cyano group. Conjugated alkynes or unconjugated alkynes were both suitable for this transformation. A radical pathway was proposed for the mechanism and acetyl tert -butyl peroxide was selected as the radical initiator. Alkenes could also be applied to this chemistry and produce more complex alkyl iodides.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 460-37-7, in my other articles.
