Development And Validation

A simple analytical method was developed for determination of chloride content in polymeric materials. The procedure comprises of two steps, the dissolution of the polymer by alkaline fusion followed by indirect spectrophotometric analysis of the chloride based on the absorption at 460 nm of Fe(SCN)2+, a product of the reaction between chloride ion and a mixture of mercury (II) thiocyante and ferric ion. A non-linear calibration curve was constructed from 0.5 to 20 ppm with R2 = 0.9991; the limit of detection and quantitation were of 0.325 and 1.083 ppm, respectively. The recovery of the whole procedure was higher than 92.9 % with a RSD ~ 2.4 %. The developed procedure was applied to animated poly(divinylbenzene-co-vinyl benzyl chloride) in order to investigate the extent of amination of the base material.

High Throughput Manner

<div> <div> <div> <p>This article reviews prior work studying reaction kinetics in solution, with the goal of using this information to improve detailed kinetic modeling in the solvent phase. Both experimental and computational methods for calculating reaction rates in liquids are reviewed. Previous studies, which used such methods to determine solvent effects, are then analyzed based on reaction family. Many of these studies correlate kinetic solvent effect with one or more solvent parameters or properties of reacting species, but it is not always possible, and investigations are usually done on too few reactions and solvents to truly generalize. From these studies, we present suggestions on how best to use data to generalize solvent effects for many different reaction types in a high throughput manner. </p> </div> </div> </div>

Abstract NAS 825 is a corrosion-resistant nickel alloy that has resistance to both oxidizing and reducing environments, and with 42% nickel, the alloy is very resistant to chloride-ion stress-corrosion cracking. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-694. Producer or source: Nippon Yakin Kogyo Company Ltd.
