Oxidative Chlorination of Aromatic Compounds in Aqueous Media
An efficient method for the synthesis of chlorinated arenes is disclosed. The method involves the use of NaClO3 as oxidant and HCl as chlorinating agent in aqueous medium under mild conditions to chlorinate the aromatic compounds in good to excellent yields (75-96%). The reagent system is efficient, organic solvent-free and easy to handle.
متن کاملBleaching of kaolins and clays by chlorination of iron and titanium
The quality of the clays and over all kaolin is measured in function of iron content, since this element gives an undesirable reddish color to this type of minerals. The use of chlorination for iron and titanium removal from different clay and kaolin minerals, used in Argentinian ceramic industry, has been investigated to establish reaction mechanisms, precautions and optimal conditions to blea...
متن کاملReaction-Mediator-Based Chlorination for the Recycling of Titanium Metal Scrap Utilizing Chloride Waste
In this study, a novel chlorination technique for metallic titanium (Ti) was devised in order to establish a recycling process that uses both Ti metal scrap and iron chloride (FeClx) waste, and its feasibility was demonstrated. Direct reaction between Ti and FeClx has drawbacks such as slow kinetics of Ti chlorination and high volatilization of FeClx. To overcome these, the authors proposed a c...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولGraphene from Amorphous Titanium Carbide by Chlorination under 200°C and Atmospheric Pressures
The synthesis of graphene via decomposition of SiC has opened a promising route for large-scale production of graphene. However, extremely high requirements for almost perfectly ordered crystal SiC and harsh process conditions such as high temperatures (>1200 °C) and ultra-high vacuum are two significant challenges hindering its wide use to synthesize graphene by decomposition of SiC. Here, we ...
