Various commonly used organic solvents were dried with several different drying agents. A glovebox-bound coulometric Karl Fischer apparatus with a two-compartment measuring cell was used to determine the efficiency of the drying process. Recommendations are made relating to optimum drying agents/conditions that can be used to rapidly and reliably generate solvents with low residual water content by means of commonly available materials found in most synthesis laboratories. The practical method…

Assessment of the composition of aqueous-organic mixtures by solvatochromism of 4-[(octylylpyridinium)ethenyl]phenolate dyes

Determination of the water content in organic solvents has attracted a number of researchers in many fields of science in view of its importance in various chemical processes. The presence of water

Revisiting of Benzophenone Ketyl Still: Use of a Sodium Dispersion for the Preparation of Anhydrous Solvents

A facile generation of organic solvents of anhydrous grade can be performed by distillation from sodium–benzophenone ketyl, which is prepared from commercial sodium dispersion and benzophenone. The

Thermally Induced Silane Dehydrocoupling: Hydrophobic and Oleophilic Filter Paper Preparation for Water Separation and Removal from Organic Solvents

A new method for the preparation of hydrophobic and oleophilic filter paper, based on thermally induced silane dehydrocoupling between cellulose-based filter paper and octadecylsilane is reported, which has great potential for solvent drying and water separation.

Evaluation of air-free glassware using the ketyl test.

A method for quantitatively comparing air and moisture exclusion by air-free glassware is reported and low pressure/vacuum (LPV) NMR tubes demonstrated by far the best performance, compared to a variety of Schlenk flasks and standard N MR tubes.

Effects of Water

Tunable microwave-assisted method for the solvent-free and catalyst-free peracetylation of natural products

A totally green, solvent-free and catalyst-free microwave (MW)-assisted method for peracetylation of natural products such as oleuropein, alpha-hederin, quercetin and rutin, potentially easily scalable for industrial applications, including pharmaceutical, cosmetic and food industry.

Determination of Trace Water Content in Petroleum and Petroleum Products.

A simple, rapid, automated headspace gas chromatography (HSGC) method which requires modified instrumentation and ionic liquid stationary phases was developed and appeared to be unaffected by complicated matrixes.

Purification of tetrahydrofuran from aqueous azeotropic solution: continuous adsorption operation using molecular sieves

Abstract Purification of chemicals is industrially important. Tetrahydrofuran (THF) is a useful chemical and the industrial requirement is minimum 99.5 mass %. THF forms a homogenous minimum boiling
