Ionic liquids (ILs), considered to be a relatively recent magical chemical due their unique properties, have a large variety of applications in ll areas of the chemical industries. The areas of application include electrolyte in batteries, lubricants, plasticizers, solvents and catalysis in ynthesis, matrices for mass spectroscopy, solvents to manufacture nano-materials, extraction, gas absorpt...

Baker’s yeast catalyzes the asymmetric reduction of prochiral ketones in water and in various organic solvents. The reaction in water, which is the first solvent of choice for bio-reactions, led to a high product yield and enantiomeric excess, but the low miscibility of organic molecules in water resulted in lower conversions when more hydrophobic ketones were used. Petroleum-based solvents suc...

Organic solvents are chemically different compounds with one common feature: They dissolve fats, oils, resins, cellulose, acetate, and cellulose nitrate, which makes them widely used in industry. Most often organic solvents are used in paint and lacquer industries, in production of pesticides, explosives, plastic, rubber, cellulose, air conditioners, in pharmaceutical industry, and in leather i...

Nanotechnology is new form of technology which has produced a great development in variousfields. Nanoparticles are of the great scientific interest as they are effectively a bridge between bulk material and atomic & molecular structures. Nanoparticles are the particle that have size 1 to 100 nm and possess due to large surface area to volume ratio & smaller size. Different types of nanom...

Nuclear clarifying agents (NCAs) are a class of substances frequently used as additives in the production polymers to improve their physical properties. Some EU regulated under Commission Regulation (EU) no. 10/2011 can be food contact plastics. However, limited analytical methods for analysis currently available, part due poor solubility most common organic solvents and lack standards known pu...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

Subtilisin and alpha-chymotrypsin vigorously act as catalysts in a variety of dry organic solvents. Enzymatic transesterifications in organic solvents follow Michaelis-Menten kinetics, and the values of V/Km roughly correlate with solvent's hydrophobicity. The amount of water required by chymotrypsin and subtilisin for catalysis in organic solvents is much less than needed to form a monolayer o...

Industrial applications such as batteries and bio-separations require modeling the thermodynamic properties of mixed solvent electrolytes. Thermodynamic models for electrolytes often consider solvents a dielectric continuum characterized by their constant. Therefore, accurate predictions physically sound model constant solvents, depending on temperature, pressure, mixture composition. We presen...

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...
