Acetonitrile (ACN) is the chemical compound with formula CH3CN. This colourless liquid is the simplest organic nitrile. It is produced mainly as a by product of acrylonitrile manufacture. It is widely used as a polar aprotic solvent in synthetic chemistry, and as a medium-polarity solvent in HPLC.

Acetonitrile is mainly used as a solvent that is miscible with water and has a convenient liquid range. With a dipole moment of 3.84 D, acetonitrile dissolves a wide range of ionic and nonpolar compounds and with its low reactivity, it does so with minimal complications.

 

It is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry. Its low viscosity and low chemical reactivity make it a popular choice for liquid chromatography.

The Dimethylformamide, which we offer, is processed using the best chemicals that are sourced from reliable Vendors. We are a trustworthy Supplier and Exporter of Dimethylformamide.

Definition : Dimethylformamide is the organic compound with the formula (CH₃)₂NC(O)H. Commonly abbreviated DMF (though this acronym is sometimes used for dimethylfuran), this colourless liquid is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions. Pure dimethylformamide is odorless whereas technical grade or degraded dimethylformamide often has a fishy smell due to impurity of dimethylamine. Its name is derived from the fact that it is a derivative of formamide, the amide of formic acid. Dimethylformamide is a polar (hydrophilic) Aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions. Dimethylformamide can be synthesized from methyl formate and dimethyl amine or reaction of dimethyl amine and carbon monoxide.[1] Dimethylformamide is not stable in the presence of strong bases like sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid and is hydrolyzed back into formic acid and dimethylamine, especially at elevated temperatures.

Xylene (C₈H₁₀), any of three isomeric dimethylbenzenes  which have the same chemical formula, C₆H₄(CH₃)₂, but different molecular structure. All three are obtained from coal-tar distillate and petroleum as a mixture containing 50–60 percent by volume of m-xylene and 20–25 percent of each of the other isomers. The commercial xylene mixture is a colourless, nonviscous, flammable, toxic liquid that is insoluble in water but miscible with many organic liquids.

Uses :
Xylene is commonly used as a solvent for lacquers and rubber cements.  It is also used as solvents, as components of aviation fuel, and as raw materials for the manufacture of dyes, fibres, and films. Meta- and para-xylene undergo nitration and reduction to give xylidines and used in making dyes. The meta isomer also is converted to trinitro-t-butyl-m-xylene, or xylene musk, a component of perfumes. Oxidation of the xylenes gives monocarboxylic acids (toluic acids), and then dicarboxylic acids (phthalic acids).
