Another important property of acetonitrile is its boiling point, which is about 82 degrees celsius. Willhite CC [1981]. … The Journal of Physical Chemistry A 2002 , 106 (31) , 7147-7154. Show this safety data sheet to the doctor in attendance. This is why acetonitrile is classified as a polar compound. Table 12. This reagent is intended for N-terminal protein sequencing applications. The data of Dreisbach [2] are merely an estimate according to the boiling point based on the Cox diagram. 20% Acetonitrile / 80% water Revision Date 18-Jan-2018 9. Accordingly for their separation, heterogeneous distillation, extractive distillation, and solvent extraction have been used. Some of the processes used to obtain high purity acetonitrile include solvent extraction combined with a conventional distillation to separate very dilute solutions [2]. The smallest organic nitrile is ethanenitrile, CH 3 CN, (old name: methyl cyanide or acetonitrile - and sometimes now called ethanonitrile). Index-No. It is a precursor to propylamines by hydrogenation. Colour: Colorless. Chemsrc provides Acetonitrile(CAS#:75-05-8) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Percentage of A. by weight in mixture. Boiling point/boiling range : 82 °C Note: The information regarding the boiling point is that of the solvent. Now you can calculate its boiling point under any pressure. You can now roughly evaluate its boiling point. Used in making perfumes. Odor: Aromatic odor. The values of the vapour pressure of acetonitrile obtained by us are near to the data of Brown [1]. Values for relative polarity, eluant strength, threshold limits and vapor pressure have been extracted from: Christian Reichardt, Solvents and Solvent Effects in Organic Chemistry, Wiley-VCH Publishers, 3rd ed., 2003. Take water for example. Acetonitrile boils at 81.6 ºC and water boils at 100 ºC. Acetonitrile (methyl cyanide; ethanenitrile). Acetonitrile and water forms an azeotropic mixture having a boiling point of 76.5 °C and containing approximately 82.2 wt % acetonitrile under atmospheric pressure. Miller's Home.

MD Calculated Structural Properties of Clusters in Liquid Acetonitrile/Water Mixtures with Various Contents of Acetonitrile. Taste: Sweetish taste. The present work aims to resolve theoretically the puzzling effect of downshifting of the νOH stretching mode of phenol, complexed with acetonitrile, as the latter concentration increases, via performing a thorough search of the potential energy surface of the interaction of phenol with acetonitrile at the modest MP2/6-31+G(d,p), MP2/6-31G(d), and B3LYP/6-31+G(d,p) computational levels. It is a C-3 building block in the preparation of the drug flopropione by the Houben-Hoesch reaction. Structure Of Acetonitrile - C 2 H 3 N or CH 3 CN. Toxicology studies: acetonitrile. with methylbenzen e (1:1) [ACD/Index Name] acetonitrile toluene. Propionitrile is a solvent similar to acetonitrile but with a slightly higher boiling point. In: Toxicology of drugs and chemicals. Acetonitrile, compd. Othmer D.F. In acetaldehyde, they are at an angle, so the (vector) sum will be less. Ind.Eng.Chem. The data of Heim [4] deviate from ours especially at lower temperatures. Boiling points.
