Can acetonitrile (cas 75 05 8) dissolve in water?
Yes, acetonitrile Acn (CAS 75-05-8) is fully miscible with water in any ratio under normal conditions, making it a common solvent combination, particularly in high-performance liquid chromatography (HPLC), although adding salts or cooling can cause it to separate into different layers.
Acetonitrile is very soluble in water. It mixes with most organic solvents, e.g. alcohols, esters, acetone, ether, benzene, chloroform, carbon tetrachloride and many unsaturated hydrocarbons.

What is Acetonitrile Chemical Used for?
1. Acetonitrile liquid can undergo typical nitrile reactions and is used to prepare many typicalnitrogen-containing compounds. It is an important organic intermediate.
2. Acetonitrile Acn can be used as a solvent for the synthesis of vitamin A, cortisone, carboamine drugsand their intermediates, and as an active medium solvent for the manufacture of vitamin B1 andamino acids.
3. It can replace chlorinated solvent. It is used in vinyl coatings, fatty acid extractant, alcohol denaturant, butadiene extractant and solvent of acrylonitrile synthetic fiber. It is also used in fabric dyeing, lighting, perfume manufacturing and photosensitive material manufacturing.
