Acetonitrile/ACN Cas 75-05-8 is the simplest organic nitrile, usually also called methane cyanide and methyl nitrile, colorless transparent liquid at room temperature, highly volatile, with a special smell similar to ether, flammable, burning with a bright flame. Intersoluble with water, methanol, carbon tetrachloride, methyl acetate, ethyl acetate, dichloroethane and many unsaturated hydrocarbon solvents. Toxic, can be metabolized to hydrogen cyanide and thiocyanic acid. Acetonitrile is an important organic intermediate with excellent solvent properties. And widely used as extremely Chemicalbook aprotic solvent. Acetonitrile is the largest use as A solvent, can be used for the synthesis of vitamin A, cortisone, carbon amine drugs and intermediates of the solvent, but also for the production of vitamin B1 and amino acid active medium solvent. Can replace chlorinated solvent. It is used in vinyl coatings, fatty acid extractant, alcohol denaturing agent, butadiene extractant and solvent of acrylonitrile synthetic fiber. It also has many applications in fabric dyeing, lighting industry, spice manufacturing and photosensitive material manufacturing.

Acetonitrile production methods:

Acetonitrile production methods are many, including industrial production of acetic acid ammoniation, acetylene ammoniation and propylene ammoxidation by - product method.
1. Acetic acid ammonification method with acetic acid, ammonia as raw materials, under the action of aluminum oxide catalyst, at 360-420℃ temperature, reaction, one step synthesis acetonitrile, reaction liquid by water absorption and distillation to obtain the finished product. Raw material consumption quota: acetic acid (98%) 1763kg/t, liquid ammonia (99.5%) 691kg/t.
Acetylene ammoniation method acetylene, ammonia as Chemicalbook raw materials, with aluminum oxide catalyst, at 500-600℃ temperature, one step reaction synthesis acetonitrile. Raw material consumption quota: acetylene 10231m3, liquid ammonia (99.4%) 1007kg/t.
3 propylene ammonia oxidation byproduct method to propylene, ammonia and air as raw materials, through the catalyst synthesis of acrylonitrile, at the same time byproduct acetonitrile. Every ton of acrylonitrile by - product 25-100kg acetonitrile.
4. From acetamide and phosphorus pentoxide dehydration.
5. From dimethyl sulfate and sodium cyanide action.

At present, the main production method in the world is propylene ammoxidation by-product method, and the main acetonitrile output in China still comes from this method
At present, China's domestic market is unpredictable and the price of acetonitrile remains high. Please check the following figure for a better understanding.

In this special time,we still have the ability to meet the quantity of your request.

Since the Yuanfar engaged in acetonitrile export, the quality and price of its products are widely praised by customers abroad, The company will spare no effort to do a good job for customersabroad, for the development of customers to provide continuous power and support.
