2-Butenenitrile

Description:

2-Butenenitrile, also known as 2-butenenitrile or methacrylonitrile, is an organic compound characterized by its alkenyl nitrile structure. It features a double bond between the second and third carbon atoms of a four-carbon chain, with a cyano group (-C≡N) attached to the terminal carbon. This compound is typically a colorless to pale yellow liquid with a distinctive odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water. 2-Butenenitrile is known for its reactivity, particularly in polymerization reactions, where it can serve as a monomer for producing various copolymers. It is also utilized in the synthesis of pharmaceuticals and agrochemicals. Due to its nitrile functional group, it can exhibit toxicity and should be handled with care, following appropriate safety protocols. Overall, 2-butenenitrile is an important intermediate in organic synthesis and materials science.

2-Butenenitrile

CAS: 4786-20-3

2-Butenenitrile is a reactive chemical that can be produced by the reaction of acetylene and hydrogen chloride. This chemical has two hydrogen atoms attached to a double bond. The activation energies for this reaction are -6.0 kcal/mol and -6.8 kcal/mol, which shows that the reaction is exothermic. The products of this reaction include crotononitrile, hydrochloric acid, and adiponitrile. The optimal conditions for this reaction are between 50 degrees Celsius and 60 degrees Celsius at atmospheric pressure with a mole ratio of 1:1:1 (acetylene:hydrogen chloride:water). 2-Butenenitrile also reacts with trifluoroacetic acid to produce hydroxyl group (-OH) and trifluoroacetic acid.
