3-Methylthiophene Chemical Properties,Usage,Production
Chemical Properties
clear colorless to light yellow liquid
Uses
A thiophene derivative used as an electropolymerization monomer in conducting polymer research.
Uses
Conducting polymer precursor.1
Uses
Thiophene, 2-methyIthiopheney and 3-methylthiophene act as inhibitors for the polymerization of trichloroethylene in a solvent used for the degreasing of iron and aluminum, said polymerization being catalyzed by contact of the solvent with the metals. Bonz, in 1885, reported the formation of a dichloroethylthiophene from chlorination of 2-ethylthiophene in the cold. Is Opolski studied the chlorination of 2- and 3-methylthiophenes, 2-ethyl- and 2-butylthiophene and reported constants for the monochloro derivatives. Voerman has chlorinated 3-methylthiophene in the side chain with phosphorus trichloride in the sunlight, but concurrent ring chlorination predominates. 3-Methylthiophene gives a unique reaction with alkyl- or arylsodium in which the substitution takes place exclusively in the 5-position rather than in the expected 2-position.
Uses
3-Methylthiophene is found in coffee and coffee products. it is a maillard product, present in roast coffee aroma.
3-Methylthiophene is a member of thiophenes. Conducting polymer precursor. Copolymerization of 3-alkylthiophene and 3-methylthiophene is a promising approach to provide a polymer which has both solution processible property and high electrical conductivity.
Definition
ChEBI: 3-Methylthiophene is a member of thiophenes.
Purification Methods
Dry it with Na2SO4, then distil it from sodium. [Beilstein 17 III/IV 277, 17/1 V 331.]
