Thiophene

            Thiophene is monocyclic heteroarene, furan, in which oxygen atoms are replaced by sulphur. It acts as a non-polar solvent. These are human organic heteromonocyclic brood stock, members of thiophene, monocyclic heteroarynx, and volatile organic compounds. Thiophene is a heterocyclic compound of the C4H4S formula. It consists of a flat and aromatic five-member ring, as shown by the breadth of substitution reaction. This is a colorless liquid with a smell similar to benzene. It is similar to benzene in most reactions. Compounds analogous to thiophene include furan (C4H4O), selenium furnace (C4H4Se) and pyrrole (C4H4NH), each of which varies depending on heteroatoms in the ring. Thiophene and especially its derivatives are found in petroleum, sometimes in concentrations of up to 1-3%. The thiophene content of oil and coal is removed by hydrodesulphurization (HDS). Thiophene undergoes hydrogenolysis to form hydrocarbons and hydrogen sulfide. Thiophene is a toxic, flammable, colourless liquid, insoluble in water. Thiophene rings are the building blocks most commonly used for conjugated polymer construction, mainly because of their high environmental resistance.
