thiophene usage and synthesis |
chemical properties | colourless to pale yellow liquid |
usage | thiophene is used as a building block of various organic molecules and pharmaceuticals providing functional properties. |
general description | a colorless liquid with an unpleasant odor. insoluble in water and slightly denser than water. flash point 30°f. vapors heavier than air. irritates the skin, eyes, and mucous membranes. used to make pharmaceuticals and dyes. |
air & water reactions | highly flammable. insoluble in water. |
reactivity profile | thiophene reacts violently with strong oxidizing agents and concentrated nitric acid causing fire and explosion hazards [handling chemicals safely 1980. p. 899]. a mixture of thiophene and n-nitrosoacetanilide exploded at 0°c [ber., 1887, 30, 367]. |
health hazard | may cause toxic effects if inhaled or absorbed through skin. inhalation or contact with material may irritate or burn skin and eyes. fire will produce irritating, corrosive and/or toxic gases. vapors may cause dizziness or suffocation. runoff from fire control or dilution water may cause pollution. |
fire hazard | highly flammable: will be easily ignited by heat, sparks or flames. vapors may form explosive mixtures with air. vapors may travel to source of ignition and flash back. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapor explosion hazard indoors, outdoors or in sewers. runoff to sewer may create fire or explosion hazard. containers may explode when heated. many liquids are lighter than water. |
