  • This study was performed to measure the elimination effects of chlorine dioxide on phenol compounds, trihalomethanes (THMs) and algae in drinking water supply. The raw and chlorinated water were treated with 0.5ppm of chlorine dioxide. The phenols contained 0.052mg/1, 0.019mg/1 of raw and treatedwater was absolutely destroyed. The THMs was reduced to 50-60% of the concentration and the algae was inhibited to about 50% of the growth.

  • The alkylphenols, chlorophenols and bisphenol A were determined by gas chromatography/mass spectrometry-selected ion monitoring (GC/MS-SIM) mode followed by two work-up methods for comparison; isoBOC derivatization method and TBDMS derivatization method. Eleven phenols in paper samples were extracted with acetonitrile. (omitted)

  • The alkylphenols, chlorophenols and bisphenol A were determined by gas chromatography/mass spectrometry-selected ion monitoring mode followed by three work-up methods for comparison: EPA method, isoBOC derivatization method and TBDMS derivatization method. Eleven phenols in water samples were extracted with dichloromethane. (omitted)

  • Nine cinmetacin derivatives as potential nonsteroidal analgesic and antiinflammatory compounds were prepared and their analgesic-antiinflammatory activity was compared with cinmetacin. Salicylic acid and phenols were reacted with dicyclohexyl carbodiimide (DCC) to give phenol salicylates (1-4). Cinmetacin was treated with DCC and phenol derivatives to yield cinmetacin esters (5-13). Compounds (5, 7, 8, 10, 12, and 13) showed stronger analgesic activity than cinmetacin, but only compound (5) showed comparable antiinflammatory activity to cinmetacin.
