Degradation of the petroleum component's monomethylbenzothiophenes on exposure to light
Bobinger, Stefan,Andersson, Jan T.
, p. 2569 - 2579 (1998)
The photochemical degradation of monomethylated benzo[b]thiophenes in aqueous solution was studied to elucidate the fate of crude oil components after an oil spill. One principal reaction pathway involves oxidation of the methyl group(s) to the carboxylic
