| Abstract |
Photodegradation experiments on crude oil surface films were carried out on natural sea water in an artificial marine system. The compositional changes in the surface film and the organic materials in the water below were investigated. The degradation products were isolated and analyzed. They were found to be primarily aromatic and aliphatic acids, and to a lesser extent alcohols, aldehydes and ketones with the same number of carbon atoms as the original hydrocarbons. A possible reaction scheme was developed based on the amounts and structures of these decomposition products, which were also used together with estimated rates of surface film photochemical decomposition, to suggest possible effects on the marine environment. |
