Petroleum products consist mainly of aliphatics, aromatics, asphaltenes and resins. After oil exploitation, the concentrations resins are high in reservoirs; however, they also petroleum pollutants most recalcitrant to degradation, leading viscosity. A sizable amount work has been dedicated understand degradation mechanisms aliphatics aromatics; comparison, little carried out on asphaltene resi...
The uses of 3-formylbenzoic acid and 4-formylbenzoic acid as molecular probes along with previous and new transketolase mutants revealed the factors governing the rate of reaction between transketolase and aromatic aldehydes. The novel α,α-dihydroxyketones were produced at 15 to 30-fold higher yields and up to 250-fold higher specific activities with D469T TK when compared to those obtained for...
The photostability of aromatic compounds in the presence of air is significantly improved through perfluoroalkylation of the corresponding aromatic cores and use of polyfluorinated solvents despite higher O(2) concentration in polyfluorinated solvents than in hydrocarbon solvents.
