## Abstract The production of ethanol by fermentation and subsequent distillation generates wastewater known as ‘vinasse’. This waste is highly polluting on account of its high organic load and antibacterial activity—which arises from the presence of phenolic compounds that reduce the efficiency of

The oxidation mechanism of aldehydes with permanganate was studied in acidic and alkaline media on acetaldehyde, propionaldehyde, pivalaldehyde (2,2Ј-dimethylpropanal) and chloral substrates. On addition of water to acetaldehyde dissolved in organic solvents the rate increased, and therefore it may
