Chemical Properties of E85. Ethanol is the major component of E85. Ethanol, C2H6O, is ethane with a hydrogen molecule substituted by a hydroxil radical. It is colorless, flammable and a moderately toxic chemical compound that has a unique, perfume-like smell.thanol, before it was used as a main alcoholic drink ingredient, is usually produced through fermentation -- the carbohydrates' presence by specific yeast species when oxygen is not available. Ethanol is deemed as a depressant and a psychoactive drug component of liquors.
Biochemical oxygen demand (BOD) is the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. The term also refers to a chemical procedure for determining this amount.
The BOD test measures the amount of oxygen neededto biologically oxidize material in wastewater. Because the rate of biological activitydepends on temperature and complete stabilization may require as long as 20 days, theBOD 5 test has been standardized to conditions of 20Â°C for five days.lternatively, use a factor of 80 mL/mgd. For example, at a flow of 4.1 mgd,the sample volume to be collected is 4.1 mgd 80 mL/mgd 328 mL. 17-26 Operation of Municipal Wastewater Treatment Plants Copyright Â© 2007 Water Environment Federation.
