Moreover, alcohols undergo oxidation reactions to produce ketones, aldehydes or carboxylic compounds for example, if primary alcohols are oxidized with acidified potassium dichromate they would produce an aldehyde.
E6 acid value 1 introduction the acid value (av) is a common parameter in the specification of fats and oils it is defined as the weight of koh in mg needed to neutralize the organic acids present in 1g of fat and it is a measure of the free fatty acids (ffa) in a sample of oil or fat indicates hydrolysis of triglycerides. In lab-scale tests, chemical oxidation has been shown to be effective for chlorinated organics [6, p 229] this bulletin provides information on the technology appli- cability, limitations, a technology description, the types of re- siduals produced, site requirements, current performance data, status of the technology, and sources of further.
