reaction of alcohol with k2cr2o7 and h2so4 number

dehydration of alcohols

Dehydration of alcohols using an acid catalyst The acid catalysts normally used are either concentrated sulphuric acid or concentrated phosphoric(V) acid H 3 PO 4 Concentrated sulphuric acid produces messy results Not only is it an acid but it is also a strong oxidising agent It oxidises some of the alcohol to carbon dioxide and at the same time is reduced itself to

Oxidation of primary alcohols to carboxylic acids

For the reaction to proceed efficiently the alcohol must be at least partially dissolved in the aqueous solution This can be facilitated by the addition of an organic co-solvent such as dioxane pyridine acetone or t-BuOH KMnO 4 will readily react with a carbon-carbon double bond before oxidizing a primary alcohol Normally these oxidations are performed under strong basic
