Dehydration of Alcohols

Dehydration of Alcohols Reaction type: 1 2- or β-Elimination Summary When heated with strong acids catalysts (most commonly H 2 SO 4 H 3 PO 4) alcohols typically undergo a 1 2-elimination reactions to generate an alkene and water Also known as dehydration since it involves the removal of a molecule of water Alcohol relative reactivity order : 3 o 2 o 1 o

9 8: Dehydration of Alcohols to Alkenes

Mechanism for the Dehydration of Alcohol into Alkene Different types of alcohols may dehydrate through a slightly different mechanism pathway However the general idea behind each dehydration reaction is that the –OH group in the alcohol donates two electrons to H + from the acid reagent forming an alkyloxonium ion

Definition of Chemical Reactions Of Alcohols

Dehydration is a chemical process of removing water from the molecule In the presence of strong acid alcohol undergoes dehydration to yield the alkene Dehydration may also refer as elimination reaction In the dehydration reaction -OH and -H are eliminated from the adjacent carbon atoms in the given alcohol to yield the alkene and water (H

Products from Oil Ethanol - Dehydration Why is Ethanol Dehydrated? Ethanol can be dehydrated to make ethene This reaction is the reverse of the hydration of ethene Ethanol gas (vapour) is passed over a hot aluminium oxide catalyst ethanol ethene + water C 2 H 5 OH (l) C 2 H 4 (g) + H 2 O (l) Ethene can also be made by cracking hydrocarbons
