Petrochemicals from Renewable Resources

This example describes making alpha-olefins from car-boxylic acids.

A catalytic technique (the Henkel process) offers a green alternative for making alpha-olefins because it can produce them from fatty acids instead of from petroleum. In the reaction, an equimolar mixture of a carboxylic acid and acetic anhydride is heated to 250°C in the presence of a palladium or rhodium catalyst as follows:

This reaction causes the carboxylic acid to undergo de-carbonylation and dehydration to a 1-alkene having one
