What is hydrogenation? What is its industrial application?

Text Solution

Verified by Experts

The addition of hydrogen to an unsaturated hydrocarbon to get a saturated hydrocarbon is called hydrogenation. This process takes place in the presence of nickel or palladium metals as catalyst.
It has an important industrial application. It is used to prepare vegetable ghee from vegetable oils. Vegetable oils such as groundnut oils, cottonseed oils and mustard oils are unsaturated and also contain double bonds (C=C). On hydrogenation (addition of hydrogen), in the presence of nickel as catalyst, vegetable oil produces vanaspati ghee.
