What is hydrogenation?

Solution

Addition of hydrogen to unsaturated hydrocarbons in presence of a catalyst such as nickel or palladium to form saturated hydrocarbons is called hydrogenation.
The process of hydrogenation is used in industry to convert vegetable oils to vanaspatighee.

Hydrogenation is an addition reaction where hydrogen molecules are used to saturate organic compounds. This process is effective under certain catalytic conditions and controlled temperatures depending on the type of hydrocarbon. This process aims to convert the pi bonds into sigma bonds, which are stronger, and make them solid under atmospheric temperature.

Hydrogenation is used in the oil industry in making trans fats or margarine by increasing the melting point through reducing the carbon-to-carbon double bonds. The oil industry suffers from hydrogenation corrosion, which occurs in components that host gaseous hydrogen compounds at high temperatures.
