Question

what is catalytic hydrogenation of oils​

Answer 1

Answer:

Hydrogenation converts liquid vegetable oils into solid or semi-solid fats, such as those present in margarine. Changing the degree of saturation of the fat changes some important physical properties, such as the melting range, which is why liquid oils become semi-solid.

The catalyst used in hydrogenation of oils is nickel. It is used to speed up the reaction. Vegetable oils convert into vanaspati after hydrogenation.

Answer 2

Answer:

Catalytic hydrogenation is hydrogenation (adding hydrogen) of a compound with a double or triple bond. ... The process of catalytic hydrogenation utilizes a metal catalyst such as nickel, paladium or platinum. The mechanism begins by bonding hydrogen atoms to the metal through pressurized hydrogen gas.
