Question

what is reduction of hydrogenated oil by catalyst

Answer 1

well , the hydrogenation is chemical process in which hydrogen is added to a organic compound. This is done to saturate the compounds . Hydrogenation process is largely used for the making of ghee from the vegetable oil in industries and in this process a catalyst "nickel" is used but the palladium and platinum also can be used as catalyst. This process occur at high temperature and makes the saturated compounds from the unsaturated one's.

Answer 2

1.The vegetable oils like ground nut oil are saturated hydrocarbons compounds containing double bonds.

2.They are in liquid state at room temperature.

3.Due to presence of double bonds vegetable oil undergoes addition reaction with Hydrogen to form saturated hydrocarbons called as vegetable Ghee or vanaspathi dalda which are solid at room temperature.

4.The reaction occurs in presence of catalyst Nickel.
