How do you harden oil?
HydrogenationDuring hydrogenation, vegetable oils are hardened by reacting them with hydrogen gas at about 60ºC. A nickel catalyst is used to speed up the reaction. The double bonds in the vegetable oils are converted into single bonds. This is the way unsaturated fats can be made into saturated fats.
What is the process used to turn liquid oils into more highly saturated solid fats?
Hydrogenation .
The reaction of hydrogen H2 and propene using a platinum catalyst is called?
An addition reaction, specifically it is called hydrogenation.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Uses of magnesium silicate?
Magnesium silicate may be used as a purifying absorbent in dry cleaning and animal and vegetable oils. It is also used as a filler paper, ceramics, and glass. It may also serve as an anti-caking agent and catalyst.
Can pt and pd be used in the hydrogenation of alkenes?
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
What is the process of fat hydrogenation?
The process of fat hydrogenation involves a high temperature and the involvement of a metallic catalyst. The metallic catalyst either increases or decreases the number of the chemical bonds within the molecules of the substances.

How can you use the word hydrogenation in a sentence?
Margarine is produced by the hydrogenation of vegetable oils.
What process is used to convert polyunsaturated oils into saturated fats?
olive and canola oils are examples of saturated fats
What is the process used to turn liquid oils into more highly saturated solid fats?
Hydrogenation .
Which is the gas that is used for converting vegetable oils into saturated fats?
Hydrogen. The process is called hydrogenation.
When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
What process is used to turn liquid oils into more highly saturated solid fats?
This process is hydrogenation.
Is margarine made from plastic?
No. It is made by the hydrogenation of oils or fats.
What is the chemical name for the process hardening vegetables oils?
Hydrogenation
