Hydrogenation Hydrogenation – to treat with hydrogen – is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures.

Definitions &Translations Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram.

Healthy eating guide Hydrogenation is the process that turns liquid oil into a more solid fat. Liquid oils are ‘hardened’ by adding hydrogen to stabilise the fat, making it easier to use in recipes for biscuits, cakes, pastry, and other processed foods.You can tell how ‘saturated’ a fat is by its texture at room temperature.ome evidence suggests that the effects of these trans fats may be worse than saturated fats. So, as part of a healthy diet we should try to reduce the amount of foods we eat that contain hydrogenated or saturated fats and replace them with unsaturated fats.

Hydrogenation Definition Hydrogenation Definition: Hydrogenation is a reduction reaction which results in an addition of hydrogen (usually as H2). If an organic compound is hydrogenated, it becomes more 'saturated'. Hydrogenation has many applications, but most people are familiar with the reaction as the one used to make liquid oils into semi-solid and solid fats.

Carbonization Carbonization (or carbonisation) is the term for the conversion of an organic substance into carbon or a carbon-containing residue through pyrolysis or destructive distillation.his carbonization, which can also be seen as a spontaneous breakdown of the wood, continues until only the carbonised residue called charcoal remains. Unless further external heat is provided, the process stops and the temperature reaches a maximum of about 400°C.

Hydrolysis Generally, hydrolysis or saccharification is a step in the degradation of a substance. Hydrolysis can be the reverse of a condensation reaction in which two molecules join together into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water.

Soda pop is basically sugar water with a little bit of flavoring and added carbonation.carbonation (Noun). The amount or level of dissolved carbon dioxide remaining in solution.he process usually involves carbon dioxide under high pressure. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which causes the solution to fizz. This effect is seen in carbonated soft drinks.

What is Hydrogenation? Hydrogenation is a chemical process in which hydrogen gas is bubbled through a liquid oil in the presence of a catalyst, often a reactive metal such as platinum or nickel. The resulting reaction forces unsaturated fatty acids to accept additional hydrogen atoms and become at least partially saturated.
