The desirable (left) and undesirable pathways for partial hydrogenation of an unsaturated fat. Elaidic acid is a trans fat with negative health effects. Full hydrogenation results in the conversion of all of the unsaturated fats into saturated fats by transforming all of the double bonds in the fat into single bonds.
The production of hydrotreated vegetable oils is based on introducing hydrogen molecules into the raw fat or oil molecule. This process is associated with the reduction of the carbon compound. When hydrogen is used to react with triglycerides, different types of reactions can occur, and different resultant products are combined. [1]
Hydrogenation is a chemical reaction between molecular hydrogen (H 2) 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 ...
As the degree of saturation is raised by full or partial hydrogenation, the oil's viscosity and melting point increase. While full hydrogenation produces largely saturated fatty acids, partial hydrogenation results in the transformation of unsaturated cis fatty acids to unsaturated trans fatty acids in the oil mixture due to the heat used in ...

Fat hydrogenation, combining vegetable oil with hydrogen to make it more saturated; Edible oil refining, process to refin a raw oil to produce an edible oil, which differ from Olive oil production. Biodiesel production by transesterification; Production of hydrotreated vegetable oil, a biofuel
In the 1930s catalytic hydrogenation was commercialized, which allowed the conversion of fatty acid esters, typically tallow, to the alcohols. In the 1940s and 1950s, petrochemicals became an important source of chemicals, and Karl Ziegler had discovered the polymerization of ethylene. These two developments opened the way to synthetic fatty ...
The fatty acid or fatty esters are susceptible to hydrogenation converts unsaturated fatty acids into saturated fatty acids. [1] The acids or esters can also be reduced to the fatty alcohols. For some applications, fatty acids are converted to fatty nitriles. Hydrogenated of these nitriles gives fatty amines, which have a variety of ...
