hydrogenation reaction

Hydrogenation – meaning to treat with hydrogen – 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

hydrogenation in solution

An alternative hydrogenation method is the low-temperature electrocatalytic process which has made possible the hydrogenation of edible liquid oils with a final content of less than 6% TFA (Pintauro 1993) More recent methods include the partial hydrogenation process of liquid oils in which a solution of oil and solvent are brought to the

Hydrogenation

Hydrogenation involves the reaction between unsaturated liquid oil and hydrogen adsorbed on a metal catalyst The oil is mixed with a suitable catalyst (usually nickel) heated (140–225C) then exposed while stirred to hydrogen at pressures up to 60 psi (Nawar 1996)

Hydrogenation Methods

2011-1-1Variability in Natural Fats and Oils One can say the simplest—and indeed superficial—view of the hydrogenation of oils is the progressive addition of hydrogen at double bonds pursued far enough to produce more and more saturated groups within the triglycerides until the texture at ambient temperature becomes firmer ultimately hard and even brittle
