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.

Hydrogenation The industrial importance of the hydrogenation process dates from 1897, when the French chemist Paul Sabatier discovered that the introduction of a trace of nickel as a catalyst facilitated the addition of hydrogen to molecules of carbon compounds.

- It was the hydrogenation process of producing synthetic gasoline and iso-octane properties in gasoline that enabled Germany to go to war in 1940  and this hydrogenation process was developed and financed by the Standard Oil laboratories in the United States in partnership with I.G. Farben.

Methylation In the chemical sciences, methylation denotes the addition of a methyl group to a substrate or the substitution of an atom or group by a methyl group.Methylation is a form of alkylation with a methyl group, rather than a larger carbon chain, replacing a hydrogen atom.n biological systems, methylation is catalyzed by enzymes; such methylation can be involved in modification of heavy metals, regulation of gene expression, regulation of protein function, and RNA processing. Methylation of heavy metals can also occur outside of biological systems.

Methylation In the chemical sciences, methylation denotes the addition of a methyl group to a substrate or the substitution of an atom or group by a methyl group.Methylation is a form of alkylation with a methyl group, rather than a larger carbon chain, replacing a hydrogen atom.NA methylation in vertebrates typically occurs at CpG sites (cytosine-phosphate-guanine sites, that is, where a cytosine is directly followed by a guanine in the DNA sequence). This methylation results in the conversion of the cytosine to 5-methylcytosine.

When is a vegetable oil not a vegetable oil? When it's a plastic! Hydrogenation is the chemical name for the addition of hydrogen to an existing molecule, usually an organic molecule which has a doubl-bond between two carbon atoms. That bond is broken and a hydrogen atom binds to each of the free bonds on adjacent carbon atoms. H2C=CH2 becomes H3C-CH3.

Methylation From Wikipedia, the free encyclopedia. In the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. Methylation is a form of alkylation, with a methyl group, rather than a larger carbon chain, replacing a hydrogen atom.

Soybean Oil Health Concerns Hydrogenated Soybean Oil. Hydrogenating soybean oil stabilizes it and allows it to thicken to a solid form. This is one oil found in margarine products. Once the oil solidifies, it can present some health risks. Hydrogenation reduces the amount of polyunsaturated fats and adds trans fats to the formula. Trans fats are associated with heart disease and plaque buildup in arteries. The process to create solid soybean oil reduces the nutritional value of the plant.

- Types [edit]. Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both substance and water molecule to split into two parts. In such reactions, one fragment of the target molecule (or parent molecule) gains a hydrogen ion.t is the hydrolysis of a triglyceride (fat) with an aqueous base such as sodium hydroxide (NaOH). During the process, glycerol is formed, and the fatty acids react with the base, converting them to salts.

Sore Throats Irritation caused by dry heat, a chronic stuffy nose, pollutants and chemicals, and straining your voice can also irritate your throat. Reflux, or a regurgitation of stomach acids up into the back of the throat, can cause you to wake up with a sore throat. Tumors of the throat, tongue, and larynx (voice box) can cause a sore throat with pain radiating to the ear and/or difficulty swallowing. Other important symptoms can include hoarseness, noisy breathing, a lump in the neck, unexplained weight loss, and/or spitting up blood in the saliva or phlegm.

Hydrogenation Hydrogenation – to treat with hydrogen – is a chemical reaction between molecular hydrogen 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 ...

Eating a Diet Low in Saturated Fat, Trans Fat, and Cholesterol The process of hydrogenation involves adding hydrogen thereby changing the chemical make-up of the oil (it changes a liquid oil, naturally high in unsaturated fatty acids, to a more solid and more saturated form. The greater the degree of hydrogenation, the more saturated the fat becomes).

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.arbonization is also a stage in the charcoal making process, and is considered the most important step of all since it has such power to influence the whole process from the growing tree to the final distribution of charcoal to various sources.

What is Hydrolysis? Hydrolysis. Hydrolysis is a chemical reaction or process in which a chemical compound is broken down by reaction with water. This is the type of reaction that is used to break down polymers.Water is added in this reaction.he addition of a molecule of water to a chemical compound, without forming any other products is usually known as hydration, rather than hydrolysis. In biochemistry, hydrolysis is considered the reverse or opposite of dehydration synthesis.
