What is transmission hydrogenation?

Transmission hydrogenation indicates treatment of an element or hydrogen compound from a source other than gas hydrogen. The chemical reaction occurs between the substance to be modified and the molecular hydrogen in the presence of catalysts to facilitate the reaction. This process is often used in industrial processing of organic, carbon compounds. For example, coal liquefaction involves extensive use of transmission hydrogenation to produce synthetic fuels from coal.

The chemical reaction basically involves adding pairs of hydrogen atoms to the treated material. In the hydrogenation of transmission, this is done using donor solvents as a source of hydrogen. The common solvents of the donor include formic acid and isopropyl alcohol, although some are synthesized for use in a particular transmission process. The reaction usually occurs in the presence of a metal catalyst, which reduces the minimum energy needed to start the reaction.

transmission hydrogenation is particularly useful in organic synthesis, PRSurvival of carbon compounds by organic reactions. For use in this process, organizer catalysts based on a metal group of platinum have been developed. Isopropyl alcohol is often a donor solvent and becomes acetone after hydrogen contribution. The catalysts themselves are unchanged by the reaction.

The

hydrogenation of organocatalytic transmission uses non -metallic catalysts. These are made of elements common to organic compounds such as carbon, sulfur and hydrogen. The development of these catalysts allows you to apply the transmission process to a wider range of chemicals. The most commonly used metal catalysts are ineffective for hydrogenation of organic groups such as a series of benzene. This chemical class plays an important role in the production of drugs, plastics and dyes.

Hydrogenation of uninvited donors has long been a standard laboratory procedure. Research on the process of hydrogenation of transmission was motivated by its importance forPharmaceutical and petrochemical industry. The development of hydrogen and catalyst donors for use with substances that are not suitable for traditional transmission processing is an area of ​​interest. Research on conventional metal catalysts, such as a nickel, instead of platinum and other rare metals, seeks to increase the more cost -effective industrial process.

The use of the hydrogen non -landing donor has several advantages when implementing a large scale. Usually, standard industrial equipment can be used in a transmission process rather than in a pressure device necessary when using gas. The deceased gas is also extremely flammable and requires great care in storage and handling. Thanks to these considerations, the use of hydrogen in gas is much more expensive than the use of non -dormant hydrogen donors.
