Sabatier-Senderens

SABATIER-SENDERENS REDUCTION. Catalytic hydrogenation of organic compounds in the vapor phase by passage over hot, finely divided nickel (the oldest of all hydrogenation methods). 

The use of nickel as a catalyst has been investigated by Ipatiew, Sabatier, Senderens, Maillie and many others. According to Mailhe the conversion of alcohols into aldehydes and hydrogen must he regarded as a reversible process in the presence of nickel catalyst,... 

Z-Menthone can be made by the oxidation of rhodinol with a chromic-sulphuric acid mixture.1 A Sabatier-Senderens reduction of thymol gives a mixture containing 30 per cent menthone.2 Z-Menthone is also obtained by treating menthol with copper at 3000.3 The method used in these directions is that of Beckmann.4... 

Sabatier-Senderens process A method of hydrogenating unsaturated vegetable oils to make margarine, using hydrogen and a nickel catalyst. It is named for the French chemists Paul Sabatier (1854-1941) and Jean-Baptiste Senderens (1856-1937). See also hardening. 

In terms of hydrogenation, the Sabatier-Senderens reduction has been extensively modified, as shown by the Fischer-Tropsch Synthesis (or process), the Adkins Catalyst, and Raney-Nickel Catalyst. In addition, the silica black-supported nickel catalyst, and nickel-based complex reducing agents (Nic, e.g. NaH-RONa-Ni(OAc)2), have also been developed, the latter is a heterogeneous hydrogenation catalyst that works at atmospheric pressure.

Sabatier-Senderens process A process for the hydrogenation of an organic compound such as an unsamrated fat and used to produce margarine. It uses hydrogen gas and a nickel catalyst at around 150 C. The process Is named after 1912 Nobel Prize wiimer Paul Sabatier (1854- 1941)and lean-Baptiste Senderens (1856 1937).
