Title: An improved process for the selective hydrogenation of polyolefines to more saturated products
Inventor: WIESE HERBERT KARL
IPC: C07C5/05
Filed: 1961-03-22
Abstract: Cyclic trienes or dienes are hydrogenated to more saturated cyclic olefins in the liquid phase by reaction with hydrogen at 15 DEG -100 DEG C. in the presence of a hydrogenation catalyst and a C2-C20 primary or secondary alcohol.  The catalyst may be Raney nickel or supported nickel, iron, cobalt, palladium, platinum, molybdenum, tungsten or chromium or oxide or sulphide thereof.  The alcohol is used in amounts of 0,1-10 mols. per mol. of cyclic olefin.  Hydrogen is added pure or mixed with low molecular weight hydrocarbons or nitrogen at a partial pressure of 0,1-10 atmospheres, the total pressure being 0,1-100 atmospheres.  In a preferred embodiment the hydrogenation is effected in two stages, the first using 65-90% of the stoichiometric amount of hydrogen and effecting the second stage in the absence of hydrogen, the alcohol being converted to aldehyde or ketone.  The conversions of cyclododecatriene to cyclododecene and of cyclooctadiene to cyclooctene are exemplified.
