A method for the production of saturated prima of 5-sulfopropoxyisophthalic acid, fatty amines by hydrogenation of the corresponding unsaturated fatty amines of 5-sulfopropoxyisophthalic prima preferential aet

摘要

the new procedure is the hydrogenation of double bonds in unsaturated primary fettamin in the way that the unsaturated primary fettamin in liquid phase and in the presence of 0.1 to 10 wt.% nickel or cobalt catalyst with hydrogen at a temperature of 8 0 to 160u00b0c and a pressure of 1 to 40 bar is implemented.when the hydrierende fettamin ammonia, there in front of the hydriervorgang largely removed.
