    Abstract: According to the new process, the hydrogenation of unsaturated fatty acid nitriles or mixtures of unsaturated and saturated fatty acid nitriles is carried out in the liquid phase in the presence of nickel catalysts or cobalt catalysts. In a first reaction step the fatty acid nitrile, in the presence of ammonia, is treated with hydrogenation hydrogen until all the nitrile groups are hydrogenated to predominantly primary amino groups. After the ammonia content in the reaction mixture obtained from the first step has been adjusted to a value of at most 0.1 mol of ammonia per mole of fatty acid nitrile used, a second reaction step is used to hydrogenate the double bonds present to saturated bonds. The desired primary and saturated fatty amine is obtained in a very high yield and has an iodine number of at most 5.

  • Patent number: 4605772
    Abstract: N-alkane-N-alkanolamines are prepared by (a) contacting an N-alkane-N-alkanolamine having more N-alkanolamine moieties than the product compound, with a haloalkane; (b) contacting the product of step (a) with a strong base; and (c) deprotonating the product of step (b). The method of the invention produces relatively pure compounds in high yield, from low-value starting materials. The compounds produced by the invention are useful for the absorption of sulfur compounds from gases produced by the combustion of sulfur-containing hydrocarbon materials.
