| titleOfInvention | Process for the production of lightly-coloured primary fatty amines |
| abstract | The invention relates to a process for the preparation of light-colored, primary fatty amines obtained by hydrogenation of saturated and / or unsaturated fatty acid nitriles based on animal and / or vegetable fatty acids having a chain length of 8 to 22 carbon atoms and theillaborative working up of the obtained Hydrierproduktes are produced, and their derivatives,n n n Based on the disadvantages of the known prior art, it is an object to provide an economical, easy to carry out process for the preparation of primary, saturated and / or unsaturated fatty amines with high color stability. Furthermore, the fatty amines should be suitable for producing light-colored secondary products.n n n As a solution it is proposed that phosphonic and / or phosphinic acid and / or salts thereof, individually or as a mixture, is added to the hydrogenation product before the work-up by distillation, preferably in an amount of from 0.01 to 5%, based on the amount hydrogenation product, wherein the additive is used in solid form or as an aqueous solution.n n n The addition of the additive gives the distillates fatty amine qualities which have significantly lower APHA color values than the corresponding untreated fatty amines. Even under thermal stress or during a longer interim storage of the treated fatty amine, there is only a slight increase in the APHA color number. |
