| titleOfInvention | Process for preparing very pure L-lysine base |
| abstract | A process for the preparation of a very pure L-lysine base from L-lysine hydrochloride, which comprises adding to the aqueous alkali solution, in particular NaOH, a stoichiometric concentration of 10 to 50% by weight, preferably 20 to 30% by weight. the amount of L-lysine hydrochloride at 20 to 80 ° C, preferably 40 to 60 ° C, and then the solution obtained is cooled to room temperature and subjected to electrodialytic desalination carried out in a multiple discontinuous arrangement with alternating variation solution in the diluate and concentrate branches, the salt concentration being lower than 0.01% by weight. while increasing the L-lysine base concentration, the desalted L-lysine base solution is either used directly or concentrated in vacuo or the L-lysine base is crystallized after vacuum distillation of the water. It is also possible to cool the aqueous solution of alkali during the addition of the stoichiometric amount of L-lysine hydrochloride to a temperature of less than 30 [deg.]. |
