| Abstract | 1. Process for the preparation of D,L-carnitinamide chloride (I) see diagramm : EP0166901,P3,F1 characterized in that, in a first reaction stage, 2,3-epoxypropyltrimethylammonium chloride is reacted in aqueous solution with 0.8 to 2.0 equivalents of hydrocyanic acid at a pH above 7 and not above 11 and at a temperature between 20 and 100 degrees C, and the resulting nitrile is, without intermediate isolation and without addition of base, treated in the reaction solution with 1.5 to 5 equivalents of aqueous hydrogen peroxide at a temperature between 30 and 100 degrees C, and the reaction product is isolated in a manner known per se. |
