Procedure

12 grams of L-lysine monohydrate is dissolved in 20 ml of water to which 6.0 ml of concentrated hydrochloric acid has been added. 2.964 grams of disodium succinate is added to neutralize some of the excess hydrochloric acid and 2.16 grams of succinic acid are added with mixing until effervescence ceases and all solids are dissolved. The solution is dried in a 110° C. oven until solids begin to form when cooled to room temperature. After 15 to 30 minutes solids form and are collected.
