L-Aspartic Acid → HCID 9837063, compound

Participants

Reaction Steps

20 g of zinc carbonate (zinc content: 32%) was dispersed in 500 ml of water and dissolved therein by stirring, and 60 g of aspartic acid was added thereto to perform a reaction, then the solution was continually stirred until the zinc carbonate and aspartic acid were entirely dissolved. Bubbles were generated in the initial stage of the reaction but they disappeared after a certain time. The resulting reaction solution was centrifuged to remove insoluble materials, and the clear supernatant was separated. The supernatant was freeze-died to obtain about 72 g of zinc-aspartic acid chelate.
