| titleOfInvention | Preparation method of L-homoarginine hydrochloride |
| abstract | The invention relates to the technical field of chemical raw material production, and particularly discloses a preparation method of L-homoarginine hydrochloride. The preparation method of L-homoarginine hydrochloride provided by the invention comprises the steps of: based on L-lysine as a starting raw material, firstly reacting L-lysine with copper chloride dihydrate to generate di-lysine copper complex to protect alpha-NH2, further carrying out carbamide treatment on omega-NH2 to obtain di-homoarginine copper complex, and then carrying out decopperization, impurity removal and acidification to obtain end product L-homoarginine hydrochloride. The preparation method of L-homoarginine hydrochloride provided by the invention is mild in reaction conditions, simple in operation, low in production cost and high in product purity, and is suitable for industrial production. |
