L-Lysine acetate salt is a versatile compound with several important applications, both in the field of medicine and beyond. L-Lysine acetate salt is used to treat genital and mouth lesions caused by the herpes simplex virus. It has been suggested that L-lysine supplementation may help reduce the frequency, duration, and severity of herpes outbreaks.
The invention discloses a preparation method of a bulk drug of lysine acetate and belongs to the field of amino acid preparation. The preparation method includes following steps: preparing lysine hydrochloride into a water solution, dechlorinating the water solution to obtain a high-purity lysine solution through an electrodialysis system, performing a reaction to the lysine solution with glacial acetic acid to obtain a lysine acetate water solution, and further nano-filtering, decoloring, ultra-filtering and concentrating and crystallizing the lysine acetate water solution to obtain the bulk drug of lysine acetate.
Single crystals of l-lysine acetate, an organic NLO material of the amino-carboxyl acid family, were successfully synthesized and grown by controlled evaporation technique.
