In some embodiments, a method of making an amino acid trihydrochloride is provided, the method comprising reacting an amino acid monohydrochloride with an alkanolamine to form the amino acid trihydrochloride. In some embodiments, the amino acid monohydrochloride comprises lysine hydrochloride, which is mixed with ethanolamine to form lysine ester trihydrochloride. In some embodiments, there is a lysine ester trihydrochloride salt having a purity of at least about 98%, the lysine ester trihydrochloride salt having a structure resulting from reacting lysine hydrochloride and ethanolamine to form the lysine ester trihydrochloride salt. The lysine ester trihydrochloride can be made in one reaction vessel.
在某些实施例中,提供了一种制备氨基酸三氢氯化物的方法,该方法包括将氨基酸单氢氯化物与烷醇胺反应以形成氨基酸三氢氯化物。在某些实施例中,氨基酸单氢氯化物包括赖氨酸盐酸盐,其与乙醇胺混合以形成赖氨酸酯三氢氯化物。在某些实施例中,存在一种纯度至少约98%的赖氨酸酯三氢氯化物盐,该赖氨酸酯三氢氯化物盐具有由赖氨酸盐酸盐和乙醇胺反应形成赖氨酸酯三氢氯化物盐的结构。赖氨酸酯三氢氯化物可以在一个反应容器中制造。
