A method of making an amino acid triisocyanate is provided, the method comprising reacting an amino acid trihydrochloride with phosgene to form the amino acid triisocyanate. In some embodiments, the amino acid trihydrochloride comprises lysine ester trihydrochloride salt and the amino acid triisocyanate comprises lysine ester triisocyanate. In some embodiments, there is a lysine ester triisocyanate having a purity of at least about 98%, the lysine ester triisocyanate having a structure resulting from reacting lysine ester trihydrochloride salt with phosgene to form the lysine ester triisocyanate. These lysine ester triisocyanates can be used to make biodegradable polyurethanes.
提供了一种制备氨基酸三异氰酸酯的方法,该方法包括将氨基酸三氢氯酸盐与光气反应以形成氨基酸三异氰酸酯。在一些实施例中,氨基酸三氢氯酸盐包括赖氨酸酯三氢氯酸盐,而氨基酸三异氰酸酯包括赖氨酸酯三异氰酸酯。在一些实施例中,存在一种纯度至少约为98%的赖氨酸酯三异氰酸酯,该赖氨酸酯三异氰酸酯具有由赖氨酸酯三氢氯酸盐与光气反应形成赖氨酸酯三异氰酸酯的结构。这些赖氨酸酯三异氰酸酯可用于制造生物降解聚氨酯。
