摘要

HPLC was used to separate chiral compouds with chiral column. Another method was used in HPLC with chiral mobile phase additives to separate chiral compounds[1-3]. Using chiral mobile phase additives is a good way to separate the chiral compounds. The structure of the derivative takes an important role in separation. We derivatized 2-heptamine with benzene sulfonyl chloride and dansyl chloride, Using cyclodextrin derivatives as chiral mobile phase additives, 2-heptamine derivatives was separated by HPLC. 2-heptamine derivatives have a good absorbstance under 254nm. We separated these derivative with chiral mobile phase additives, the additives were 脽-CD, 2-O-(2,3-dihydroxypropyl)-脽-CD, 2-O-(hydroxypropyl)-脽-CD and so on. The additives are all highly hydro-soluble and good for separation. We used phosphoric buffer solution to supply proper pH range and ion intensity. A good separation result was obtained using 2-O-(hydroxypropyl)-脽-CD. It could be used in separation of molecule like aliphatic amine. Benzene sulfonyl chloride and dansyl chloride could be used to derivatize 2-heptamine for its chiral separation. And we got some conclusion about how to separate alkyl amine, and how to select the chiral mobile phase additives. We got a mechanism that the role chiral mobile phase additives played during the separation.
