Embodiment Construction
[0008] The novel reagent used for amino acid enantiomer separation described in the present invention is prepared by the following method: chiral molecule D-dibenzoyl tartaric acid or L-dibenzoyl tartaric acid with a molar concentration ratio of 1:1 to 40 and dibenzoyl tartaric acid (2-Hexylhexyl)phosphoric acid is mixed, diluent n-octanol is added thereto, and after stirring, unreacted chiral molecules containing D-dibenzoyl tartaric acid or L-dibenzoyl tartaric acid, di(2-hexyl tartaric acid, Base hexyl) phosphoric acid, and the mixed solution system that reacts to form a chiral intermediate complex, and the prepared mixed solution system is a new reagent for the separation of amino acid enantiomers.
[0009] The present invention will be described below in conjunction with specific embodiments.
