Description
Technical field
The present invention relates to a kind of preparation method of chiral stationary phase, is that a kind of bonding-affinity composite type polysaccharides chiral fixedly is combined to method specifically.
Background technology
Over nearly 20 years, the chiral structure compound is one of research focus of pharmacology and analytical chemistry always, the chiral resolution of enantiomter is the effective means that obtains the optical voidness material, and chiral chromatogram particularly chiral high performance liquid chromatography is the chiral separation method that develops rapidly in recent years.The core of chiral chromatogram is chiral stationary phase (CSPs), and it is strong therefore to design and develop recognition capability, and load capacity is big, and the CSPs of applied range is the research forward position of chiral chromatogram always.In at present a large amount of chiral stationary phases, the fixing purposes widely that has been proved to be mutually of polysaccharides chiral.Chiral stationary phase with the preparation of polysaccharide derivates such as cellulose, starch has the ability that splits preferably, is one of most popular chiral stationary phase in the high performance liquid chromatography chiral resolution.
Commercial polysaccharide derivates is fixing to be to adopt the physics coating process that polysaccharide derivates is fixed on the chromatography matrix mutually, but it is not firm that physics applies its adhesion, the phase range of choice that flows is little, causes shortcomings such as the solubility of chiral material in flowing mutually is low, has limited its application.Also have in addition polysaccharide derivates is fixed on the chromatography matrix through chemical bonding, though the method has improved the fixedly solvent resistance of phase, but because of having reduced the orderly arrangement of polysaccharide derivates, the fractionation ability all is lower than coating-type chiral stationary phase (Tomoyuki Ikai, Chiyo Yamamoto, Masami Kamigaito, Yoshio Okamoto., 2007,1157:151-158.Bezhan Chankvetadze, Tomoyuki Ikai, Chiyo Yamamoto, Yoshio Okamoto..Journal ofChromatography A, 2004,1042:55-60.Natsuki Kasuyal, Yuko Kusakal, Naoto Habu andAtsushi Ohnishi.Cellulose 9:263-269,2002.X M Chen, Y Q Liu, F Qinetal.J.Chromatogr.A, 2003,1010:185~19).
Therefore, be badly in need of a kind of flowing of developmental research and select wide adaptability and the high chiral stationary phase of fractionation ability mutually.
Summary of the invention
The objective of the invention is to prepare the wide and high chiral stationary phase of fractionation ability of a kind of mobile phase range of choice.In order to achieve the above object, the present invention adopts coating process behind the first bonding to prepare a kind of chiral stationary phase of bonding-affinity composite type.The technical scheme that adopts is characterized as: at first prepare polysaccharide derivates (I) and (II), then polysaccharide derivates (I) is chemically bonded on the chiral stationary phase matrix, obtain fixedly phase of bonding type, again polysaccharide derivates (II) affinity is coated to that bonding type is fixing to be gone up mutually, obtains bonding-affinity composite type polysaccharide chiral stationary phase.The chemical bonding of this method by the first step can overcome fixedly shortcoming such as immobilized insecure, the easy loss of phase polysaccharide derivates of coating-type, and second step overcame fixedly shortcoming such as phase polysaccharide derivates configuration malleable of bonding type again by the affinity coating; Concrete reactions steps is as follows:
(1) preparation polysaccharide derivates (I) and polysaccharide derivates (II)
Polysaccharide is scattered in the pyridine of no water treatment, adds the polysaccharide derivatization reagent, reaction finishes and adds precipitating reagent after the cooling and make the product precipitation, after filtration, the washing afterproduct to constant weight, promptly obtains polysaccharide derivates in vacuum drying.
Described polysaccharide is: cellulose or starch or cyclodextrin or shitosan or xylan or glucan or carboxymethyl cellulose; The polysaccharide derivatization reagent is: phenyl isocyanate or 3,5-dimethylphenyl isocyanate or 3,5-dichloride base phenyl isocyanic acid or to methyl-phenyl isocyanate or 3,5-dinitrobenzoyl chloride or chlorobenzoyl chloride or 3,5-dinitrobenzoyl chloride or anisoyl chloride; Making product precipitation agents useful for same is methyl alcohol or ethanol; Its hydroxyl substitution value of polysaccharide derivates (I) is: 5%-50%; Its hydroxyl substitution value of polysaccharide derivates (II) is 30-100%.
(2) polysaccharide derivates (I) is scattered among the solvent I, is bonded on the chiral stationary phase matrix of solvent II swelling, obtain fixedly phase (A) of bonding type
Described solvent I is: oxolane or acetone or pyridine; Chiral stationary phase matrix is: the hydrolysate of polyacrylic acid or polymethylacrylic acid or polyacrylate or the hydrolysate of polymethacrylates or polyacrylamide or carboxymethyl cellulose or carboxylic polystyrene; Chiral stationary phase matrix is used after reacting chloride with thionyl chloride; Solvent II is: carrene or oxolane or pyridine or N, dinethylformamide.
(3) polysaccharide derivates (II) is coated to bonding type fixedly on the phase (A), obtains bonding-affinity composite type polysaccharide chiral stationary phase (B).
Remarkable advantage of the present invention is: polysaccharide derivates (I) is bonded on the chiral stationary phase matrix, obtain fixedly phase of bonding type, again by affine coating process, polysaccharide derivates (II) is coated in bonded polysaccharide chiral stationary phase surface, obtains bonding-affinity composite type polysaccharide chiral stationary phase and the chirality enantiomer is separated and prepares to be applicable to liquid chromatography.Method by chemical bonding is fixed on polysaccharide derivatives on the chiral stationary phase matrix, can use oxolane, carrene, chloroform etc. as the phase additive that flows, and having enlarged flows uses scope, the problem of avoiding chiral selector to run off mutually.And the affinity coating process by behind the bonding has overcome the fixedly low shortcoming of phase chiral resolution ability of bonding type.
