What is BETA-CYCLODEXTRIN?

Cyclodextrin (CD), also known as Saltinger dextrin, is the second-generation supramolecular host compound, which is a chair-like conformation ring formed by D-glucopyranose linked by α-1,4 glycosidic bonds. Shaped oligosaccharides. Natural cyclodextrins include α-cyclodextrin, BETA-CYCLODEXTRIN and γ-cyclodextrin, which contain 6, 7, and 8 glucose monomers respectively, among which β-cyclodextrin is a cyclodextrin that can be commercialized on a large scale in industry. Dextrin products, its preparation method is simple, low cost, other commercially available β-cyclodextrin derivatives include carboxymethyl-β-cyclodextrin, glucosyl-β-cyclodextrin, ethylenediamine-β -cyclodextrin, hydroxyethyl-β-cyclodextrin, hydroxypropyl-β-cyclodextrin, sulfonate-β-cyclodextrin, quaternary ammonium-β-cyclodextrin and the like. Because of its rich hydroxyl structure, cyclodextrin has a good adsorption and wrapping effect on many organic molecules and inorganic heavy metals. It has the characteristics of safe raw materials, non-toxic, biodegradable, and good reusability. It is widely used in water treatment Research on the removal of organic and inorganic pollutants. According to the characteristics of water solubility and water insolubility, BETA-CYCLODEXTRIN and its derivatives can be used as flocculants, catalysts and adsorbents for water treatment, using the complexation, encapsulation, hydrogen bonding, electrostatic neutralization and catalytic degradation of target pollutants in aqueous solution systems function to achieve the purpose of removing the target pollutants.

BETA-CYCLODEXTRIN—Efficient Catalyst for Chemical Synthesis

1. BETA-CYCLODEXTRIN is the most efficient catalyst
The researchers first compared the catalytic effects of taurine, CTAB, TBAB, γ-cyclodextrin, and β-cyclodextrin catalysts, and found that β-cyclodextrin had the highest catalytic efficiency, while the same γ-cyclodextrin But dextrin has poor catalytic effect.

2. Select the most efficient concentration of BETA-CYCLODEXTRIN
Subsequently, the researchers compared the catalytic effects of 10mol, 20mol and 25mol of β-CD, and found that the catalytic effect was the best at the concentration of 20mol.

3. Find the most suitable reaction solvent and optimum reaction temperature
Next, the researchers compared the reaction effects in polar aprotic solvents (DMF, THF, and CH3CN) and polar protic solvents (H2O and EtOH), and found that in polar protic solvents H2O, EtOH:H2O (1 : 1) The medium reaction effect is the best.

In terms of reaction temperature, the reaction product yield is not high at room temperature, and when the temperature rises to 50 degrees Celsius, the reaction speed is the fastest and the reaction product yield is the highest.

4. Examining the Effect of Functional Groups
Meanwhile, the researchers tested the compatibility of various aromatic aldehydes with electron-withdrawing or electron-donating substituents with the reaction. The results show that the reaction can be carried out smoothly, and can tolerate a wide range of functional groups, such as chlorine, nitrobromide, fluorine, methyl, methoxyl, hydroxyl and phenyl, and the yield of products under the condition of electron-withdrawing substituents is relatively high. High, and slightly lower under the condition of electron-donating substituents, but both can obtain the corresponding products in good or excellent yields.

5. Examining Catalyst Reusability
Catalyst reuse can significantly reduce production steps and reduce production costs. At the end of the experiment, the researchers also studied the number of reuses of β-cyclodextrin. They found that BETA-CYCLODEXTRIN could be reused for 4 cycles, maintaining a high yield of 91%-84%. After 4 cycles, the reaction time increased and the product yield decreased.

Modification Method of BETA-CYCLODEXTRIN

BETA-CYCLODEXTRIN has relatively good solubility in water, and it is not easy to recycle when used in water phase, which greatly limits its application in water treatment. Cyclodextrin is a natural organic substance, safe, non-toxic and biodegradable. It is a better choice for cyclodextrin as adsorption, flocculation and photocatalytic materials. In order to improve solubility, dispersibility and long-term Stability, proper modification of β-cyclodextrin to make it have multifunctional, water-soluble or water-insoluble, high-dispersibility and other functional materials is very meaningful in water treatment. Usually, the methods of modifying cyclodextrin include chemical method and enzymatic method. Enzymatic method is mainly used to prepare branched cyclodextrin. Chemical method can use the outer alcoholic hydroxyl group of β-cyclodextrin to change its physical (solubility, mechanical strength, Size, specific surface area, etc.), chemical (chemical adsorption, complexation, electrical neutralization) and biological (antibacterial, degradable, etc.) properties, thus expanding its application in the field of water treatment. Chemically modified β-cyclodextrin can be classified into the following two categories:

1) Use the hydroxyl energy on the outer surface of BETA-CYCLODEXTRIN to react with multifunctional substances to generate various cyclodextrin derivatives with cyclodextrin as the skeleton to improve or reduce the concentration of β-cyclodextrin in water Solubility, it is mainly used as flocculant or coagulant in water treatment. It can play the role of moisture-proof, anti-oxidation and color protection in the food field. In the field of medicine, it can play the role of improving the solubilization of insoluble drugs. Analytical chemistry Domain can participate in the formation of stationary phase, play a role in molecular recognition and improve separation effect. β-cyclodextrin derivatives can be divided into cyclodextrin ethers, cyclodextrin esters, cyclodextrin-polymers and cross-linked cyclodextrins according to the chemical reaction of the introduction of new groups; The properties can be roughly divided into three types: hydrophilic, hydrophobic and ionic. Hydrophilic cyclodextrin derivatives include branched cyclodextrin, low molecular weight cyclodextrin polymer (molecular weight 3k ~ 6k), methyl cyclodextrin, hydroxyethyl cyclodextrin and hydroxypropyl cyclodextrin, etc. Hydrophobic cyclodextrin derivatives include ethyl cyclodextrin, acetyl cyclodextrin and polyacrylamide cyclodextrin, etc.; ionic cyclodextrin derivatives include quaternary ammonium or polyamine cyclodextrin, N- (2,3-Epoxypropyl)trimethylammonium chloride cyclodextrin, carboxymethyl cyclodextrin, alkylsulfonic acid cyclodextrin, phosphate ester cyclodextrin and sulfate ester cyclodextrin, etc.

2) Building BETA-CYCLODEXTRIN on other carriers can synthesize water treatment adsorbent materials with long service life, good mechanical properties or high dispersion properties. Carriers mainly include inorganic molecules, organic synthetic polymers and natural product polymers. Among them, inorganic carriers include graphene oxide, carbon nanotubes, SiO2 nanoparticles, magnetic Fe3O4 nanoparticles and zeolite, etc.; organic synthetic polymer carriers include polyethyleneimine, polyvinyl alcohol, polypropylene, polypropylene, polystyrene and Polymers such as polyester nanofibers; natural polymer carriers include cellulose and its derivatives, wood flour, chitosan, gelatin, sodium alginate, etc.
