Introduction:The cyclodextrin has a hole in the center of the ring structure. There is an oxygen atom bound by - CH - and glucoside inside, which is sulfur water-based. The - OH groups at positions 2, 3 and 6 of glucose are hydrophilic. Other molecules can be complexed to form inclusion complexes through weak van der Waals force. There are many substances that can be included by cyclodextrins, including rare gases, halogens, dyes, spices, drugs, food, pesticides and preservatives. After encapsulation, its stability, volatility, solubility and reactivity were improved. The special function of cyclodextrin makes it an inclusion material with wide application value. 1. Use in the pharmaceutical industry: cyclodextrin can form inclusion complexes (encapsulation) with drugs, which can stabilize (1) unstable drugs; (2) Deliquescence, adhesion or powdering of liquid drugs; (3) Insoluble or insoluble drugs can be dissolved (solubilized), etc. 2. Application in the pesticide industry: cyclodextrin inclusion stabilization, while some pesticides can be stored and improve the insecticidal efficacy. 3. Use in the food industry cyclodextrin is used in the food industry and has the following functions: (1) elimination and masking of special odor; (2) Improvement and improvement of food organization structure; (3) The reduction and removal of bitter taste; (4) Antioxidant effect; (5) Maintain and optimize flavor. 4. Use in daily chemical industry cyclodextrin can also be used as emulsifier and quality improver in cosmetics manufacturing. It also has deodorization (such as removing bad breath) and antiseptic effects, and can be used for the manufacture of toothpaste and tooth powder. 5. Other uses: it can be used as a treatment agent for oily sewage in environmental protection. The aqueous solution of cyclodextrin is used to clean the oil tank, and the waste liquid can be recycled to obtain fuel oil. 6. Use of cyclodextrin in the chemical field cyclodextrin is a valuable chemical reagent. When it is present, the fluorescence intensity of fluorescent pigment will increase significantly, so it can be used for the analysis of protein and amino acid; It can also be used to separate long-chain organic compounds and racemates. In addition, the adsorbent made of cyclodextrin can be used as adsorption for chromatographic analysis. This reaction can also be carried out in benzene (or acetonitrile). Although potassium cyanide is insoluble in benzene, if 18-crown-6 is added, not only the reaction can occur, but the yield can be as high as 95%. Toxicity of 18-crown-6: the oral lethal dose of rats is 300mg / kg. Irritating to eyes and skin.
