The traditional method of extracting active ingredients such as steam distillation, vacuum distillation, solvent extraction method, but the process is complicated, purity is not high, but also easy to residual toxic substances. The supercritical carbon dioxide extraction of cheap, non-toxic, safe, efficient and able to produce high value-added products. Supercritical CO? Extraction method can extract the active ingredient from a wide variety of plants, and these components are extracted by chemical methods in the past do not come out. In addition to use in the chemical industry, chemical industry, but also used in tobacco, spices, food and so on. Such as foods, can be used to remove coffee, tea caffeine industrial CO2 can be extracted allicin, germ oil, sea buckthorn oil, vegetable oil and medicine with opium, atropine, ginseng vegetarian astaxanthin (English called astaxanthin, Acronym ASTA) and Ginkgo biloba, Taxus in valuable ingredients. The following examples brief application of the technology of carbon dioxide at room temperature and pressure is a colorless and odorless gas. CO? Molecule has 16 valence electrons, the ground state is a linear molecule, is D∞h point group. CO? Molecules and oxygen bond length 116pm carbon dioxide business, ranging from carbon-oxygen double bonds (acetaldehyde in the C = O bond length of 124pm) and oxygen triple bond (CO molecule C≡O bond length is 112.8pm) between the carbon dioxide, which has been described with a certain degree of triple bond characteristics. Thus carbon dioxide gas, some people think that there might be from the big π key fields, namely carbon atom and an oxygen atom in addition to the two keys, but also to form two three-center four large π bond electrons ice in CO? Molecules in the food and pharmaceutical The application can be successfully removed the residue, colloidal substances and oil and fresh products unbaked mixture before baking oven. Effective cleaning oven, mixing equipment, conveyors, moldings, packaging equipment, hobs, hobs, container, roller, freezer wall, biscuit oven strips. Benefits of dry ice cleaning: exclude the use of hazardous chemicals, avoid exposure to harmful chemicals production equipment and produce a second garbage; fiction or get rid of salmonella, Listeria monocytogenes bacteria, a more thorough disinfection, clean; exclude waterjet cleaning of electronic equipment damage; minimal equipment decomposition; reduce downtime. Groups of carbon dioxide _ Feng (online consultation) _ carbon dioxide Limited by Qingdao Industry and Trade of HSBC Group. Qunli Qingdao Fung Ltd.
