English in the troposphere, the word "Troposphere" the prefix dichloromethane, by Greek "Tropos" (meaning "spin" or "mixed") Implied from. Because of the troposphere is the layer of the atmosphere in the most turbulent, most jet will fly over the top of this layer (ie, the tropopause) to avoid affect flight safety airflow. Stars in the universe there troposphere, the solar energy is spread out in addition to internal radiation dichloromethane original, as well as convection. That reaches the bottom of the solar atmosphere 0.71 solar radii from the sun outwards, this interval is called the troposphere. This change in the nature of a large layer of gas, the use of methylene chloride is very unstable, and down to form a clear convective motion. This is the outermost layer of the sun's internal structure. Astaxanthin (astaxanthin) is a natural oil-soluble pigment has broad application prospects in food additives, aquaculture, cosmetics, health products and pharmaceutical industries [1-6]. Extraction of astaxanthin many suppliers dichloromethane, such as ethanol extraction, acetone extraction, methylene chloride, etc. However, these methods exist to extract residual organic solvents, harm to human health. Supercritical CO? Fluid extraction method is simple and no environmental pollution. (See Further reading) Six adopt? CO supercritical extraction technology resources available. CO resources at home and abroad using supercritical extraction technology can be used are:? Yew, astragalus, ginseng leaves, astaxanthin, marijuana, musk deer, Artemisia annua grass, leaves, fritillary grass, eucalyptus leaves, roses, camphor leaves, jasmine, pepper, star anise, laurel, ginger, garlic, pepper, orange naringin, hops, miscanthus, lemongrass, sage, rosemary, clove, nutmeg, sea buckthorn, wheat, corn, rice bran, fish, tobacco, tea, coal, oil and so on. Beijing, Shandong, Hunan, Guangxi, Zhejiang, Jiangsu, Hubei (Jingzhou natural astaxanthin Ltd.) and other places some research institutes, universities and pharmaceutical and food companies are actively researching supercritical extraction technology, and made a number of encouraging results. Guangzhou Institute of Chemistry, Chinese Academy of Sciences and the Southern flour Group joint design, manufacture, 200L large supercritical and industrial test equipment installed as "August" national technology investment projects, was organized by the State Science and Technology Acceptance January 24, 1996, officially put into operation.
