R22 is primarily used as a refrigerant compound as well as in the production of polystyrene and polyurethane foam plastics.It is the most common refrigerant worldwide，however,it is going away
- Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination
- Hydrocarbons, halogenated hydrocarbons, esters are difficult to dissolve in water. Hydrocarbons, esters are denser than water, and the density of halogenated hydrocarbons is generally greater than that of water. Hydrocarbon derivatives containing hydroxyl, amino or aldehyde groups such as alcohols, phenols, aldehydes, carboxylic acids, sulfonic acids and amines are soluble in water, And the shorter the solubility of the carbon chain, the greater the solubility of the carbon chain increases, until the same number of carbon atoms and similar hydrocarbons.
- Q: Are the asphalt and peat kinds of vegetables have heavy metal?
- Asphalt and its flue gas on the skin and mucous membranes are irritating, phototoxic and carcinogenic effects. China's three major asphalt toxicity: coal tar pitch> shale asphalt> petroleum asphalt, the former two are carcinogenic. Asphalt main skin lesions are: phototoxic dermatitis, skin lesions limited to the face, neck and other exposed parts; black disease, skin lesions are often symmetrical distribution in the exposed parts, was flaky, brown - dark brown - brown black; Acne; verrucous vegetation and heat burns caused by accidents. In addition, there are dizziness, head swelling, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptoms and eye, nose, throat irritation symptoms.
- Q: Why is dry ice not organic?
- Dry ice is solid. It is a simple carbonaceous compound that is not the material basis for life. Therefore, dry ice is an inorganic compound
- Q: Are there two derivatives of equivalent hydrogen?
- You give the scope is too broad, at least to set in what kind of functional group range ah.
- Q: The role of aromatic hydrocarbons
- Aromatic compounds, historically, refer to a class of aromatic scent made from plant gums, but most of the currently known aromatic compounds contain no fragrance, so the word aromatic has been lost [1] The aromatic compounds are the general term for the carbocyclic compounds and their derivatives that conform to the Hockel rules, and their molecules have closed cyclic conjugated systems in their molecules; Π electrons meet 4n + 2, and the height is delimited; the bond length is averaged.Therefore, the compounds have a high degree of unsaturation, but the properties are relatively stable, such as easy to replace, and difficult to add and oxidation. This part focuses on the structure, naming, chemical properties, localization effects and application of aromatics in organic synthesis. [2]
- Q: Artemisinin is not a derivative of hydrocarbons
- There are many types of hydrocarbons, flammable and explosive materials, the structure of the known hydrocarbons in more than 2000. The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
- Q: What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?
- I think it 's harder if the thing is to be industrialized. = Such as carbon dioxide hydrogenation into methane, after the methane transport or storage is also a relatively large problem bars And not to say that the hydrogenation of carbon dioxide into methane has been studied for a long time, but it does not seem to have developed any big news like ah There is also electrochemical reduction of carbon dioxide. It is relatively easy to produce formic acid in the aqueous phase, such as the Partially oxidized atomic cobalt oxide for carbon dioxide electroreduction to liquid fuel (Nature: Nature Publishing Group) recently made by Xie Yi. The But the separation of formic acid and water is also a more difficult thing ah. The
- Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?
- Silicon compounds can also be made like this. However, for silicon-based organisms, the appropriate temperature of silicon-based enzymes is probably too high, the earth is too cold for them.
- Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- Organic matter is an abbreviation for organic compounds. At present, human beings know more than 900 million kinds of organic matter, the number is far more than inorganic.
- Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
- As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
