Q:What is organic matter? Candle is organic?
Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
Q:What is the position of Fischer-Tropsch synthetic hydrocarbons in Nazi Germany's military industry?
The FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.
Q:Hydrocarbon and hydrocarbon derivatives system information! The
hydrocarbon
Q:China's largest asphalt production base where
Coal tar pitch is a byproduct of coking, that is, the black material that remains in the distillation kettle after distillation of the tar. It is only fine with the physical properties of refined tar, there is no obvious boundaries, the general division method is to specify the softening point at 26.7 ℃ (cubic method) for the following tar, 26.7 ℃ above the asphalt. Coal tar pitch mainly contains volatile anthracene, phenanthrene, pyrene and so on. These substances are toxic, because the content of these components are different, the nature of coal tar pitch is also different. The change of temperature has great influence on coal tar pitch, which is easy to brittle in winter and easy to soften in summer. Heating with a special smell; heated to 260 ℃ in 5 hours later, it contains anthracene, phenanthrene, pyrene and other ingredients will be volatile.
Q:What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?
The principle is probably that the middle of the thing is the electrode, and then the surface of the electrode there are some powerful catalyst in the sunlight can promote the oxidation of water or carbon dioxide reduction. The electrode can move the proton to the other side and not allow the product or product to move to the other side. After the proton has been transferred, the electrochemical process can be used to hydrogenate the carbon dioxide.
Q:Is it possible to understand that organic matter is contained in the heat of inorganic matter?
Organic matter carries more richer and more easily utilized by creatures
Q:Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes
Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)
Q:Why is red coral red?
Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.
Q:What are the characteristics of organic compounds?
Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
Q:Are all carbon compounds all organic?
Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
