Q: What is the difference between an aromatic compound and a hydrocarbon derivative?: The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.

Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination: The amount of forgotten, just remember the carbon six rings

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: Identification of Derivatives of Chemical Hydrocarbons in High School: Meaning that the halogenated hydrocarbon can be hydrolyzed and eliminated; the alcohol reacts with sodium to produce oxidation and eliminate the reaction; the phenol has acidity, can replace the reaction and color reaction; aldehyde can be added reaction and oxidation reaction. Finally remember the acid and acid, and alcohol esterification reaction.

Q: What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?: Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.

Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

Q: Why not ah?: A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbon it

Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.: 2. Previously, the known organic matter is obtained from animals and plants and other organisms, so this kind of compound is called organic matter. To the 1820s, scientists have used inorganic synthesis of many organic compounds, such as urea, acetic acid, fat, etc., to break the organic matter can only be obtained from the organic concept. However, due to historical and customary reasons, people still use the name of organic matter.
