Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;

Q: China's largest asphalt production base where: Oil asphalt is the residue after distillation of crude oil. According to the degree of extraction of different, at room temperature into a liquid, semi-solid or solid. Oil asphalt color black and shiny, with a high temperature. Because it is in the production process has been distilled to 400 ℃ or more, and thus contain little volatile components, but there may still be high-molecular hydrocarbons without volatile, these substances are more or less harmful to human health.

Q: Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward: Pentane, g, x, n, decane, to eleven to hexadecane are liquid hydrocarbons. Ethanol is not a hydrocarbon, it is aerobic. Polymeric material is a compound of relatively high molecular weight Composition of the material, there are many, such as rubber, plastic, fiber, paint

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: Is acrylamide an oxygen-containing derivative of hydrocarbons?: There are many kinds of oxygen-containing derivatives of alcohols which can be classified into alcohols, phenols, aldehydes, carboxylic acids and esters, etc. The nature of the oxygen-containing derivatives of hydrocarbons is determined by the functional groups, and the nature of the organic compounds can be used to synthesize the oxygen- There is no organic matter to meet our needs.

Q: Sodium can be used to identify derivatives of hydrocarbons: A compound in which a hydroxyl group is directly attached to a carbon atom in a hydrocarbon group or a benzene ring side chain is called an alcohol.

Q: Is steel not organic synthetic material?: Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.

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: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok
