Stearic Acid Powder

Q:Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: Halogen can be named after the alkane, the other can not

Q:What is the isomeric structure of oxygen-containing derivatives?: Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.

Q:Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.

Q:Commodity fine chemical industry is good or organic intermediates synthesis is better?: Domestic in terms of the day I think the high-end enterprises are not good into Such as Procter & Gamble Unilever, demanding, treatment Ye Hao, two intermediates is probably a little bit toxic, but do protective measures should be okay

Q:Is polyethylene a derivative of hydrocarbons?: No, the derivative of the hydrocarbon is an element other than c.H

Q:What are the sugar stocks?: COFCO Tunhe (600737): The company is mainly engaged in processing of tomatoes, involving sugar, fruit processing of agricultural and sideline products deep processing enterprises.

Q:What is "organic" and "inorganic" in chemistry?: Inorganic compounds are inorganic compounds, usually refers to non-carbon compounds. , Alkali, salt and so on.

Q:Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?: Research on the origin, preparation, structure, nature, change and application of elements, elements and inorganic compounds.For the comprehensive utilization of mineral resources, the production and research of inorganic raw materials and functional materials in modern technology are of great significance At present, inorganic chemistry is in the new period of vigorous development, and many edge areas are rapidly rising and the scope of research has been expanded. Inorganic synthesis, high - element chemistry, coordination chemistry, organometallic chemistry, inorganic solid chemistry, bio - inorganic chemistry and isotope Chemical and other fields.

Q:What are the inorganic compounds: Hydrocarbons and their derivatives.

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.
