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:What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.

Q:Calcium fatty acid is an organic or inorganic chemical: All fatty acids are organic chemicals

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 are insoluble in water and have a lower density than water

Q:The main role of sugar?: Carbohydrates as an important body of nutrients, mainly divided into four categories: monosaccharides, disaccharides, oligosaccharides and polysaccharides.

Q:The nature and use of cellulose derivatives: The basic rules of esterification and etherification of cellulose In the cellulose molecule, the position of the three hydroxyl groups in the glucose group is different, and the influence of the adjacent substituents and the spatial blocking effect are different. The relative acidity and dissociation of the three hydroxyl groups are: C> C> C When the etherification reaction is carried out in the alkaline medium, the C hydroxyl group first reacts, then the C hydroxyl group, and finally the C primary hydroxyl group. In the acidic medium for esterification reaction, the reaction of the hydroxyl reaction is difficult and etherification reaction in the opposite order. When reacted with a larger amount of substituted reagents, the spatial hindrance has an important effect, and the space hindering the smaller C hydroxyl groups is easier to react than C and C hydroxyl groups.

Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.

Q:Who knows which organic intermediates are good?: Tianjin Chi Sheng Trading Co., Ltd. is a professional engaged in domestic and international sales of chemical products business, after years of development, the company's business involves medicine, petrochemical, lubricants, coatings, dyes and other industries. With a complete technical support and staffing, product market is vast, sold all over the country. The company's main organic intermediates, pharmaceutical intermediates, chemical solvents and chemical additives four categories of hundreds of varieties.

Q:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: Should be able to ah and bromine water addition reaction and fade:

Q:The functional group of the derivative of the hydrocarbon: Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.
