Industrial Grade Stearic Acid For Rubber

Q:High school chemistry: Is the esterification reaction of carboxylic acid and alcohol a polymerization reaction?: No, the polymerization reaction is the reaction of the polymer, the esterification reaction is the reaction of the formation of small molecules

Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid: Are sp3 hybrid.

Q:Organic intermediates in the synthesis, what is the chemical choice: The reaction intermediate (or intermediate) is the intermediate product in the chemical reaction. Generally unstable, difficult to separate. It needs to be distinguished from the transition state: the reaction potential map in addition to the reactants and products, all the lowest points that reaction intermediates; transition state is the reaction curve of all the highest point, the specific query drug network, answer please you Adopt, thank you,

Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Is a hydrocarbon derivative.

Q:What are the nature of sugar: Carbohydrate compounds are the main source of energy required for all living organisms to sustain life activities. It is not only nutritious, but also some have special physiological activity. For example: liver heparin has anticoagulant effect; blood type of sugar and immune activity. In addition, the nucleic acid composition also contains carbohydrate-ribose and deoxyribose. Therefore, the carbohydrate compounds for medicine, has a more important significance.

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:What are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?: For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material

Q:China's largest asphalt production base where: Asphalt material is divided into asphalt and tar asphalt two categories. Asphalt is divided into natural asphalt and petroleum asphalt, natural asphalt is the oil exudation surface after long-term exposure and evaporation of the residue; oil asphalt is refined processing of residual oil residue, the appropriate process to deal with the product The Tar asphalt is coal, wood and other organic dry distillation processing of the tar after re-processing products. Most of the asphalt used in the project is petroleum asphalt, and petroleum asphalt is a mixture of complex hydrocarbons and their nonmetallic derivatives. Usually the asphalt flash point between 240 ℃ ~ 330 ℃, the ignition point than the flash point of about 3 ℃ ~ 6 ℃, so the construction temperature should be controlled below the flash point.

Q:The main role of sugar?: The energy of life

Q:Why is dry ice not organic?: Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.
