Q:Why the silicon hydride less, a lot of hydrocarbons.
Silicon-based organic matter, oxidized to form silica, this thing is hard, very high melting point of atomic crystals, but the existence of solid on Earth
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 a derivative?
Derivative refers to a complex compound in the hydrogen atoms or atomic groups replaced by other atoms or atomic groups derived more complex products.
Q:What is the derivative of benzene?
The most important use of benzene is the preparation of ethylbenzene, followed by the preparation of cyclohexane and phenol. Benzene by substitution reaction, addition reaction, oxidation reaction generated a series of compounds can be used as the preparation of plastic, rubber, fiber, , Detergents, insecticides, etc. Approximately 10% of benzene is used as a raw material for the production of benzene-based intermediates, and benzene has good solubility as a solvent in chemical production.
Q:What is organic matter? Candle is organic?
Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
Q:What are the characteristics of the reduction of carboxylic acid and its derivatives?
NaBH4-ZrCl4 reagent system In the THF-toluene mixed solvent, at the reflux temperature, some of the carboxylic acid and its derivatives can be reduced to obtain the corresponding high yield of alcohol.
Q:How to identify carboxylic acid and anhydride
Acid chloride (anhydride) and alcohol;
Q:The difference between methanol fuel oil and alcoholized oil
Methanol is best burned
Q:What is cigarization?
Many people have a serious alcoholic misunderstanding that the longer the better alcoholization time, this is a beautiful misunderstanding, each cigar unique alcohol cycle is a lifelong pursuit of the mystery. For Cuban cigars, some support for 10 years after 8 years, you will be pleasantly surprised to find the cigar reached round mellow and, for example, Patagas, but some of the ten years will taste like chewing wax, cigars tend to death almost no taste.
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.
