Q:Simply talk about hydrocarbons
Hydrocarbon oil is a substitute for petrochemical diesel bio-liquid fuel, is a substitute for oil energy. It is a kind of liquid fuel produced by the lipid exchange reaction under the action of the catalyst, which is made of various kinds of lipid compounds (rapeseed oil, cottonseed oil and various vegetable oil waste) and methanol as raw materials. Burning, no black smoke, no smell, no harmful gas discharge. After testing the physical and chemical indicators have reached the national standard. Is a renewable energy source of biomass, the required wide range of raw materials, cheap.
Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid
In the carbonyl R-COOH carbon, one of the O can only form a double bond with C, that is, a sigma bond and a Pi bond, and also with R and OH each form a sigma key, a total of four keys, C on the most The outer layer and no electrons to form solitary electrons. According to the principle of hybrid, because there are only three sigma, need to participate in the hybrid track can only be three, that is, sp2 hybrid.
Q:From the molecular level, are not all the energy obtained from the redox reaction?
You find the block out of the lithium battery thrown into the fire try ........ look at how the energy density
Q:The difference between methanol fuel oil and alcoholized oil
Methanol is best burned
Q:Will AsH3 (arsenic trioxide) is organic or inorganic
AsH3 (arsine trihydride) is not containing C element
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:Benzene derivatives are named from small groups to large groups or from large to small. The following three examples contradict each other ah!
The first should be called p-ethyl toluene, 2,3 pairs, should start from small groups.
Q:What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?
The FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.
Q:Does the carboxylic acid react with the Grignard reagent?
Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.
Q:What kind of carbohydrates?
Polysaccharides: starch, cellulose, agar, etc. Most food crops such as rice, wheat, corn, sorghum, potato, yam and so on are polysaccharides. Monosaccharides and disaccharides are not required in the body Digestive enzymes can be directly absorbed into the blood for the use of the body. Polysaccharides are required in the digestive enzyme under the action of decomposition into monosaccharides, disaccharides can be absorbed by the body after use.
