Q:Storage of organic chemicals in the warehouse, ventilation requirements
Dangerous chemicals every time out of danger before the warehouse, dangerous warehouse should first open the fan, keep ventilated to avoid the concentration of flammable and explosive gases in the air is too high;
Q:Are all carbon compounds all organic?
No, carbon dioxide and carbonates, bicarbonate is not it
Q:Why is red coral red?
Red coral is not absorbed red, so it looks red.
Q:What is the position of Fischer-Tropsch synthetic hydrocarbons in Nazi Germany's military industry?
The traditional FT synthesis method of the product of heavy hydrocarbon content is high, the composition is complex, so the combustion efficiency is not optimistic. Germany is in view of the supply of oil is less than consumption (loss of production areas and lack of refined production capacity) was forced to take the FT technology to add (Germany's local coal reserves larger). So the FT fuel in the World War II Germany's energy system accounted for little, the specific data is still controversial, there are 15% and 25% said.
Q:Sodium can be used to identify derivatives of hydrocarbons
A compound in which a hydroxyl group is directly attached to a carbon atom in a hydrocarbon group or a benzene ring side chain is called an alcohol.
Q:The difference between methanol fuel oil and alcoholized oil
Change the smart car dual fuel control can be pure methanol and the whole solution
Q:Why is dry ice not organic?
Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.
Q:Derivatives of vinyl acetate
Vinyl acetate can produce reactions that occur most of the olefins or esters. Such as the addition of bromine to form dibromide, the addition of hydrogen halide to produce vinyl haloacetate, which is the only way to produce the substance because there is no corresponding halohydrin. The addition of acetic acid under palladium catalysis can produce ethylene diacetate and CH3CH (OAc) 2. The latter can undergo a transesterification reaction with many carboxylic acids. As an alkene, vinyl acetate can also undergo a Diels-Alder reaction and a 2 + 2 ring addition
Q:Is steel not organic synthetic material?
Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.
Q:What are the most stable carboxylic acid derivatives?
In addition to acid halide are more stable, which ester and amide stability is stronger
