Refrigerant gas is used in household , industrial and commercial airconditioning systems.
It can also be used as an aerosol propellant for pesticide and paint , or as a fire extinguishing agent.
It is a primary feedstock for fluoropolymers.
- Q: What is the isomeric structure of oxygen-containing derivatives?
- Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
- Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Nitrogen derivatives are; dimethylamine;
- Q: Compare the difference between London smoke and Los Angeles photochemical smog
- Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
- Q: Why does the molecular atom compound do not belong to the life structure
- Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
- 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 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: How to do it? Solve Inorganic Chemistry
- Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization
- Q: What is the difference between hot and cold asphalt?
- According to the time analysis, municipal companies should use the cold asphalt cold material, is the winter road maintenance of commonly used materials. In the long winter, the asphalt pavement works because of the temperature (less than 5 degrees is strictly prohibited construction), is very little construction, even if the construction, the quality is higher than the temperature when the construction is worse (asphalt mixture cold fast, easily lead to compaction The lack of pressure on the pressure, and prone to cohesive, poor water quality problems such as water), because no demand or demand is small, this time the major asphalt mixing field have a holiday home to the New Year. But the road will be the same as the winter disease, pit and other small diseases are not treated in time, easy to evolve into a large disease, there may be dangerous roadbed, running up the driver also curse, out of the accident maintenance department also bear responsibility, so the winter road Also need to maintain. At this time asphalt cold feed came into being, asphalt cold feed is used aggregate (graded gravel) plus dehydration asphalt plus diesel and additives mixed with the construction of the temperature requirements, the pits filled with pavement , Such as diesel fuel has finished bitter gluing together, but the construction quality is not good, no hot mix asphalt dense. So the winter is approaching, the road maintenance department will need to mix a few tons of asphalt cold feed sealed (to participate in 25kg rice), there are pits to pull a few bags to fill, and so on these problems when the pit and digging with the heat Mixed with asphalt material repair. In summary, the asphalt cold feed is a special winter pavement pit repair using the material, the construction process and hot mix asphalt material is roughly the same, but the construction quality is relatively poor, is a special time emergency measures, very useful materials.
- 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: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain
- Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.
- Q: How the most primitive life on earth is produced under what conditions
- The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
