Under normal temperature and pressure, Heptafluoropropane(HFC227EA) is a kind of colorless gas, and is a compressed liquefied gas to be stored in culinders. Heptafluoropropane(HFC227EA) extinguishant is an ideral substitute of Halon 1301, and is clean, low poisonous, and has a good fire-protecting effect. It is mainly used in total-flood extinguishing system.

- Q:Artemisinin is not a derivative of hydrocarbons
- A hydrocarbon is an organic compound (called a hydrocarbon) composed of two elements, carbon and hydrogen, and a hydrocarbon. Can be simply divided into open chain hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons, all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water.
- Q:Cracked
- It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions
- Q:What is organic matter?
- Green plants use light to provide energy, in the chloroplast synthesis of starch and other organic matter, and the light energy into chemical energy stored in organic matter, this process is often said that photosynthesis.
- Q:China's largest asphalt production base where
- Oil asphalt is the residue after distillation of crude oil. According to the degree of extraction of different, at room temperature into a liquid, semi-solid or solid. Oil asphalt color black and shiny, with a high temperature. Because it is in the production process has been distilled to 400 ℃ or more, and thus contain little volatile components, but there may still be high-molecular hydrocarbons without volatile, these substances are more or less harmful to human health.
- Q:Peracetic acid is not
- A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
- Q:Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward
- (3) polyethylene (2) is not, is a hydrocarbon derivative, there are C, H, O elements (3) polyethylene material (polyethylene material non-stick pan) (4) oil and oil produced gasoline is liquid , The general organic polymer materials can be burned
- Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
- Organic matter
- Q:What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:What is the difference between organic matter and inorganic matter?
- Organic matter that organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
- Q:Are the asphalt and peat kinds of vegetables have heavy metal?
- Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.
