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:Is polyethylene a derivative of hydrocarbons?
The definition is yes
Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
I think that can be said so.
Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?
High school stage seems to learn alcohol, phenol, aldehyde, carboxylic acid and esters and amino acids
Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong
Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.
Q:The role of aromatic hydrocarbons
Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
Benzene is a hydrocarbon that is also the simplest aromatics
Q:Simply talk about hydrocarbons
Hydrocarbon products in the daily production, life is widely used, the most representative of the commercial life of the HCR433b hydrocarbon refrigerant, and the most representative of the automotive HCR436a hydrocarbon refrigerant.
Q:Why not ah?
Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2
Q:What does organic mean?
Fertilizer point of view, mainly organic fertilizer. Human synthesis of the first organic matter --- urea, but also organic matter. Organic manure is mainly manure and stool, straw straw and so on.
Q:What can hydrocarbons crack to carbon and hydrogen at high temperatures?
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
