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: 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 does organic and inorganic mean?: Organic and inorganic machine myself ~ female and male

Q: Organic organic compounds are organic matter?: Organic polymer compounds are organic matter

Q: Why is dry ice not organic?: Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.

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: Is not organic matter must not hydrogen ah?: Organic matter that organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life. 【Features】 Most organic compounds mainly contain carbon and hydrogen elements, in addition often contain oxygen, nitrogen, sulfur, halogen, phosphorus and so on. Part of the organic matter from the plant sector, but the vast majority of oil, natural gas, coal as raw materials, through artificial synthesis method. Compared with inorganic substances, the number of organic matter, up to several million kinds. The carbon atoms of the organic compound have a very strong ability to bind to each other to form a carbon or carbocyclic ring. The number of carbon atoms can be 1,2, it can be thousands, tens of thousands, many organic polymer compounds can even have hundreds of thousands of carbon atoms. In addition, the isotopic phenomenon of organic compounds is very common, which is the cause of many organic compounds

Q: What is "organic" and "inorganic" in chemistry?: The definition of 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 hot and cold asphalt?: Cold mixed high-strength asphalt concrete, by adding asphalt in the thermosetting resin, coupled with the right amount of solvent to form a semi-flow asphalt binder, and the appropriate mix of aggregate from the asphalt concrete mixture. This asphalt concrete is a very high strength of 60 ℃, 30mm Marshall stability of 30000N, flow 20-30 (1 / 10mm), the stability of ordinary asphalt concrete is about 3 times, with good rutting resistance. Hot asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.

Q: Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on: hydrocarbon

Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
