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:Why does toluene not belong to the derivatives of hydrocarbons?: Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt

Q:Simply talk about hydrocarbons: Hydrocarbon oil is a substitute for petrochemical diesel bio-liquid fuel, is a substitute for oil energy. It is a kind of liquid fuel produced by the lipid exchange reaction under the action of the catalyst, which is made of various kinds of lipid compounds (rapeseed oil, cottonseed oil and various vegetable oil waste) and methanol as raw materials. Burning, no black smoke, no smell, no harmful gas discharge. After testing the physical and chemical indicators have reached the national standard. Is a renewable energy source of biomass, the required wide range of raw materials, cheap.

Q:Is steel not organic synthetic material?: Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.

Q:Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: The most basic hydrogen prefix plus a sound next to tell you that the elements of the common element of the standard situation is the same kind of gas bromide tellurium metal next to the word next to the sound next to no matter how much the child knows that this law will be recited next to the next Periodic table down to know the elements of the material highlights a good note

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:Are all carbon compounds all organic?: Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~

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:Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: Silicon-based organic matter, oxidized to form silica, this thing is hard, very high melting point of atomic crystals, but the existence of solid on Earth

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:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?: Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
