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

Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?: Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.

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: The role of aromatic hydrocarbons: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", usually refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed-chain type. With the basic structure of the benzene ring, the history of the early discovery of such compounds have more aromatic flavor, so called these Hydrocarbons are aromatic hydrocarbons, and hydrocarbons that are later found to have no aromatic flavor are also commonly used in this way, such as benzene, naphthalene, etc. The homology of benzene is CnH2n-6 (n≥6).

Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?: From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.

Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic carbon can be used in various architectures (ring, chain, short or long chain, twisted or planar aromatic or heterocyclic or naphthenes containing N / S / X halogen / P, etc.) Reaction mechanism (electrophilic addition, nucleophilic substitution, carbon positive ion intermediates, etc.). Due to the large negative carbon power is not great, the number of hybrid tracks can be 2 to 4 and not too much. For silicon, because of the electronegativity is less than hydrogen, resulting in silane hydrogen bonds in the biased hydrogen to make it easy to break, so silane in the air can be spontaneous combustion (not to mention disilane and above) The formation of compounds (similar to the alkyl) between the basic and hydrogen is so unstable that other similar compounds are difficult to stabilize.

Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.

Q: How the most primitive life on earth is produced under what conditions: In the 4 billion years ago, the Earth's water environment, the atomic group into molecules, the formation of a new four-balance body, and the Earth in the formation process, has gathered a lot of interstellar organic molecules, these molecules combined into macromolecules, Of the gravitational field and the anti-gravitational field to find the appropriate combination of objects. Macromolecules, molecules and atoms are also dependent on the formation of the force field to find the appropriate combination of objects, the formation of a new complex four-force balance body, where the gravitational field to play a long-range attraction (5-20 atomic diameter), which It also limits the macromolecules to obtain the desired combination of objects on a large scale, so macromolecules are combined into a moving tissue form, the most primitive marine microorganism. The macromolecules that move can mainly use the method of orienting the electromagnetic force to gradually develop into the original tissue that can swim in the water, so they can obtain a large amount of food (four-force balance) and accumulate some molecules in the body , These molecules in the original microbial parent force field guidance, combined with the mother similar to the new micro-organisms, these primitive microorganisms is essentially a complex macromolecule formation of the four balance body, which is the prototype of biological gene replication.

Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.: 3. Organic matter is generally insoluble in water, soluble in organic solvents, low melting point. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects.
