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 hydrocarbon thing
Hydrocarbon, which is composed of two elements, consists of carbon and hydrogen. It is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen and so on. It does not react with strong acid, strong base, strong oxidizer (Such as: potassium permanganate) reaction, such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform (chloroform) and tetrachloromethane (carbon tetrachloride) and other derivatives in the Hydrocarbon molecules in the carbon atoms connected to each other to form a carbon chain or carbon ring molecular skeleton, a certain number of hydrogen atoms attached to the carbon atoms, so that each carbon atom to maintain the price of the type of hydrocarbon is very much, the structure of known hydrocarbons More than 2,000 hydrocarbons are the parent of an organic compound. Other organic compounds can be seen as derivatives of one or more hydrogen atoms in the hydrocarbon molecule that are replaced by atoms or radicals of other elements. Word, is the use of "carbon" consonant with "hydrogen" vowel synthesis of a word, with "carbon" and "hydrogen" the composition of the internal structure of the word, the hydrocarbon is the parent of all organic compounds can be said that all Organic compounds are nothing but the result of replacing some of the atoms in the hydrocarbons with other atoms.
Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
Agree upstairs chemdraw method.
Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?
There are many kinds of oxygen-containing derivatives of alcohols which can be classified into alcohols, phenols, aldehydes, carboxylic acids and esters, etc. The nature of the oxygen-containing derivatives of hydrocarbons is determined by the functional groups, and the nature of the organic compounds can be used to synthesize the oxygen- There is no organic matter to meet our needs.
Q:What is the position of Fischer-Tropsch synthetic hydrocarbons in Nazi Germany's military industry?
The FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.
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:What is the difference between organic matter and inorganic matter?
Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.
Q:Why is red coral red?
The main components of the red coral bone or coral as the general calcium carbonate. But the red coral bones can be made into jewelry, mainly due to its large bone density, the crystalline form of calcium carbonate for the triangular calcite rather than other common hard coral orthorhombic aragonite. Different crystal forms, combined with the trace element composition ratio is mainly Mg / Ca ratio and Ba / Ca ratio, even the same kind of red coral color texture is also slightly changed. This difference is the red coral growth environment and seawater composition may be, therefore, red coral skeletal trace element ratio has become the growth environment, the most important proof of the collection.
Q:Why the silicon hydride less, a lot of hydrocarbons.
You know silane bar, SiH4, this thing will be spontaneous, very unstable
Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.
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
