Application

Tetrafluoroethane is a main alternative for CFCs propellant ,it is widely used in MDIs(Metered-dose inhalers),it also named pharm-aerosol,or used as anti-asthma aerosol to treat asthma,COPD(Chronic obstructive pulmonary disease),and respiratory infections;it also could be used in Nasal Aerosol and foam aerosol to treat irritable rhinitis;its another use is in mouth and local aerosol(to improve nerve sensitivity ,strength tooth dynamic and relieve pain ,etc)

Storage & Transportation

The product is packaged and transported in steel cylinder ,ISO-TANK(or tank cars ).it should to be kept in cool and dry place , away from heat sourse ,avoid sunlight and raining .Transportation should comply with Chinese railway and road transportation regulations concerning hazardous cargo

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

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: Are the asphalt and peat kinds of vegetables have heavy metal?: Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.

Q: China's largest asphalt production base where: Coal tar pitch is a byproduct of coking, that is, the black material that remains in the distillation kettle after distillation of the tar. It is only fine with the physical properties of refined tar, there is no obvious boundaries, the general division method is to specify the softening point at 26.7 ℃ (cubic method) for the following tar, 26.7 ℃ above the asphalt. Coal tar pitch mainly contains volatile anthracene, phenanthrene, pyrene and so on. These substances are toxic, because the content of these components are different, the nature of coal tar pitch is also different. The change of temperature has great influence on coal tar pitch, which is easy to brittle in winter and easy to soften in summer. Heating with a special smell; heated to 260 ℃ in 5 hours later, it contains anthracene, phenanthrene, pyrene and other ingredients will be volatile.

Q: Sodium can be used to identify derivatives of hydrocarbons: Sodium can identify hydrocarbon derivatives that are alcohol

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: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

Q: Is steel not organic synthetic material?: Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.

Q: Inorganic chemistry employment direction? Current research direction: Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.)

Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: 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.
