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 are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;
Q: What is the difference between an aromatic compound and a hydrocarbon derivative?
The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
Q: Identification of Derivatives of Chemical Hydrocarbons in High School
Give you a formula: halogen water consumption, alcohol sodium oxygen consumption, phenolic acid picking, aldehyde plus oxidation.
Q: Will AsH3 (arsenic trioxide) is organic or inorganic
AsH3 (arsine trihydride) is not containing C element
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: Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes
Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)
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: NH4HCO3 and so have C atoms ah, why still inorganic
Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.
Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
A little bit of a way to draw out with chemdraw, then convert structure to name
Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.
