Product Description:


1. stored in a cylinder
2. a kind of compressed liquefied gas
3. non-destructive to ozone layer in the atmosphere

Hexafluoropropane(HFC236fa)extinguishant stored in a cylinder is a kind of compressed liquefied gas, which is colorless, non-corrosive, non-conductive and non-destructive to ozone layer in the atmosphere. Hexafluoropropane (HFC236fa) extinguishant is an ideal substitute of Halon 1211, suitable to fill a protection, also suitable to the site having man of all flooding.

Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
Pro-butylbenzene ethane
Q:The aromatic hydrocarbon derivative refers to monocyclic or polycyclic
To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision
Q:Inorganic chemistry employment direction? Current research direction
Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!
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:What is organic?
Human beings have a long history of organic compounds. As early as the 17th century, humans could only obtain some organic compounds such as protein, fat, carbohydrate and dyes from animals and plants as food, food and clothing. 1828 German chemist Wilhelm (F Wohler) for the first time with inorganic acid ammonium nitrate synthesis of organic urea. After 1844, people have synthesized a large number of organic compounds such as methane, acetylene, acetic acid, oil and sugar, and since then humans have made organic chemistry into the synthetic era. The development of synthetic organic matter is clearly recognized: there is no clear boundary between organic matter and inorganic matter, but there are some differences in composition, structure and nature. Now people already know that organic compounds in the composition of most contain carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen and so on. Any organic compound, its molecular composition contains carbon, the vast majority also contains hydrogen. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, so many other organic compounds are derived, it is generally believed that hydrocarbons and their derivatives are known as organic compounds, referred to as organic compounds; The chemistry of compounds is called organic chemistry.
Q:Why not ah?
A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
Halide only fluoride in normal temperature and pressure may be gaseous;
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:What is the most primitive person on earth?
These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
Q:What is the reason why the battery's energy density is much lower than the hydrocarbon?
You find the block out of the lithium battery thrown into the fire try ........ look at how the energy density
