Refrigerant gas is used in household , industrial and commercial airconditioning systems.

It can also be used as an aerosol propellant for pesticide and paint , or as a fire extinguishing agent.

It is a primary feedstock for fluoropolymers.

Q: What is carbohydrate? What is organic? What is it?: Organic matter and inorganic matter is to see if there is no carbon C

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: Is carbon monoxide an organic gas?: Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.

Q: What is organic matter?: Green plants use light to provide energy, in the chloroplast synthesis of starch and other organic matter, and the light energy into chemical energy stored in organic matter, this process is often said that photosynthesis.

Q: The functional group of the derivative of the hydrocarbon: Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.

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: Artemisinin is not a derivative of hydrocarbons: Artemisinin is a colorless needle-like crystal obtained from the compound inflorescences Artemisia annua L., which is (3R, 5aS, 6R, 8aS, 9R, 12S, 12aR ) - octahydro-3,6,9-trimethyl-3,12-oxo-12H-pyran [4,3-j] -1,2-benzodiazepine-10 (3H) -one. Molecular formula for the C15H22O5.

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: What cells are composed of compounds: The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.

Q: What is organic?: Organic products are from the organic agricultural production system, according to the international organic agricultural production requirements and the corresponding standard production and processing, and through third-party geographical and organic certification bodies certified all agricultural and sideline products, including food, vegetables, fruits, dairy products, animal products , Honey, aquatic products, spices, cosmetics, and even textiles, forest products, biological pesticides, organic fertilizers and so on. Is the organic cultivation of pesticides, fertilizers, contaminated raw soils, grows in the closest way to nature, and never uses synthetic compounds, fertilizers and transgenic technologies during the growth process. In the process of production In the absence of any synthetic chemical composition. From the processing, production, packaging the whole process is in line with environmental protection and health principles. International standards of organic certification required by the third-year certification bodies from the cultivation, processing, production, manufacturing, to the finished product wholesale process for review.
