Q:Is polyethylene a derivative of hydrocarbons?
The definition is yes
Q:What are the derivatives of hydrocarbons?
Including alcohols, acids, aldehydes, ethers, esters, halogenated hydrocarbons and the like
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:Hydrocarbon and hydrocarbon derivatives system information! The
hydrocarbon
Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?
Although the relative molecular mass of oil is large, but does not belong to the polymer compound, the polymer compound should refer to a chain with a base number n of the material. Nor is it a derivative of saturated hydrocarbons. The oil is a non-saturated tallow fatty acid glyceride, and the fat is a saturated glycerol ester of saturated higher fatty acids. The more the double bond, the lower the boiling point
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:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
An electrolyte is a compound capable of being conductive in an aqueous solution or in a molten state, such as an acid, a base and a salt. Those compounds that can not be electrically conductive in the above cases are non-electrolytes such as sucrose, alcohol and the like.
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.
Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
Q:How the most primitive life on earth is produced under what conditions
The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
