Stearic Acid 1801(1660)

Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: You know silane bar, SiH4, this thing will be spontaneous, very unstable

Q: Identification of Derivatives of Chemical Hydrocarbons in High School: Derivatives have gone, and give a specific range Well

Q: What is the difference between crude oil and asphalt?: Asphalt is the residue of crude oil

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: Is the plexiglass intermediate?: Acrylic acid and its ester polymerization of the polymer obtained collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, in which the most widely used polymethyl methacrylate. Poly methyl methacrylate abbreviation for the PMMA , Commonly known as plexiglass, is so far the most transparent synthetic material quality.

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.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.

Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: Benzene is a hydrocarbon that is also the simplest aromatics

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives

Q: Commodity fine chemical industry is good or organic intermediates synthesis is better?: Personal feeling Commodity fine chemical industry is good, such as cosmetics, daily chemicals, if it is high-end products, the profit is very high.

Q: Who knows which organic intermediates are good?: Tianjin Chi Sheng Trading Co., Ltd. is a professional engaged in domestic and international sales of chemical products business, after years of development, the company's business involves medicine, petrochemical, lubricants, coatings, dyes and other industries. With a complete technical support and staffing, product market is vast, sold all over the country. The company's main organic intermediates, pharmaceutical intermediates, chemical solvents and chemical additives four categories of hundreds of varieties.
