Stearic Acid SA1825

Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).: Inorganic matter with carbon after, as if with their own ideas, began to build their own. So slowly evolved into a complex organic matter

Q: Why is dry ice not organic?: Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.

Q: Is the resin a dangerous chemical? Is there any other alias?: Liquid resin containing organic solvent is a dangerous chemical

Q: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: Hydrocarbon derivatives of hydrocarbons do not belong to non-methane total hydrocarbons

Q: Is steel not organic synthetic material?: Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.

Q: Comparison of Solubilization of Benzene and Its Derivatives: ) Benzene physical properties: benzene is a color, with a special smell of liquid, the density is smaller than water, insoluble in water, benzene boiling point is 80.1 ℃, the melting point is 5.5 ℃

Q: High school chemistry: Is the esterification reaction of carboxylic acid and alcohol a polymerization reaction?: No, the polymerization reaction is the reaction of the polymer, the esterification reaction is the reaction of the formation of small molecules

Q: Commodity fine chemical industry is good or organic intermediates synthesis is better?: Domestic in terms of the day I think the high-end enterprises are not good into Such as Procter & Gamble Unilever, demanding, treatment Ye Hao, two intermediates is probably a little bit toxic, but do protective measures should be okay

Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Should be a hydroxy compound.

Q: What are the sugars?: Carbohydrate carbohydrates, also known as carbohydrates, are the most widely distributed and most important organic compounds in the world. Glucose, sucrose, starch and cellulose are all carbohydrates. X0d carbohydrates are all organisms The main source of energy needed to sustain life activities is not only nutritious but also has special physiological activity, such as: heparin in the liver has anticoagulant effect; blood sugar in the blood type related to immune activity.In addition, the nucleic acid The carbohydrate compounds are more important for medicine, and the carbohydrate compounds are composed of three elements, C, H and O, And O is usually 2: 1, and the proportion of water molecules, which can be expressed by the general formula Cm (H2o) n.Therefore, these compounds have been called carbohydrates, but later found that some compounds according to their structure and (C6H12O5), deoxyribose (C5H10O4), etc .; and some compounds such as acetic acid (C2H4O2), lactic acid (C3H6O3), and other compounds, such as acetic acid (C2H4O2), lactic acid (C3H6O3) And its composition is consistent with the general formula Cm (H2o) n, but the structure and properties are completely different with the carbohydrate compounds, so the name of the carbohydrate is not exact, but for a long time, so far still in use. X0d from Chemical structures, carbohydrates are polyhydroxyaldehydes, polyhydroxy ketones, and their condensates. <X0d sugars can be divided into three categories according to the hydrolysis and hydrolysis products: x0d monosaccharides: polyhydroxyalides that can not be hydrolyzed Such as glucose, fructose, etc. x0d disaccharides: hydrolysis of sugar to produce two molecules of monosaccharides such as sucrose, maltose, etc. x0d polysaccharide: can be hydrolyzed to produce many molecules of sugar monosaccharides such as starch, glycogen, Cellulose, etc. x0d sugars often use their names according to their origin.
