Q:What is the hydrocarbon thing
Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
Q:What are the sugar stocks?
Gui sugar shares (000833): the company is based on sugar, paper-based, China's largest comprehensive production of sugar one of the enterprises.
Q:Calcium fatty acid is an organic or inorganic chemical
Fatty acid calcium is an organic chemical
Q:Carboxylic acid and carboxylic acid
The carboxylic acid can not react with the carboxylic acid, which is esterified with a hydroxyl alcohol, for example, acetic acid (acetic acid) reacts with ethanol (alcohol) to produce ethyl acetate with a special flavor.
Q:Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?
Heated to more than sixty degrees on the decomposition of things how to say that stability ...
Q:What is the difference between organic matter and inorganic matter?
Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.
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:What is cigarization?
The so-called eggplant, cigar egg alcohol cycle strict sense of each different cigars will have a slight difference, but generally still follow a certain law. There is an economic cycle concept in economics that can be applied to the alcoholic mature cycle of cigar applications. Each cigar has a certain maturity cycle, after the peak after the quality will decline with the taste and decline. The more cigars are, the greater the impact of alcoholic time on them. For example, for three months, the impact on fresh cigars can be huge, but for five years or more the impact of cigarettes is minimal.
Q:Are all carbon compounds all organic?
Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~
Q:The nature and use of cellulose derivatives
Starch can be used as a diluent, binder, disintegrant, and can be used to prepare dextrin and starch pulp. Chemical experiments with amylose test iodine. Of course, as a plant energy storage material can also eat. Organic derivatives such as rayon, cellophane and nitrates, acetate and the like, and ether derivatives such as methylcellulose, ethylcellulose, carboxymethylcellulose and polyanionic cellulose are prepared on the basis of textile and papermaking. Raw material is used as a dietary fiber.
