Q:What are the characteristics of organic compounds?
Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
Q:What is the difference between hot and cold asphalt?
According to the time analysis, municipal companies should use the cold asphalt cold material, is the winter road maintenance of commonly used materials. In the long winter, the asphalt pavement works because of the temperature (less than 5 degrees is strictly prohibited construction), is very little construction, even if the construction, the quality is higher than the temperature when the construction is worse (asphalt mixture cold fast, easily lead to compaction The lack of pressure on the pressure, and prone to cohesive, poor water quality problems such as water), because no demand or demand is small, this time the major asphalt mixing field have a holiday home to the New Year. But the road will be the same as the winter disease, pit and other small diseases are not treated in time, easy to evolve into a large disease, there may be dangerous roadbed, running up the driver also curse, out of the accident maintenance department also bear responsibility, so the winter road Also need to maintain. At this time asphalt cold feed came into being, asphalt cold feed is used aggregate (graded gravel) plus dehydration asphalt plus diesel and additives mixed with the construction of the temperature requirements, the pits filled with pavement , Such as diesel fuel has finished bitter gluing together, but the construction quality is not good, no hot mix asphalt dense. So the winter is approaching, the road maintenance department will need to mix a few tons of asphalt cold feed sealed (to participate in 25kg rice), there are pits to pull a few bags to fill, and so on these problems when the pit and digging with the heat Mixed with asphalt material repair. In summary, the asphalt cold feed is a special winter pavement pit repair using the material, the construction process and hot mix asphalt material is roughly the same, but the construction quality is relatively poor, is a special time emergency measures, very useful materials.
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:Peracetic acid is not
A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
Q:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC
Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
Q:Why not ah?
A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
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:Is polyethylene a derivative of hydrocarbons?
No, the derivative of the hydrocarbon is an element other than c.H
Q:Artemisinin is not a derivative of hydrocarbons
There are many types of hydrocarbons, flammable and explosive materials, the structure of the known hydrocarbons in more than 2000. 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.
