5-Acetyl-2-chloropyridine1-(6-Chloro-3-pyridinyl)-1-ethanone

The main use of butyl-2-chloro-butane- (6-chloro-3-butyl) -1-butene is as an important raw material for the manufacture of various chemical compounds.
First, it can be used as a raw material for the synthesis of rubber. Such as the manufacture of butyl rubber, butene is the ingredient of rubber. Butyl rubber has high density and aging resistance, and is used in many fields such as rubber and rubber products. Because of its good density, it can keep the rubber for a long time and improve the safety of transportation. In terms of rubber products, its anti-aging and toxic properties can ensure the safety of use.
Second, butylene can be used in the synthesis of methyl tert-butyl ether (MTBE). MTBE is a high-octane gasoline additive. Adding it to gasoline can effectively improve the anti-explosion performance of gasoline, so that gasoline can be burned more fully in the engine, with less knock and less knock, without increasing the power of the engine, and can also reduce the emission of tail pollutants, which is beneficial to environmental protection.
In addition, butylene is also an important starting material for the synthesis of methyl methacrylate. It can be used to synthesize and react to chemical compounds such as methyl methacrylate. Methacrylate is the raw material for the manufacture of glass (PMMA), which has the characteristics of high transparency and resistance. It is used in the construction of glass, optical devices and other fields.
Therefore, butene has a significant role in the chemical industry, and its uses are diverse. It is indispensable from synthetic rubber to gasoline addition, and then to the synthesis of gasoline. It promotes the development of all phases.

If you want to make acetylene, you can use various wonderful methods. First, calcium carbide is phased with water, calcium carbide is also calcium carbide. Take lumpy calcium carbide, put it in a special generator, and slowly fill it with water, then calcium carbide and water will react quickly. The chemical principle is: CaC 2 + 2H 2 O → C 2 H 2 ↑ + Ca (OH) 2. This reaction is rapid, and the injection of water should be slow in order to control its rate. And this reaction generates a lot of heat, and the generator must properly dissipate heat to prevent accidents.
Second, it is done by methane cracking. In a high temperature and isolated from air, methane (CH) can be cracked to produce acetylene and hydrogen. Its chemical equation is: 2CH~ → C _ 2O _ H _ 2O + 3H _ 2O. However, high temperature conditions are required, usually around 1500 ° C, which requires strict equipment materials and processes, and high energy consumption. It is rarely used in ordinary laboratories and is mostly suitable for large-scale industrial production.
Third, it is made of ethylene. First, ethylene is added to bromine to obtain 1,2-dibromoethane, and the reaction is: CH _ (2) = CH _ (2) + Br _ (2) → CH _ (2) BrCH _ (2) Br. Then, 1,2-dibromoethane is co-heated with a strong base (such as an alcohol solution of sodium hydroxide), and an elimination reaction occurs to obtain acetylene. The equation is: CH 2O BrCH 2O Br + 2NaOH (alcohol, delta) → C 2O H2O ↑ + 2NaBr + 2H2O O. This step is a little more complicated, but it is also a feasible method in specific situations.
All kinds of production methods have their own advantages and disadvantages. Calcium carbide reacts easily with water and is commonly used in laboratories; methane cracking is suitable for large-scale industrial use; ethylene conversion laws depend on raw materials and demand. It is necessary to choose the best one according to the actual situation.

Diborane has a special nature. Diborane is a colorless gas with a foul odor, so its smell is also. It is flammable and can spontaneously ignite, and it is easy to catch fire and burn in the air. If it encounters an open flame or a hot topic, it will cause intense combustion. This is the nature of combustion.
Diborane is highly toxic. If inhaled, it will cause great damage to health and damage respiratory, nervous and other systems. For example, as described in "Tiangong Kaiwu", the harm should be detailed to avoid its risk.
Its relative density is larger than that of air, about 2.14 times that of air, so it mostly accumulates in low places. The boiling point is -92.5 ° C, the melting point is -165.5 ° C. It is gaseous at room temperature and pressure. If the temperature drops slightly, it is easy to liquefy and solidify. This is the property of its gas-liquid-solid tri-state transformation.
Diborane reacts violently in contact with water, decomposing to produce boric acid and hydrogen, which is its property of interacting with water. And it can react with most metals and non-metals, showing active chemical activity. It is an important reagent in many chemical reactions. Due to its active nature, extra caution is required when storing and using to prevent accidental reactions.

What is the price of ethyl alum today? Because the price in the market often changes with supply, demand and the current situation, it is difficult to determine its fixed number. However, looking at the market conditions in the past, it may be possible to know the approximate.
I have heard that the price of alum is related to its quality, its place, and its time. The best ethyl alum is pure and free, and its price must be higher than that of the ordinary. If the place where it is produced is shipped from a long distance, the freight will increase, and the price will also increase. And it is different in time. If the value is urgently needed, the price will increase; if the supply exceeds the demand, the price may drop.
Remember the past, the price of ethyl alum in the market was between a few dollars and two silver per catty. When times are bad, wars are frequent, and materials are scarce, the price may rise; if there is peace, the flow of goods is smooth, and the price may be stable.
And the use of alum is indispensable in dyeing, weaving, metallurgy and other industries. The rise and fall of the industry also affects the price of alum. If the dyeing and weaving industry is prosperous, and there are many people seeking alum, the price will increase; on the contrary, if the industry is sluggish, the price may drop.
To sum up, the price of alum in the market is roughly between counting money and two silver per catty, but the actual price still depends on the current supply and demand, quality, and current situation.

For a gold deposit, the gold deposit is as follows:
The gold deposit is one column, facing one end, and the column has six columns, and then facing the base, there are three columns facing the base. From here, one step is the place where the gold is hidden.
In other words, the place where the gold is hidden, there is a pillar at the beginning, and one needs to face one end of this pillar. In this direction, six pillars can be built, and the foundation of these six pillars, and another three pillars face the base of the original pillar. Set here, and one step forward, that is, where the gold is hidden. In this way, if you hide gold pieces, you can help those who hide them in sequence and move according to their instructions, or you can get the gold hidden in B.
