The method of preparing 2-cyanoquinoline has been explored by many scholars in the past. The first method is also the reaction of nucleophilic substitution based on quinoline. First take an appropriate amount of quinoline, place it in a reactor, and dissolve it with a suitable solvent, such as dimethyl sulfoxide or N, N-dimethylformamide. Such solvents can promote the reaction and have a good affinity with the reactants.

Next, add cyanide reagents, such as potassium cyanide or sodium cyanide, etc. However, both are quite toxic and need to be carefully protected when used. In the reaction system, catalysts, such as copper salts, are often used to increase the reaction rate and reduce the activation energy required for the reaction. During the reaction, the temperature and duration are controlled, and the temperature is usually in a moderate range, such as between 100 and 150 ° C, and the duration or several hours to one day and night varies, depending on the progress of the reaction.

There is also a method of using o-aminobenzaldehyde and malonitrile as raw materials. Put o-aminobenzaldehyde and malonitrile in a certain ratio into a reaction apparatus containing an appropriate solvent, which can be ethanol or methanol, which can make the raw materials uniformly dispersed and favorable for reaction contact. Add a little catalyst, such as piperidine, and react under heating and reflux. When heating, water bath or oil bath temperature control, so that the reaction temperature is stable between 60-80 ℃, after a few years, the reactant gradually into 2-cyanoquinoline. After the reaction, the conventional separation and purification techniques, such as extraction, distillation, recrystallization, etc., to obtain a pure 2-cyanoquinoline product. In this way, a good method for preparing 2-cyanoquinoline can be obtained.

2 - What is the market price of Cyanoquinoline?

In today's world, the business situation is complicated, and the market is easy to change. The price of 2 + -cyanoquinoline in the market is also difficult to determine due to various reasons.

First, the source of the material has a great impact. If its raw materials are easy to harvest and the origin is abundant, the price is flat; if the raw materials are rare, difficult to find, and there is a shortage in supply, the price will rise. And the distance of the origin is also related to the freight, which is a variable of the price.

Second, the complexity of the process depends on the cost. If the method of preparation is simple and the consumption of manpower and material resources is low, the price may be inexpensive; if the process is complicated, exquisite equipment is required, and many steps are required, and specialized management is required, the cost will increase greatly, and the price will also be high.

Third, the demand of the market will influence the market. If the demand for this product in the pharmaceutical, chemical and other industries is strong, the supply is in short supply, and the merchant pursues profit, and the price will increase; if the demand is light and the supply exceeds the demand, the merchant will sell the goods, or reduce the price in order to sell.

Fourth, the regulations of the government cannot be ignored. The increase or decrease of taxes by the government and the tightness of environmental protection regulations are all related to costs. The tax is strict, and the cost rises and the price rises; the tax is light, and the cost falls and the price or falls.

Therefore, in order to know the price of 2 + -cyanoquinoline in the city, it is necessary to carefully examine the raw materials, processes, supply and demand, decrees and other things, and comprehensively, to obtain its general outline. However, the price is also difficult to have a constant number, and often changes with the world.
