The synthesis method of 1-ethyl-1H-benzimidazole has been known for a long time. There are many methods, let me tell them one by one.
First, it can be prepared by condensation reaction using o-phenylenediamine and propionic acid as raw materials. This reaction needs to be carried out at a suitable temperature and under the action of a catalyst. First, put the o-phenylenediamine and propionic acid in a certain proportion in the reactor, and add an appropriate amount of catalyst, such as p-toluenesulfonic acid. Warm up to a certain temperature, usually about 160-180 ° C. Keep this temperature and stir continuously to make the two fully react. After several hours of reaction, the reaction is completed, cooled, and then separated and purified, such as recrystallization, 1-ethyl-1H-benzimidazole can be obtained.
Second, o-nitroaniline and ethyl propionate are used as starting materials. First, o-nitroaniline is reduced to o-phenylenediamine. Commonly used reducing agents such as iron powder, zinc powder, etc. are reduced in an acidic environment. Then the obtained o-phenylenediamine is condensed with ethyl propionate under the action of an alkaline catalyst. Sodium ethanol and the like can be selected as the base, and heated to the reflux temperature in an ethanol solution for several hours. After the reaction is completed, a series of post-treatments, such as extraction, distillation, crystallization, etc., can be obtained. The target product.
Third, it can also be prepared by reacting 2-mercaptobenzimidazole with bromoethane. Dissolve 2-mercaptobenzimidazole in an appropriate solvent, such as N, N-dimethylformamide (DMF), add an appropriate amount of alkali, such as potassium carbonate, to bind the acid. Then slowly add bromoethane dropwise and react at a certain temperature, such as 60-80 ° C. After the reaction is completed, 1-ethyl-1H-benzimidazole can be obtained by filtration, washing, concentration, etc. < Br >
These are all common methods for synthesizing 1-ethyl-1H-benzimidazole, each with its own advantages and disadvantages, and the selection should be weighed according to actual needs.

For 1-ethyl-1H-benzimidazole, there are several precautions to be taken during storage and transportation.
This substance has certain chemical activity. When storing, it must be selected in a cool, dry and well-ventilated place. Because it may be sensitive to temperature and humidity, if it is in a high temperature and humid environment, it may cause deterioration and damage its chemical properties. The warehouse should be kept away from fire and heat sources, and must be stored in isolation from oxidants, acids, alkalis, etc., and must not be mixed with storage to prevent dangerous chemical reactions.
During transportation, extra attention should also be paid. The packaging must be tight to ensure that there is no risk of leakage. Transportation vehicles should be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. When driving, it is necessary to prevent exposure to the sun, rain and high temperature. The handling process needs to be light and light, and it is strictly forbidden to drop and heavy pressure to avoid packaging damage. Transportation should be carried according to the specified route, and do not stop in densely populated areas and busy cities for a long time.
Furthermore, when the operator comes into contact with this object, protective measures should be taken. Wear appropriate protective clothing, protective gloves and goggles, etc., to prevent it from coming into contact with the skin and eyes and causing injury. If it is accidentally touched, it should be properly handled according to the corresponding emergency rescue measures. All of this is to ensure the safety and stability of 1-ethyl-1H-benzimidazole during storage and transportation, and to prevent accidental changes.

It is difficult to determine the market price of 1-ethyl-1H-benzimidazole. When this substance is in the market, its price often changes due to many reasons.
Looking at the past, its price is like a leaf in the wind, fluctuating. At first, because its preparation method is not good, the materials used are difficult to find and the workmanship is complex, the price is high, and very people can easily ask about it.
Later, with the improvement of technology, the preparation method is more refined, the materials used are gradually easy to obtain, and the workmanship is slightly simpler, so its price will fall, and it will gradually be used more.
However, there are other reasons that affect its price. The supply and demand of the city is like a boat on water. If you need it, the price will rise, and if you supply more, the price will be depressed. If at a certain time many businesses are competing for this product, the demand will be greater than the supply, and the price will go high; on the contrary, if there are many producers and the demand is scarce, the supply will exceed the demand, and the price will decline.
Furthermore, the situation of the world and the regulations of the government will also have a great impact. If there is an obstruction in the business route, the material is difficult to pass, and the price may rise because of it; and if the government strictly regulates and the preparation is limited, it can also cause the price to change.
And its quality is different, and the price is also different. The price of the superior is high, and the price of the inferior is low, In order to know the current market price of 1-ethyl-1H-benzimidazole, it is necessary to carefully investigate the supply and demand of the city, changes in technology, regulations of government orders and quality conditions, etc., in order to obtain a more accurate number.
