What is the Production Method of Chlorocinnamic Acid?

The preparation method of 2-chlorocinnamic acid has been known since ancient times. In the past, the production method was mostly based on the classical organic synthesis technique.
First, cinnamic acid was used as the starting material and prepared by halogenation reaction. Dissolve cinnamic acid in suitable organic solvents, such as dichloromethane and chloroform, because of its good solubility, the reaction can be homogenized. Then, in a low temperature and dark environment, slowly add halogenating reagents, such as thionyl chloride, phosphorus trichloride, etc. This is because the halogenation reaction is easily affected by temperature and light, and the control conditions are very important. After adding it dropwise, heat it up to a moderate temperature to make the reaction sufficient. During this period, it needs to be assisted by stirring to make the material mix evenly and accelerate the reaction process. After the reaction is completed, the impurities are removed by extraction, washing, drying, distillation and other steps to obtain pure 2-chlorocinnamic acid.
Second, benzaldehyde and chloroacetic acid are used as raw materials and prepared by Perkin reaction. First, benzaldehyde, chloroacetic acid and anhydrous potassium acetate are mixed in a reaction vessel in a certain proportion, and an appropriate amount of acetic anhydride is added. This reaction needs to be carried out under heating conditions, and the temperature should be controlled at 150-170 ° C. During the reaction, potassium acetate is used as a catalyst, and acetic anhydride participates in the reaction and provides acetyl groups. After the reaction is completed, the product is cooled, acidified, filtered, recrystallized, etc., to purify the product to obtain 2-chlorocinnamic
Third, styrene derivatives are used as raw materials to obtain halogenated styrene, and then obtained by carboxylation reaction. In the reaction system, a halogenating reagent is added to halogenate the styrene derivatives to produce halogenated styrene. Subsequently, under suitable catalyst and reaction conditions, carbon dioxide is introduced and carboxylation is carried out to finally obtain 2-chlorocinnamic acid. Although this method step is complicated, the reaction conditions can be flexibly adjusted according to the characteristics and needs of the raw materials to achieve the ideal yield and purity.

What is the price range of 2-Chlorocinnamic Acid in the market?

What is the price of 2-chloro cinnamic acid in the market? This question is quite crucial, and it is related to the trade-off of business affairs. However, there is no constant price in the market, and its price often changes for many reasons.
Let's talk about the supply first. If the supply is abundant and the supply exceeds the demand, the price will be cheap. The origin is abundant, the raw materials are abundant, and the workshop production is not worried, which can increase the supply, and the price may drop to tens of yuan per kilogram. On the contrary, if the supply is scarce, the supply is in short supply, and the price will be expensive. In the event of disasters in the origin, shortages of raw materials, or obstacles to transportation, the supply can be poor, and the price may reach hundreds of yuan per kilogram.
Let's talk about quality again. Those with high quality, the price will be high. With few impurities and excellent purity, it is suitable for high-end chemical and pharmaceutical research and development. Its price is not cheap, or more than 100 yuan per kilogram. And the quality is slightly inferior and contains more impurities. It is only used in ordinary industry, and the price is relatively low, or tens of yuan per kilogram.
Look at the market demand. If the demand is strong, the price will rise. For example, the demand for it in the pharmaceutical, spice and other industries has increased greatly. Many people ask for it, and the merchants will take advantage of the trend to raise the price, and the price may rise. If the demand is low, the merchant will reduce the stock or reduce the price to promote it.
Overall, the price of 2-chloro cinnamic acid in the market ranges from tens of yuan to hundreds of yuan per kilogram. Buyers should carefully inspect the supply, quality and demand in order to obtain a suitable price.
