What is the chemical synthesis method of 4,4 '- (1,1,1,3,3,3-hexafluoropropane-2,2-diyl) diphenyl-1,2-diamine
To prepare 4,4 '- (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) diphenol-1,2-diethyl ester, the method is as follows:
First, suitable starting materials need to be prepared. In this reaction, 4,4' - (1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) diphenol and 1,2-dibromoethane are the key starting materials. The purity of these two substances is very important to ensure that there are few impurities, so as not to disturb the reaction process.
times, take an appropriate amount of base. Potassium carbonate, sodium carbonate and other bases are commonly used. Bases are essential in the reaction and can assist in the deprotonation of phenolic hydroxyl groups, promoting their nucleophilic substitution reaction with 1,2-dibromoethane.
Place the starting material and the base in a suitable organic solvent in a certain proportion. Such as N, N-dimethylformamide (DMF), acetonitrile and other polar aprotic solvents. Such solvents are soluble in reactants and help the reaction occur uniformly.
Then, the reaction system is heated to a certain temperature. Usually, the reaction temperature is controlled between 60-100 ° C. Appropriate temperature can increase the reaction rate, but not too high to avoid side reactions.
During the reaction process, it can be monitored by thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC). When the raw material point disappears or reaches the expected reaction level, the reaction can be stopped.
After the reaction is completed, pour the reaction liquid into an appropriate amount of water and extract the product with an organic solvent. Dichloromethane, ethyl acetate, etc. are commonly used. After several extractions, the organic phase is collected.
The organic phase is dried with anhydrous sodium sulfate or magnesium sulfate to remove the moisture. After that, it is distilled under reduced pressure to obtain the crude product in addition to the organic solvent.
The crude product can be purified by column chromatography or recrystallization. Appropriate silica gel and eluent are selected by column chromatography, and suitable solvent is recrystallized. Through these two, high purity 4,4 '- (1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) diphenol-1,2-diethyl ester can be obtained.
What is the price range of 4,4 '- (1,1,1,3,3,3-hexafluoropropane-2,2-diyl) diphenyl-1,2-diamine in the market?
The price of 4,4 '- (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) diphenol-1,2-diformaldehyde in the market is difficult to determine. The price of this product often changes due to various reasons, such as the method of preparation, the price of materials used, the situation of supply and demand, and changes in the market.
If the method of preparation is precise and simple, and the price of materials used is flat, the price may be slightly lower. However, if the method is complex and the materials used are expensive, the price will increase. And the market demand is strong, and the supply is small, the price will also rise; if the demand is light and the supply is large, the price will fall.
At present, the details of it are not known, so it is difficult to determine the price. However, it can be deduced that in the ordinary market scene, this product may be difficult to make and the materials used are rare, so the price should not be cheap. If it is of high quality and pure, the price per gram may range from tens of gold to hundreds of gold. However, this is only an approximate estimate, and the actual price must be changed according to market conditions. If you want to know the exact price, you should carefully examine the market situation and the seller's request.
What are the precautions in the preparation of 4,4 '- (1,1,1,3,3,3-hexafluoropropane-2,2-diyl) diphenyl-1,2-diamine?
In the process of preparing 4,4 '- (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) diphenol-1,2-diacetonitrile, there are many points to be paid attention to.
Quality of the first raw material. All kinds of starting materials used must be carefully selected, and the impurity content must be strictly controlled. If the raw material is impure, impurities are in the reaction or cause frequent side reactions, and the purity and yield of the product are affected. For example, due to the fact that the raw material contains trace metal impurities, the reaction path is offset, and the product color is not good, the subsequent purification is extremely difficult.
Reaction conditions are also critical. Parameters such as temperature, pressure, and reaction time must be precisely controlled. If the reaction temperature is too high, it may cause the decomposition of the reactants and intensify side reactions; if the temperature is too low, the reaction rate will be slow, time-consuming and inefficient. Pressure control is equally important, and improper pressure may affect the reaction process and product structure. The reaction time also needs to strictly follow the established procedures. If the time is insufficient, the reaction will not be fully functional; if the time is too long, it may cause overreaction.
Furthermore, the choice of solvent should not be underestimated. The appropriate solvent has a profound impact on the solubility and reactivity of the reactants. Solvents that can dissolve the reactants well and do not react adversely with the reactants and products should be selected. The wrong solvent is selected, or the reaction cannot occur, or the product separation is difficult.
In addition, the monitoring of the reaction process is By means of high performance liquid chromatography, gas chromatography and other analytical methods, the reaction process and product generation can be grasped in real time. According to this, the reaction conditions are adjusted in a timely manner to ensure that the reaction advances in the expected direction.
Finally, the separation and purification of the product requires careful operation. Due to the complex reaction system, the product is often mixed with impurities such as unreacted raw materials and by-products. Appropriate separation and purification methods, such as crystallization, distillation, column chromatography, etc., are selected to obtain high-purity target products. Improper operation of the separation process may cause product loss and reduced yield.
