Влияние температуры на реакции химического органического синтеза
Organic synthesis is a common chemical phenomenon in chemistry. Temperature has an important influence on it during the whole synthesis process. As the temperature rises, the heat-absorbing reaction will speed up, resulting in a significant change in the equilibrium constant; once the temperature decreases, The exothermic reaction will be accelerated.
Endothermic and exothermic, as the main characteristics of organic synthesis reactions, need to be paid enough attention to by researchers in the process of organic synthesis research. When the temperature reaches about 100C, the content of organic compounds will decrease, but when the temperature is lower than 50C, the content of organic compounds will be higher. Therefore, temperature has a great influence on chemical equilibrium.
1. Initiate the reaction; 2. Control the reaction rate; 3. Control the degree of reaction; 4. Adjust the direction of the reaction; 5. Prevent the volatilization of reactants.
In some chemical synthesis reactions, once the temperature rises, the mechanism will become more free, it is difficult to grasp the process of the entire synthesis reaction, and finally the selectivity will be significantly reduced. In addition, temperature will also dissolve related substances in the chemical reaction process. Solubility is an important parameter in the chemical reaction process. Changes in temperature will cause changes in solubility during the synthesis reaction process, resulting in different phenomena in the entire synthesis reaction.
