What is the preparation method of (1-Methylethyl) -Benzenesulfonicacisodiumsalt Benzenesulfonicacid, (1-Methylethyl) -, Sodiumsalt?
The preparation method of (1-methethyl) -benzenesulfonic acid, that is, propylbenzenesulfonic acid, is as follows:
often starts with propylbenzene, so that the sulfuric acid or sulfuric acid can be reversed together. This is the process of sulfonation. In the case of propylbenzene, the propyl group is above the benzene, and the sulfonic acid group (-SO 🥰 H) in the sulfuric acid can replace the atom on the benzene. In contrast, the degree of reaction, the proportion of reaction and the proportion of reaction are controlled. If the degree of reaction is high, it will not cause side reaction, and the degree of reaction is not good; if the ratio is not high, it will also affect the rate of reaction.
Generally speaking, propylbenzene sulfonic acid can be obtained at the appropriate temperature, such as 40-80 ° C, and the temperature is low. In this case, the oxidized solution of propylbenzene sulfonic acid is used to neutralize the reaction. The reaction of the oxidized oxidizer in the propylbenzene sulfonic acid is generated into water, and the reaction of the sulfonic acid is the reaction of the oxidizer, so the propylbenzene sulfonic acid is obtained.
The process of neutralization, also pay attention to the reaction of the reaction, such as the acidity of the solution, to indicate the acidity of the solution or the pH, so that the reaction is just complete, in order to obtain the high degree of propylbenzene sulfonic acid. After the reverse is completed, the product can be obtained from the appropriate method, such as steaming, crystallizing, etc., and the product can be divided and extracted to obtain the product (1-methethyl) -benzenesulfonic acid.
