What is the synthesis method of 3- (trifluoromethylthio) aniline?
The method of making triethylbenzyl musk requires delicate technology. First take the amount of raw materials, among which there is no benzene-based material. Dissolve it in an appropriate way, dissolve it, and seek to make the raw materials disperse without causing other reactions.
The liquid that dissolves the raw materials is placed in a specific reaction device. This device needs to be able to control and control, so as to ensure that the reaction is smooth. Pass into the catalyst, the amount of catalysis needs to be measured accurately, and the reaction speed is more, and it is easy to produce more; less reaction speed, and the reaction period.
Rise to a certain extent, this degree depends on the reaction characteristics and cannot be deviated. At this degree, the raw material molecules interact, and the reaction process is completed, resulting in the formation of triethylbenzyl-containing compounds. During the period, the reaction image of the material is observed, such as the color of the material, the generation of bubbles, etc., with the reaction degree.
When the material is formed in the middle, it is applied to separate the extraction. Or use the method of steaming, according to the boiling of the material, so that the material is divided into two parts. Or use the method of extraction to extract the specific material, and the material in the product is enriched.
The extracted material is then reversed in one step, and other required materials are added, and the reaction material is controlled again, so that it is in the direction of generating triethylbenzyl musk. After the reverse cleaning is completed, the fine lifting is carried out again to remove the raw material, and then the triacetylbenzyl musk can be obtained. The whole process requires a lot of operation, and each step is careful. If there is a slight difference, you can get a good product.
