For 2-acetyl-3,5 (6) -dimethylpyrazine, the method of preparation is as follows:
First take the appropriate starting material, such as dimethylpyrazine as the group, and add it by acetylation method. An acetylating agent, such as acetyl chloride or acetic anhydride, can be selected. If acetyl chloride is used, dimethylpyrazine is placed in a suitable reaction vessel, and an appropriate amount of catalyst is added, such as anhydrous aluminum trichloride. This catalyst can promote the progress of the reaction and increase its rate. The reaction environment needs to be kept anhydrous and oxygen-free to prevent side reactions. Acetyl chloride is slowly dripped, and the temperature between them needs to be controlled. Usually it can be started at a low temperature, such as 0-5 ° C, and then gradually warmed to room temperature to make the reaction complete.
If acetic anhydride is used as an acetylating agent, appropriate conditions are also required. Concentrated sulfuric acid or p-toluenesulfonic acid is often used as a catalyst. In the reaction system, dimethylpyrazine and acetic anhydride are added, and the reaction is heated and refluxed for several hours. After the reaction is completed, the separation and purification steps need to be carried out.
It can be washed with water first to remove soluble impurities, and then extracted with an organic solvent, such as dichloromethane or ether. After the extract is dried with anhydrous sodium sulfate, the desiccant is removed, and the pure 2-acetyl-3,5 (6) -dimethylpyrazine is obtained by vacuum distillation. This substance has a wide range of uses in the fragrance industry, and high yield and purity can be obtained by this method.
