- Synthesis method of musk ambrette
-
The invention provides a synthesis method of musk ambrette. The synthesis method comprises the following steps of (1) mixing m-cresol, a phase transfer catalyst, a water solution of strong alkali and chloromethane, reacting and then generating m-methoxytoluene; and (2) mixing a catalyst and a solvent, dropwise adding the m-methoxytoluene for 0.5-2h, dropwise adding tert-butyl chloride for 0.5-2h, then reacting for 3-5h and generating tertiary butyl methoxyl methylbenzene. According to the synthesis method of the musk ambrette, methylanisole (replenishing sodium hydroxide to an aqueous alkaline solution, filtering out sodium chloride and then recycling) is synthesized by m-cresol and chloromethane in the water solution of strong alkali, so that compared with a traditional production technology, the yield is improved, treatment of waste water is reduced, manpower resource is saved, energy consumption is reduced and the synthesis method is safer and more reliable.

- Non-acid synthesis of nitro musks based on the ozone-mediated nitration using nitrogen dioxide
-
Three nitro musks, musk xylol 1, musk ketone 2 and musk ambrette 3, were prepared in good to moderate yield by direct polynitration of the respective aromatic materials with nitrogen dioxide in the presence of ozone.
