| synthesis | , it was produced by the method of adding chloride and then synthesizing the intermediate carvone. The process technology used by the factory, the foreign five-step reaction for the three-step reaction, the first addition of the silkworm product of the Ene, once again the reaction of 1 crude carvone. Technically, the problem of no nitrosyl chloride NOCL gas cylinder in China has been solved, and the removal of chloride, which has not yet been solved in the production at home and abroad, hydrolysis requires two-step reaction and the technical problems of low total yield (25% to 50% from abroad). The product is light yellow liquid, with the breath of spearmint, purity of ketone content of more than 95%, mainly used in the preparation of floral base, used in pharmaceutical synthesis, oral deodorant and other perfumed products.|
| Use | flavor. Mainly used for the preparation of spearmint flavor. levocarix, alias L-(-)-carvone, spearmint oil, 2, 3-dimethyl-5-isopropenyl-cyclohexanone -1, light yellow clear liquid, insoluble in water. Flavor additives used in foods such as chewing gum are the main raw materials of gummy candy and spices, and also used in medicines and toothpaste and other spices. It is used as cooling and cooling promoting agent, spearmint, caraway. It is also used in medicine, as a blended spice for mud application, cooling agent, flavoring spice and toothpaste, etc. used as chiral raw material |
| production method | isolated from spearmint oil by neutral sulfite method or hydrogen sulfide derivative method. Derived from the synthesis of d-arosylene. |
