The invention discloses a method for preparing
musk ketone efficiently and mildly. The method comprises the following steps: crushing musk, sieving musk, soaking musk by using
ethanol, performing
reflux extraction by using
ethanol, and performing
reflux extraction by using water to obtain a filtrate; soaking a filter residue by using hot water, and performing hot-pressing
distillation extraction to obtain a hot-pressed extract; concentrating the hot-pressed extract and the filtrate, centrifuging, washing, and dissolving in
distilled water to obtain a dissolved solution; adjusting the pH of the dissolved solution, filtering by using a
ceramic membrane, circularly washing, adding pure water for dissolving, decolorizing, filtering, and performing
spray drying to obtain the
musk ketone. By the method, the purity of the
musk ketone can be increased, and reaches above 99%; the preparation process is simple, and easy to operate; a treatment condition is mild, so that the musk
ketone is not affected; the extracting effect is good, more than 99% of the musk
ketone in the musk can be extracted; the method has the advantages of high efficiency, rapidness, achievement of high purity, and the like.
