| Abstract: | Melt crystallization was used to purify mixture of musk DDHI.It was shown that the appropriate operation conditions were crystallizing time 2 h,cooling rate 4 ℃/h for crystallization,heating rate 6 ℃/h for sweating,and sweat time 30 min.After crystallization,purity of the product was higher than 99.2%,and the yield was 63.2%. |
