| Abstract: | The solubility of DDHI in aqueous ethanol solutions was measured over the temperature range of 10 ℃ to 60 ℃.Recrystallization was used to purify mixture of musk DDHI.It was shown that the appropriate operation conditions were 80% aqueous ethanol solutions as solvent,solution temperature of 60 ℃,recrystallization temperature of 20 ℃,pH=7 and mass ratios of ethanol solutions to crude DDHI of 2.3-2.6.Through crystallization,purity of the product was higher than 99.5%. |
