摘　　要：测定了人造麝香DDHI在不同质量分数的乙醇水溶液中的溶解度 ,并用重结晶的方法提纯DDHI,适宜的工艺条件为 :用质量分数为 80 %的乙醇水溶液作为溶剂 ,将液态DDHI溶于 6 0℃的溶剂中 ,缓慢冷却至 2 0℃进行重结晶 ,溶液的pH =7,乙醇水溶液与DDHI的质量比为 2 3～2 6 ,进行二至三次重结晶可得到质量分数大于 99 5The solubility of DDHI in aqueous ethanol solutions was measured over the temperature range of 10°C to 60°C. 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°C, recrystallization temperature of 20°C, 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%.
