摘　　要：报道了用化学法从生产β-紫罗兰酮的精留副产物(馏份Ⅱ)中分离回收β紫罗兰酮的方法。考察了物料配比、温度、pH值等因素对β紫罗兰酮回收率和纯度的影响。在确定的反应条件下得到了的β紫罗兰酮粗品,经减压分馏可得到纯度ω(β-ionone)>97.0%的产品,分离回收率>90.0%,从而降低了生产成本。产品经紫外、红外、质谱鉴定,证明了方法的可靠性。A method for separation and recovery of β-ionone from the production of fraction by-products was reported here. The effect of mole ratio, reaction temperature and pH balue on the recovery and purity of β-ionone was investigated. The recovery of β-ionone was >90.0% and the product purity ω(β-ionone) >95. 0% under the optimum reaction conditions. The product was characterized by UVIR and MS. The results showed the reliability of this method.
