摘要
讨论了假紫罗兰酮酸化环合制备紫罗兰酮不同工艺条件对产品收率和组成的影响,结合有关文献重点探讨了作为维生素A工业合成原料的β-紫罗兰酮合成工艺条件的改进和优化,尤其是硫酸有机稀释剂(溶剂)的应用。
The effect of various technological conditions on the yield and composition of ionone, which was prepared from pseudo-ionone by acidification and cyclization, was studied. According to the references concerned, improvement and optimization of the technological conditions in synthesis of β-ionone which is a starting material in commercial synthesis of vitamin A, specially, application of sulfuric acid-organic dilue-nt(solvent), were emphasised.
