β─紫罗兰酮的生产
Manufacture of β─ionones
【摘要】 研究假性紫罗兰酮在浓硫酸中环化制备β-紫罗兰酮的工艺条件。反应介质为脂肪烃或氯代脂肪烃和低级醇的混合物。β-紫罗兰酮的摩尔得率83%以上,产品中紫罗兰酮的总含量>98%,β-紫罗兰回含量>95%。
【Abstract】 This article deals with the technological conditions for the manufacture of β─ionones by cyclitation of pseudoionones with sulfnric acid,using the mixtures of hydro carbons or chlorinated hydrocarbons and lowe alcohols as the reaction medium.The yield of β─ionones is more than83%,the concentration of ionones in product is more than 98% and β─ionones more than 95%.
