Production method of beta-ionone

The invention discloses a production method of beta-ionone, which is used for large-scale and continuous production of beta-ionone, is used for producing beta-ionone by filling a tubular reactor with a solid strong acid catalyst, and comprises the following steps: uniformly mixing pseudo-ionone and a solvent, pre-cooling and cooling; filling a tubular reactor with a solid strong acid catalyst, and pumping the material into the tubular reactor to complete cyclization reaction to obtain beta-ionone; according to the method, liquid acid is replaced with solid acid, the tubular reactor is filled with the solid acid, separation of the catalyst and a liquid phase system, application of the solid strong acid catalyst, equipment corrosion retarding and three-waste emission reduction are effectively achieved, reaction conditions are mild, and energy consumption is low. 本发明公开了一种β-紫罗兰酮的生产方法，用于β-紫罗兰酮的规模化、连续化生产，其利用固体强酸催化剂填充至管式反应器中生产β-紫罗兰酮，其步骤为：将假性紫罗兰酮和溶剂混合均匀，预冷降温，固体强酸催化剂填充至管式反应器中，物料泵入管式反应器完成环化反应，得到β-紫罗兰酮；该方法用固体酸替代液体酸，填充至管
