Versuchsvorschrift
The procedure was carried out exactly as described in Example 9, except that the solution of 600 g of a 96% pure pseudoionone in 1,200 ml of methylene chloride, and the 1,000 ml of sulfuric acid, were introduced simultaneously into the reactor in the course of 5 minutes instead of 10 minutes. The distillation gave 490 g of a 98% pure β-ionone, corresponding to a yield of β-ionone of 83.4% of theory.
