Reaction Steps
Into a 2 liter autoclave are charged citral (152 grams), methyl isobutyl ketone (500 grams) and zinc acetate dihydrate (38 grams). The reaction mixture is heated at 160° C. for a period of 12 hours. After filtering the catalyst the organic layer is washed with 10% salt solution. Distillation yielding 76 grams (32% yield) of the product, B.P. 126°-141° C./1 mmHg.
