Procedure

Per hour, 2 parts of tri-n-butylamine are added to 1,000 parts of 3-methyl-3-buten-1-al and the mixture is passed for 2 minutes through a reaction tube at 220° C. and 12 bars. Distillation at 100 mm Hg gives 20 parts per hour of unconverted 3-methyl-3-buten-1-al and 970 parts per hour (99% of theory) of 3-methyl-2-buten-1-al of boiling point 77° C. This corresponds to a conversion of 98 percent.
