Procedure
A mixture of 36.4 g of a 91% strength (corresponding to 0.19 mole) of 1,9-decadiene-3,8-diol and 74.5 g (0.61 mole) of methyl acetoacetate was heated to 200° C. in the course of 3 h. At about 160° C., elimination of methanol began, followed by elimination of CO2. A total of 14.1 g of low boilers (bp.<70° C.) distilled off, and 9.5 l of CO2 (theory 10.2 l) were eliminated. The residue (73.5 g) was then subjected to fractional distillation under greatly reduced pressure (oil pump).
