800 parts of mesityl oxide and 200 parts of geraniol have 1 part of oxalic acid added to them and the mixture is heated for three hours at a pressure of 50 atmospheres in the vibrated autoclave described in Example 1 at a temperature of 230°C. The reaction mixture is worked up by distillation. 141 parts of 4,8,12-trimethyl-3,7,11-tridecatrien-2-one is obtained with a boiling point of 92° to 94°C at 10-4 mm. The yield is 81% of theory at a conversion of 57% based on geraniol.
