Versuchsvorschrift

50 Parts of anisaldehyde, 100 parts of acetone and 15 parts of zinc oxide are heated for half an hour at 200° C and a pressure of 60 atmospheres. 46.2 parts of 4-(p-methoxyphenyl)-3-buten-2-one is obtained analogously to Example 9 in the form of yellowish crystals having a melting point of 74° C and a boiling point of 109° to 110° C at 0.1 mm. The yield is 90% of theory (based on anisaldehyde) at a conversion of 79% of theory.
