Reaktionsschritte

The alkylation reaction, example 11 from DE-A-1 271 682 was reworked analogously. In a 1 liter three-neck flask equipped with a thermometer, a magnetic stirring mechanism and a reflux condenser, 252.5 g (2.0 mole) nonene, 235.3 g (2.5 mole) phenol and 5.0 g catalyst from Example 2 and Example 3 were heated to 90° C. After 3 hours reaction time, the catalyst was filtered off. The filtrate was fractionated using a 10 cm Vigreaux column. In the boiling range from 159° C. to 181° C. the alkylation product nonyl phenol was obtained.
