Versuchsvorschrift

In an autoclave 222 g of 2-hydroxytetraline, 2.5 g of aluminium grit and 0.2 g of mercury(II) chloride are heated at 180° C for 1 h. After cooling 85 g of isobutylene are added and the mixture is stirred at 100° C for 3 h. In order to eliminate the catalyst the reaction product is washed with diluted hydrochloric acid. A subsequent distillation yields 212 g of 1-t-butyl-2-hydroxytetraline. Boiling point (13 mm Hg): 171° C. Melting point: 104° C.
