Versuchsvorschrift

A mixture of 30.0 g of 2-acetylamino-5-hexadecyloxyphenol, 20.0 g of Amberlyst 15 (produced by Rohm & Haas Co., U.S.A.) and 300 ml of toluene was stirred while heating at 80°-90° C., during which isobutene was bubbled therethrough for 5 hours. The reaction solution was filtered to remove solids and the filtrate was condensed. On adding 350 ml of n-hexane to the residue, crystals precipitated. The crystals were collected by filtration. 23.5 g of 2-acetylamino-4-tert-butyl-5-hexadecyloxyphenol was obtained.
