Versuchsvorschrift

The procedure of Example 1 was repeated except that 1.00 g (10.6 millimoles) of phenol, 11.4 g of the same C5 fraction as used in Example 1, and 1.00 g of Silica-Alumina "IS-28" (produced by Shokubai Kasei Kogyo Co., Ltd.) which had been burned at 500° C. for 10 hours were used. The acid strength of the silica alumina (as determined in the same manner as in Example 1) was as follows: H0 ≤- 8.2. The proportion of the unreacted phenol was 5.0%, and 0.05 g (2.9%) of o-tert-amylphenol, 0.22 g (12.6%) of p-tertamylphenol, 1.73 g (69.6%) of 2,4-di-tert-amylphenol, and 0.01 g (0.3%) of 2,4,6-tri-tert-amylphenol were formed.
