Abstract

1456406 Preparation of 4 - (m,m<SP>1</SP> - ditertbutyl - p - hydroxyphenyl) - butan - 2 - one BASF AG 22 Feb 1974 [24 Feb 1973] 8115/74 Heading C2C A compound of formula in which each R may be identical or different represents hydrogen or an aliphatic radical, is obtained by treating 2,6-ditert-butylphenol with a compound of formula in which R has the meanings given above, in the presence of a strong acid (having pKa of from - 7 to + 2À16) at an elevated temperature. The reaction may be carried out at a temperature of from 30‹ to 160‹ C., optionally in the presence of an inert organic solvent.
