Abstract
2,6-Dialkylphenols are prepared by the interaction at below 90 DEG of a mixture (which is free of phenol and phenol generating ethers) of 2-R-C6H4OH (I) (where R is C2- 12 alkyl, C6- 12 cycloalkyl or C8- 12 aralkyl), an olefin and a catalytic quantity of the Al salt of I. Specified products are 2,6-di-tert-butylphenol, 2,6-di-(21-hexyl)phenol, 2 – (21 – hexyl) – 6 – (41 – octyl)-phenol, 2 – sec – butyl – 6 – ethylphenol, 2,6 – di-(dipropylcyclohexyl)phenol, 2 – tert – butyl – 6-(31 undecyl)phenol, 2,6 – di -tert – amylphenol, 2,6 – di(21 – heptyl)phenol, 2,6 – di (cyclohexyl)phenol and 2,6-di-(alpha-methyl-benzyl)phenol. A number of specific Al salts of I are also prescribed.
