| abstract | 1396107 2,6-Diisopropyl phenol CIBAGEIGY AG 13 Oct 1972 [15 Oct 1971] 48006/71 Heading C2C A process for preparing 2,6-di-isopropyl phenol comprises treating a 2,5-di-isopropyl-4- alkyl phenol of the formula or a 2,6-di-isopropyl-4-alkyl phenol of the formula in which R<SP>1</SP> is hydrogen or alkyl, R<SP>2</SP> and R<SP>3</SP> are alkyl and R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> together contain from 2 to 11 carbon atoms, with a sulphonating agent so that a sulphonic acid group is substituted on the molecule at the 4-position and subsequently removing the sulphonic acid group from the molecule by treatment with water. 2,5- and 3,5 - di - isopropyl - 4 - hydroxybenzene sulphonic acids formed intermediately are stated to be novel compounds. Examples are furnished. |
