Process for the preparation of dicyclopentylene [2,2'-bis(4-alkyl-6-t-butylphenols)] |
| abstract |
The invention concerns a process for the preparation of dicyclopentylene [2,2'-bis(4-alkyl-6-t-butylphenols)] of the formula I <IMAGE> (I) wherein R1 is tertiary butyl and R2 is methyl or ethyl, by the reaction of 1.5 to 2.5 moles of a 4-alkyl-6-t-butyl-phenol of the formula II <IMAGE> wherein R1 and R2 are as defined above, with 0.8 to 1.2 moles dicyclopentadiene at a temperature between 20 DEG and 120 DEG C. in the presence of an organic solvent and borontrifluoride or a complex thereof as catalyst, characterised by employment of specially selected solvents and reaction under practically anhydrous conditions. |
