| titleOfInvention | Improvement in a process for the preparation of tertiary butylphenols |
| abstract | A subject of the present invention is a process for preparing tert-butylphenols, in particular tert-butyl-4 phenols, from a phenol and from an alkyltertiobutylether. The improvement consists in separating, at least in two stages, the reaction stages of alkylation of phenol and of transalkylation / isomerization of the unwanted alkyltertiobutylphenols, making it possible to flexibilize the type or quality of the final product, and to adapt easily to market requirements, improving on the other hand the total yield and providing good industrial hygiene conditions. Tert-butylphenols are useful intermediates in the manufacture of phenolic resins or antioxidants for rubber and many plastics. |
