Patent

CA 2321446

Improved methods for the simultaneous production of dihydroxybenzene and dicarbinol from diisopropylbenzene are provided. These methods provide for continuous and simultaneous production of DHP and HHP using Karr Column extractors operated in series. A very purity DHP-containing solution, the precursor to the dihydroxybenzene, can be produced according to the reported methods. A safe and efficient method for producing dicarbinol from HHP is also disclosed.

L'invention porte sur des procédés améliorés de production simultanée de dihydroxybenzène et de dicarbinol à partir de diisopropylbenzène. Lesdits procédés, qui recourent à cet effet à des extracteurs à colonne de Karr montée en série, permettent d'obtenir une solution très pure de DHP, le précurseur du dihydroxybenzène. L'invention porte également sur un procédé sur et efficace d'obtention du dicarbinol à partir de HHP.
