PHENOL–ACETONE MARKET AND KEY PLAYERS ON THIS MARKET The rate of phenol production will remain at the same level (~5 rel. %/y) in the coming decade. Up to 2010, it is planned to build new facilities with a general total capacity of ~1.5 million t/year for phenol, a value that makes up ~20 % of the current capacity (7.5 million t/year).


The present invention provides in a particular embodiment an improvement in the process for producing phenol by the acid-catalyzed cleavage of cumene hydroperoxide (CHP). The reactant stream fed to the cleavage reactor also includes the contaminant by-product dimethyl benzyl alcohol (DMBA) formed during the direct oxidation of cumene to CHP.


The yield maximized at phenol concentration (ca. 50 mg/l) where μ was also maximum. The variation of cell mass yield with phenol concentration can be rationalized by a material balance on phenol consumption. Phenol was consumed mainly for assimilation into biomass and for energy for cell growth and maintenance, . (11) 1 Y = 1 Y C + 1 Y E
