text: Even in this case, using solvents such as acetone, acetonitrile or tert-butanol, the selectivity to phenol rapidly dropped at very low benzene conversion, mainly due to the formation of dioxygenated products and tars: typically, selectivity was already less than 50% at benzene conversion as low as 5%.
