Abstract: 1. A PROCESS FOR CONVERTING TOLUENE TO PHENOL, WHICH PROCESS COMPRISES: CONTINUOUSLY INTRODUCING A GASEOUS FEEDSTOCK CONSISTING ESSENTIALLY OF TOLUENE AND AN OXIDATION INITIATOR SELECTED FROM THE GROUP CONSISTING OF BENZALDEHYDE, BENZYL-ALOCHOL, AND MIXTURES THEREOF, TOGETHER WITH MOLECULAR OXYGEN IN SUCH AN AMOUNT THAT THE MOLAR RATIO OF OXYGEN TO BENZALDEHYDE IS ABOUT 1:1 TO 20:1 AND THE MOLAR RATIO OF ORGANIC COMPOUNDS TO OXYGEN IS ABOUT 1:1 TO 10:1, INTO A REACTION ZONE MAINTAINED AT SUPERATMOSPHERIC PRESSURE AND AT A TEMPERATURE OF FROM ABOUT 250*C. TO ABOUT 450*C; REACTING SAID FEEDSTOCK IN SAID REACTION ZONE, TO FORM A CRUDE REACTION MIXTURE COMPRISING BENZALDEHYDE, PHENOL, TOLUENE, AND BIBENZYL; CONTINOUSLY WITHDRAWING SAID CRUDE REACTION PRODUCT FROM SAID REACTION ZONE; COOLING SAID REACTION PRODUCT BELOW THE LIQUEFACTION TEMPERATURE OF THE ALDEHYDE AND PHENOLIC COMPONENTS THEREOF; RECOVERING PHENOL FROM SAID COOLED CRUDE REACTION PRODUCT; AND RECYCLING TO THE REACTION ZONE AT LEAST A FRACTION OF THE COMPONENTS OF SAID CRUDE REACTION PRODUCT INCLUDING AT LEAST A PORTION OF THE BENZALDEHYDE CONTAINED THEREIN.
