Toluene transformation on melted NaOH and KOH and the influence of bismuth, calcium, phosphorus, or vanadium oxide admixtures on the toluene conversion were studied in the temperature range 540-720 degreesC. The highest selectivity for dibenzyl was achieved on the NaOH-KOH (equiv) + 10 wt % V2O5 catalyst in air. The scheme of toluene transformation on melted NaOH is proposed.
