Dehydrocoupling of toluene

Toluene dehydrocoupled products are produced by heating toluene in the vapor phase with an inorganic metal/oxygen composition which functions as an oxygen carrier and has the empirical formula: Ma1Mb2Mc3Ox where M1 is lead, M2 is bismuth, and M3 is at least one element selected from silver, zinc, in...

Beschreibung
Zusammenfassung:	Toluene dehydrocoupled products are produced by heating toluene in the vapor phase with an inorganic metal/oxygen composition which functions as an oxygen carrier and has the empirical formula: Ma1Mb2Mc3Ox where M1 is lead, M2 is bismuth, and M3 is at least one element selected from silver, zinc, indium, germanium, phosphorus, arsenic, thorium, the lanthanides or rare earths, Groups 1a, 2a, 3b, 4b, and 8 of the Periodic Table of the Elements, and mixtures thereof, and wherein a is 1, b is 0.01 to 10, c is 0.01 to 10, and x is a number taken to satisfy the average valences of M1, M2, and M3 in the oxidation states in which they exist in the composition. Alternatively, the same inorganic metal/oxygen composition can be employed as a catalyst or as a combination catalyst/oxygen carrier for the dehydrocoupling reaction when oxygen or an oxygen-containing gas is heated with the toluene.
