Abstract
A process for vapor phase ammoxidation of hydrocarbons which comprises reacting vapors of ammonia and said hydrocarbon in the presence of a molten salt eutectic mixture of V.sub.2 O.sub.5 and K.sub.2 O, said molten salt being atomized in the presence of said ammonia and hydrocarbon, and, optionally, said spent molten salt being regenerated by air oxidation and recycled for reuse. The invention also embodies an apparatus for the ammoxidation process which comprises a reactor vessel fitted with (a) input means for ammonia and hydrocarbon, (b) an atomizing apparatus within said reactor, (c) means for feeding the molten eutectic salt from an upper reservoir to said atomizing apparatus, (d) a lower reservoir for spent molten salt, and (e) a gas-lift to move said spent salt from said lower reservoir to said upper reservoir.
