Effects of ammonia and amines on propylene disproportionation over a tungsten oxide silica catalyst
Journal Article

· J. Catal.; (United States)
Tungsten trioxide on silica catalysts, known to require a prolonged break-in period and to exhibit an anomalous gas-phase mass transfer effect for propylene disproportionation, was temporarily promoted by the injection of amines with N-H bonds, and inhibited by injection of pyridine and triethylamine. The increase of steady-state activity (428/sup 0/C, 3 g catalyst, containing 10% tungsten trioxide) was 283% with 0.1 cc n-butylamine, 233% with 0.1 cc hexylamine, 510% with 3 jl aniline, and 310% with 3 jl di-n-butylamine.
