The experiment was done to synthesize acrylonitrile from propane in a
75 ml. reactor. It was performed in two processes; there are two steps in the
first process and one step in the second process. In the first step of the first
type, propane was converted to propylene by using Pd/Activated carbon as a
o
catalyst with the optimum condition: temperature 420 C, initial pressure 1 atm.
and reaction time 30 minutes. In the second step, propylene was transformed

to acrylonitrile by using two types of catalysts, i.e., Cu/multicomponent bismuth
phosphate and Cu/Zeolite. So, in the second process which directly converts
propane to acrylonitrile. The experiment was operated with Cu/multicomponent
bismuth phosphate; it was found that the optimum conditions were temperature
o
400 C, pressure 1 atm. and reaction time 30 minutes. The acrylonitrile was formed
at about 31.27%. In case of Cu/Zeolite catalyst, it can produce acrylonitrile
at only 6.29% by weight. The reaction using Cu/multicomponent bismuth
phosphate can produce acrylonitrile five times higher than when using Cu/Zeolite.

Keywords: ammoxidation, propane, acrylonitrile, multicomponent catalyst
