Abstract

PURPOSE: To obtain the titled compound with a good economic efficiency and operational rate, by washing a reaction gas of propylene with NH3, and O2 with an unsaturated (NH4)2SO4 solution, and separating oily substances from the resultant solution with the saturated (NH4)2SO4 solution in a crystallizing tank, and crystallizing and separating the aqueous layer in the crystallizing tank.
CONSTITUTION: Propylene is reacted with ammonia and oxygen or air, and a reaction gas 1 containing acryonitride, acetonitrile, hydrocyanic acid, ammonia and high-boiling polymeric compounds from a reactor is washed with an unsaturated ammonium sulfate solution containing sulfuric acid in a washing column 2, and then fed from the bottom through an outlet pipe 8 to an oil content separating tank 10 by a pump 9. A suturated ammonium sulfate solution from a crystallizing tank 14 is fed through a supply pipe 26' and mixed with the unsaturated ammonium sulfate solution in the tank 10 to separate oily substances 15. The solution after the removal of the oily substances 15 is fed from a supply pipe 17 to the crystallizing tank 14 to remove crystals 27 and used for washing the reaction gas 1 in the washing column 2.
EFFECT: Polymers and NH3 can be removed efficiently.
