Abstract: A process for the recovery of unreacted ammonia from the effluent from a reaction zone used to produce acrylonitrile or methacrylonitrile comprising quenching the reactor effluent with an aqueous solution of ammonium phosphate in at least two stages, thereby capturing the ammonia component of the effluent. The captured ammonia may be recovered by heating the aqueous ammonium phosphate, which then may be recycled. Contaminants present in the aqueous ammonium phosphate may be removed, for example by solvent extraction or wet oxidation, prior to recycle.

Abstract: A process for the substantial reduction or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

Abstract: By the method the ammonium sulphate formed during the manufacture of acrylonitrile by direct ammoxidation (reaction between ammonia and oxygen) of propylene or propane, ammonia and ogygen-containing gas, such as air on catalyst fluidized bed fitted in respective reactor, is eliminated to a great extent or completely. In the reactor organic substance, or substances, respectively, are introduced which react with practically all the residual ammonia without this affecting the acrylonitrile yield. It is preferable that the organic substance should be methanol which is introduced in the reactor at temperatures bellow the points of its carbonization.

Abstract: MANUFACTURE OF UNSATURATED POLYESTERS This invention relates to a non-catalytic process for the manufacture of curable unsaturated polesters comprising reacting (I) maleic anhydride with a polyhydric alcohol which may be a dihydric alcohol or a combination of a dihydric alcohol and a polyhydric alcohol containing three or more hydroxyl groups, and (2) further reacting the intermediate ester so-formed with a dibasic acid anhydride and an oxirane compound.
