Acrylonitrile is an intermediate used in the production of a number of polymers, including nylon (after conversion to hexamethylenediamine), acrylic fibers, and elastomers. It is used in the manufacture of many polymers including acrylonitrile butadiene styrene (ABS), a polymer used to make toys, pipes, musical instruments, and auto parts. The primary means of synthesizing acrylonitrile is ammoxidation of propylene: C_3 H_6 + NH_3 + 3/2O_2 rightarrow C_3H_3N + 3H_2 O The feed to a propylene ammoxidation process contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Taking 100 mol of feed as a basis, determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar amounts of all product gas constituents for a 30% conversion of the limiting reactant.
