The plastic industry uses large amounts of phthalic anhydride C_(8)H_(4)O_(3) , made by the controlled C_(10) H_(8) + (9)/(2) O_(2) rarr C_(8) H_(4) O_(3) + 2 CO_(2) + (5)/(2) H_(2) O Since some of the naphthalene is oxidised to other products, 80% yield is obtained. What weight of phthalic anhydrid would be produced by the oxidation of 256 g of C_(10)H_(8) . [Mw "of" C_(10) H_(8) = 128, Mw "of" C_(8) H_(4) O_(3) = 148]
