Abstract

Ethylene oxidation on silver has been studied at 448 K and oxygen and ethylene (\(P_{C_2 H_4 } \)) partial pressures of 0.08 and 2×10−5−0.02 atm, respectively. The initial reaction orders with respect to ethylene in the selective and complete oxidation on silver surface purified by oxygen and hydrogen for\(P_{C_2 H_4 } \)=0.001–0.02 atm are close to 0.30–0.35 but upon decreasing\(P_{C_2 H_4 } \) to 2×10−5 atm, they diverge and become equal to 1.7 and 1, respectively.

Abstract

Исследовано окисление этилена на серебре при 448 К, парциальном давлении кислорода 0.08 атм и парциальных давлениях этилена (\(P_{C_2 H_4 } \)) 2×10−5−0.02 атм. Найдено, что начальные порядки по этилену процессов парциального и глубокого окисления на очищенной кислородом и водородом поверхности серебра в интервале\(P_{C_2 H_4 } \) 0.0001–0.02 атм близки к 0.30−0.35, но при снижении\(P_{C_2 H_4 } \) до 2×10−5 атм расходятся и становятся равними 1.7 и 1, состветственно.
