Caption: Catalysis. Molecular graphic of ethylene (CH2CH2) being oxidised over a silver catalyst (transparent grey). Coloured spheres represent different atoms: carbon = green (top); hydrogen = white; oxygen = red; chlorine = green (bottom). Molecular orbitals are shown in blue and yellow. In this reaction ethylene is oxidised to produce ethylene epoxide (CH2OCH2). Small amounts of chlorine are added to the silver catalyst to optimise the yield of epoxide versus complete combustion products.
