Ethylene (40vv) and oxygen (8vv) are used as stabilizers in nitrogen or methane gas (50vv) at 200~300℃ (the specific temperature depends on the model of the catalyst), silver catalytic conditions ethylene oxide is directly oxidized in a tubular fixed-bed reactor.
This is an oxidation exothermic reaction. 1 mole of ethylene and 0.5 mole of oxygen produce 1 mole of ethylene oxide.
The three largest patent suppliers in the world are SD (American Scientific Design Corporation), SHELL (Shell), and DOW (Dow Chemical).
