ABSTRACT:
A method for producing a mixture of ethylene and carbon monoxide by contacting ethane and an oxygen source at a temperature of at least 500° C. to produce ethylene and carbon monoxide. A method for producing an alkyl propionate by steps of: (a) contacting ethane and an oxygen source at a temperature of at least 500° C. to produce ethylene; (b) contacting an alcohol, ethylene and carbon monoxide with an ethylene carbonylation catalyst to produce the alkyl propionate; and (c) separating the alkyl propionate from byproducts and starting materials. The method further comprises condensing the alkyl propionate with formaldehyde to produce an alkyl methacrylate.
