in some embodiments of the invention the products of reaction of ethane and carbon dioxide which comprise ethylene and carbon monoxide are contacted with an ethylene carbonylation catalyst along with an alcohol the ethylene and carbon monoxide stream may be passed into a different reactor for carbonylation or alternatively into another portion of the same reactor the alkyl propionate product can be converted to an alkyl acrylate in an oxidative dehydrogenation process unreacted ethane and carbon dioxide may be present in the product stream from reaction of ethane and carbon dioxide as well as in the product stream from carbonylation after separation of the carbonylation product stream ethane and carbon oxides may be recycled to the input of the reaction of ethane and carbon dioxide trace amounts of ethylene and alcohol may also be present unreacted ethylene and alcohol from the carbonylation reaction may be recycled to the input of the carbonylation reaction in some embodiments of the invention the alcohol is methanol the alkyl propionate is methyl propionate and the alkyl methacrylate is methyl methacrylate in these embodiments the method represents an integrated process for producing methyl methacrylate starting from ethane and carbon dioxide in some embodiments of the invention the ethylene and carbon.
