Abstract
The nascent steps in the pyrolysis of ethyl esters have been studied in a set of heated micro-reactors. We have examined the thermal decomposition of ethyl propionate, \ce{CH3CH2COOCH2CH3}, a model for biofuels. The micro-reactors are small (roughly 1\,mm ID x 3\,cm long) silicon carbide tubes; transit times through the reactors are about 100\,$\mu$sec. Temperatures in the micro-reactors can be as high as 1700\,K and pressures are typically 100\,Torr. The products of pyrolysis are identified by a combination of 118.2\,nm photoionization mass spectrometry and matrix isolation infrared absorption spectroscopy. We find there are two major pathways for ethyl propionate decomposition. These are: \ce{CH3CH2COOCH2CH3 -> CH3CH2COOH + CH2=CH2} and \ce{CH3CH2COOCH2CH3 -> CH3CH=C=O + CH3CH2OH}. The nascent pyrolysis products undergo further, extensive fragmentation in the reactor.
