In the present paper the authors report preliminary results for two series of substrates respectively associated with methane and with carbon monoxide production. Methane formation was examined by pyrolysis of guaiacol, the prototypical guaiacyl moiety, along with anisole (control), and a number of substituted guaiacols, including 2,6 dimethoxyphenol, isoeugenol, and vanillin. Carbon monoxide release was investigated by pyrolyzing benzaldehyde, the prototypical moiety, along with related carbonyl compounds including acetophenone (control), cinnamaldehyde and vanillin, the latter two respectively intended to illustrate the effects of extended conjugation and guaiacyl substitution. Experimental data are presented and discussed in terms of reaction mechanisms derived from two hypotheses - (1) the primary evolution of gas during lignite pyrolysis occurs from lignin-related residues in coal, and (2) the molecular topology of lignoid structures favors elimination of gases by concerted pericyclic reactions.
