The single electron chemistry of coals. [Quarterly], April 1--June 30, 1992

Description: Depolymerization of coals at low temperatures may offer advantages over thermal bond cleavage. Because bond cleavage energies of radical cations are lower than the corresponding homolytic bond cleavage energies of the same bond, generation of radical cations in coal may make possible depolymerization at lower temperatures. We seek to investigate the above possibility using single molecules containing functional groups common in coals. Since the generation of a radical cation requires the remova… more

The single electron chemistry of coals. [Quarterly] report, October 1--December 31, 1992

Description: Radical cation generation in coal may make possible depolymerization at low temperature. This possibility was investigated using single molecules containing functional groups common in coals. Single- electron oxidations of 4,4{prime}-dimethoxybibenzyl (DMBB) by Fe(III) (1,10-phenanthroline){sub 3}(ClO{sub 4}){sub 3}, in refluxing CH{sub 3}CN, gave incomplete mass balances; an attempt was made to identify the additional products. Part of these products were deduced to be dimer, p-methoxybenzylat… more
