The single electron chemistry of coals. [Quarterly] report, January 1--March 31, 1993

Description: Following the position of the nitrile band and using the assumption that there is a linear relationship for between the extent of charge transfer and frequency, a 69% charge transfer was obtained and successfully replicates Flowers` results. If a Diels-Alder reaction occurred, we would expect the position of nitrile group to have shifted down field to the 2260-2240 cm{sup {minus}1} range for a saturated alkyl nitrile. There is no evidence for this type of reaction under these conditions since w… more

The single electron chemistry of coals. Quarterly report, October 1, 1993--December 31, 1993

Description: The objective of this work is to investigate and characterize the single electron reactions of alkyl and alkoxy aromatic compounds in order to determine the role these reactions play in the chemistry of coal. The work here is concerned with the interactions of coals, such as Illinois No. 6, with tetracyanoethylene.

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
