A novel method for the measurement of coal swelling in organic solvents, based on the measurement of particle size distributions, is presented. The technique is unusual in that there is a self-diagnostic feature, whereby if any of the assumptions on which the method rests are not fulfilled by a part
Kinetics of Bz202-initiated polymerization of VAC in pyridine at 60 ยฐ were investigated. The polymerization was significantly retarded by pyridine. The monomer exponent decreased from 2.5 at a relatively low [Bz2Oz] (1.0 x 10 -2 M) to 2.0 at [Bz202] /> 4.0 x 10 -2 M. The observed kinetic features we
The swelling of a low-rank coal under the influence of various solvents is examined and results compared with those for a similar coal in briquetted form. Results are interpreted in terms of the effects of briquetting on pore structure.
## Aromaticities (f,) determined for several solvent-refined coals (SRC) by 13C n.m.r. in sym-triazine solution and by the Brown and Ladner 'H n.m.r. technique have been found to be the same within
