✦ Synopsis


13C n.m.r. spectroscopy has been applied to investigate a number of coal tar and petroleum-derived carbon blackfeedstocks. Application of the J-modulated spin echo technique is especially rewarding, as this method renders the quaternary carbons directly detectable. Thus the quality of carbon black feedstocks can additionally be gauged on the basis of the contents of quaternary carbons, which is a direct indication of the carbon yield in the carbon black production process.

Solvent-refined lignite (SRL) and bituminous coals (SRC) are only partially soluble in good standard carbon-13 n.m.r. solvents. A survey of other possible solvents for SRLs and SRCs showed thatsymtriazine at 86°C solvated SR L as well as pyridine, but did not absorb in the regions of interest (5-60
