- Department of Chemistry, Panjab University, Chandigarh-14 Manuscript received 8 April 1972; revised 27 August 1972; accepted 23 April 1973 Interaction of carbon blacks with sulphur, carbon disulphide and hydrogen sulphide at elevated temperatures results in appreciable fixation of sulphur, the optimum temperature for maximum fixation being 600° in each case. There are strong indications that sulphur is fixed through chemical bonding and is not held as a polymer in the micropores. The results also indicate that the fixation involves addition of sulphur at the unsaturated sites as well as at certain active centres forming stable carbon-sulphur bonds, and substitution of phenolic and quinonic groups initially present on the surface yielding thiophenolic and thioquinonic structures.
