β¦ Synopsis
Charcoals were prepared in the laboratory under known carbonization conditions from hard and soft woods. The charcoals were studied by elemental analysis, adsorption of carbon dioxide at 195K, Hg porosimetry, DGA and ignition temperature measurements. The properties of the charcoals were compared and related to their performance in gunpowder. The charcoal giving evenly burning gunpowder had the highest internal pore volume. 120. Development of a non-destructive test for charcoal beds M. E. Smith and A. Bailey (Chemical Defence Establishment, Porton Down, Salisbury, Wilts, England).
Development of a non-destructive test for determining residual filter life is described; results for the dry air/dry charcoal system are given. Rate constants for various grain size charcoals, correlation between non-destructive and destructive testing and the relationship between non-destructive test penetration and loading on the charcoal are given.

Surface oxygen groups on carbon blacks were analyzed by several new techniques and some methods used previously were re-examined. Phenolic hydroxyl groups were converted to their acetate ester derivatives using radioactively labeled acetic anhydride in pyridine at 90Β°C. The drop in count rate on hyd
The potentiodynamic sweep technique was applied to detect surface oxides on carbon black (Vulcan XC-72) which was subjected to heat treatment, electrochemical and chemical oxidation and gas phase oxidation. The quinone-hydroquinone redox couple was observed in the potential range 50-1280 mV (vs n.h.
