β¦ Synopsis
C Withers, Raouf 0 Loutfy assigned to Atlantic Richfield Company A novel method of activating carbon is provided comprising contacting the carbon with low temperature aluminum chloride acid melts comprising at least 50 mole percent aluminum chloride and less than 50 mole percent of at least one halide salt capable of exhibiting a liquid state at atmospheric conditions, e.g., sodium chloride. Carbon activated according to the present invention is useful as a reductant of the chlorination of aluminous materials to produce anhydrous aluminum chloride.

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.
