Although there are many practical applications using the conductance of fused salts, such as the commercial preparation of aluminum, sodium, potassium, calcium, and magnesium, there is very little in the literature on such conductance. Because organic compounds as a class do not conduct as well as inorganic electrovalent compounds, even less attention has been paid to the conductance of organic compounds in the fused state, or to the phenomena which allows some organic compounds to conduct a current in the fused state and not in the solid or normal state. Since the author had started this investigation in under-graduate work and had made several generalizations, it seemed worthwhile to follow up with more specific experiments in order to substantiate or revise the earlier observations. This investigation centered about the ability of various organic compounds to extinguish an electric arc. There have been many theories and explanations of the mechanism of arc extinction and with each theory a new method. This thesis attempts to set forth the reasons why organic compounds will or will not extinguish an arc. Some helpful criterea to aid in the selection of suitable arc extinguishers will be given.
