“…X-Methylacetamide possesses certain properties which were considered advantageous for its utilization as a nonaqueous solvent-i.e., a high dielectric constant, 178.9 and 165.5 (3,4) at 30°and 40°C ., respectively, and a liquid range from 29°to 206°C. An organic solvent whose dielectric constant is of this magnitude offers the distinct possibility of serving as a solvent for many polarographically reducible substances, both inorganic and organic.…”
