Interaction between Sulfur Dioxide and Polar Molecules. I. Systems Containing Aliphatic Alcohols, Ethers, or Benzene in Carbon Tetrachloride

Abstract

The absorption band of sulfur dioxide near 2800 A in mixed solvents of benzene, aliphatic alcohols, or ethers with carbon tetrachloride is probably in part the result of a donor-acceptor complex with sulfur dioxide as acceptor. The characteristic constants for the MeOH, EtOH, n-PrOH, n-BuOH, and benzene complexes with sulfur dioxide, and the heats of formation of the benzene and ethanol complexes with sulfur dioxide in carbon tetrachloride have been estimated. The effect of atmospheric water vapor on these systems is also discussed.
