Physical properties of contaminated trichloroethylene and 1,1,1- trichloroethane.

摘要

The specific gravity, volume change, dielectric constant, dissipation factor, boiling point, and nonvolatile residue carryover during distillation was measured for various contamination levels of rosin in trichloroethylene and 1,1,1-trichloroethane. Solvent stabilizers and the vapor pressure of solvents were examined. The effects of unknown contamination in solvents from manufacturing departments were measured. The theoretical effects of oil contamination on the boiling point are discussed. 18 refs., 15 figs., 13 tabs.
