Thermal Degradation Products of Solvents and Hydraulic Fluids Used in Mining

摘要

The Bureau of Mines sponsored an investigation of the thermal oxidative degradation characteristics of certain solvents and hydraulic fluids used in underground mining operations. The following halogenated solvents were studied in view of their usefulness and their flame retardant property: tetrachloroethylene, Cl2C = CCl2; 1, 1, 2-trichloroethane, ClH2CCHCl2; and trichloroethylene, Cl2C = CHCl. The hydraulic fluids studied were representative of five groups approved by the Mine Safety and Health Administration for underground operation, namely: glycol-water solutions, mineral oil-water emulsions, synthetics other than phosphate esters, synthetic phosphate esters, and mixtures of phosphate esters with mineral oils and other ingredients.
