DEVELOPMENT OF A FIRE-RESISTANT WATER-BASE HYDRAULIC FLUID

Alkoxylation studies of 2, 4-toluylene diamine, hydroxy diphenyl oxide, oxydianiline, 4, 4'-methylene bis 2 chloroaniline, Bis phenol A, and N, N'-diphenyl p-phenylene diamine with ethylene oxide and glycidol in different mole ratios were completed. As a result, compositions of those alkoxylation products which provide for the lowest possible viscosities of their aqueous solutions at 25F without detrimentally affecting other properties such as autogenous ignition temperature, pour point, flash and fire points were established. Studies on the formulation of six selected fluid base stocks were initiated. A fluid composed of alkoxylated hydroxy diphenyl oxide as base stock, Ucon 90,000 as viscosity index improver, and water met the specifications for viscosity, pour point, autogenous ignition temperature, flash and fire points.
