    摘要: A process is disclosed for the preparation of monoalkyl ethers of polyoxyalkyleneglycols having a boiling point greater than 290.degree. C and suitable for use as a hydraulic brake fluid, wherein a mixture of ethylene oxide and propylene oxide is reacted in an anhydrous alkaline medium, and at elevated temperatures and with a monoalkylether of diethylene glycol, in a preferred weight ratio oxides/glycol-ether comprised between 1.2 and 1.8. Preferably, the monoalkylether of diethylene glycol is the monomethylether which may contain a small amount of monoethylene glycol. The reaction product may be adjusted as regards viscosity by dilution with a minor amount of an alkoxy triglycol, e.g., butoxy triethyleneglycol.

    摘要: Textile treating compositions which are particularly adaptable for use on partially oriented textile yarn. These textile treating compositions contain a blend of organic esters which may also contain a wax, processing aids and blending agents. The blend of organic esters comprises a blend of alkylidyne trimethanol esters, and an effective amount of at least one member of the group of a diester of a dicarboxylic acid and an ethoxylated ester. The wax can be an ethoxylated fatty acid.
