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:
Elastohydrodynamic film thickness in rolling contact bearing lubrication and bearing fatigue life are improved by employing a fluid comprising one or more cyclohexyl compounds having two or more cyclohexyl rings, said rings being fused, concatenated or linked by one or more C1 to C16 alkylene, carboxy, or ether linkages, each of said compounds having from 10 to 70 carbon atoms.
摘要:
A penetrating oil composition comprising (a) lubricating oil, (b) gasoline, (c) a monohydric alcohol, and (d) polyglycols, glycerols, their ethers or mixtures thereof.
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.

摘要:
A composition for use as a heat transfer fluid, hydraulic fluid or lubricant comprises at least one diphenoxybenzene and at least one mono- or di-phenoxydiphenyl. The diphenoxybenzene may be the meta- or para-isomer or a mixture thereof alone or containing the orthoisomer. The mono- or di-phenoxydiphenyl may be 2-phenoxydiphenyl, 4-phenoxydiphenyl, 2,21-diphenoxydiphenyl or a mixture thereof. The composition preferably comprises 1 to 60 parts by weight of diphenoxybenzene and the balance to 100 parts of diphenoxydiphenyl and may also contain ortho- and/or meta-terphenyl in amount up to 40 parts per 100 parts of the other components. The compositions of the invention remain liquid and thermally stable between 0 DEG C. and 375 DEG C.ALSO:Diphenoxybenzenes and mono- and di-phenoxydiphenyls are prepared by reacting an alkali metal phenoxide with the corresponding di-chlorobenzenes or the mono- or di-chlorodiphenyls at 280-320 DEG C. in the presence of copper as catalyst.
