摘要:
There are disclosed functional fluid compositions containing a two component friction modifier additive composed of a thio-bis-alkanol succinate ester and a phosphate diester such as dioleyl phosphite. The compositions are especially useful as tractor fluids.
摘要:
Oil-soluble 4-alkyl mono or 5-alkyl bicyclic oxazolidines, e.g. 1-aza-3,7-dioxabicyclo[3.3.0] octanes which are the reaction products of an aldehyde and an amino propane monol or diol are additives which feature activity in functional fluids, e.g. mineral oil base automatic transmission fluids, as copper alloy corrosion inhibitors.
摘要:
The present invention provides substantially saturated, e.g., hydrogenated, phospholipid compounds, such as hydrogenated lecithin, which are useful as friction modifying agents for oleaginous compositions such as fuels, and lubricating oils, particularly automatic transmission fluids. The present invention also provides oleaginous compositions containing such phospholipid compounds, and processes for preparing the hydrogenated phospholipids, such as hydrogenated lecithin, and the compositions in which they are contained.
摘要:
There is disclosed an automatic transmission fluid containing an improved demulsifier additive being a combination of an acylated alkoxylated isopentylphenolic resin and a propoxylated-ethoxylated amylphenolic resin, the additive being effective at concentrations of 30 to 50 ppm.
摘要:
The present invention provides certain metal (e.g., Ca or Mg) ester salt derivatives capable of exhibiting friction modification, oxidation inhibition, and corrosion inhibition properties in power transmitting fluids such as automatic transmission fluids. These salts are derived from mono or diesters prepared by the reaction of an alkanol (e.g., thio-bis-ethanol) and a hydrocarbon substituted succinic acid or anhydride, such as octadecenyl succinic anhydride.
摘要:
There are disclosed improved additives for power shift transmission fluids being amine or ammonium salts of mercaptobenzothiazole dissolved in excess amine. The additives are useful as corrosion inhibitors, anti-oxidants and friction modifiers.
摘要:
The present invention provides a novel cyclic phosphate such as 1,3-dioxa-2-phospha-6-thia-cyclooctane-2-(dodecylthiodi(ethyleneoxy)-2-oxide, and its use as an anti-wear, anti-oxidant, and/or friction modifying agent for oleaginous compositions such as fuels, and lubricating oils particularly automatic transmission fluids. A new use of overbased metal phenates and/or sulfonates as friction stability promoters for conventional friction modifying agents is also provided.
摘要:
There are disclosed power shaft transmission fluids such as automatic transmission fluids containing a multifunctional anti-oxidant, anti-corrosion and friction modification additive being an oil soluble aliphatic succinate ester of alkoxylated mercaptan.
摘要:
Oil-soluble spiro-[cycloalkane-oxazolidines], e.g. spiro-[cyclopentane-1,2-(4'-ethyl-4'-methylol)-oxazolidines-1', 3'] which are the reaction products of a cycloalkanone and an amino-propane monool or diol are additives which feature activity in functional fluids, e.g. mineral oil base automatic transmission fluids, as copper corrosion inhibitors and as chelating agents.
摘要:
Mineral oil based power transmitting fluids, such as automatic transmission fluids, are disclosed which contain 0.05 to 2.0 weight percent of an ester of a thio-bis alkanol and a C.sub.12 -C.sub.50 hydrocarbon succinic acid or anhydride, the ester being a multifunctional additive providing the properties of friction modification, corrosion inhibition, anti-wear, oxidation inhibition and extreme pressure properties to the fluids.
