摘要:
According to the present invention, novel oil soluble compositions useful as dispersants are provided by reaction of a mono- or polycarboxylic acid acylating reactant with at least one heterocyclic polyol of the formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are the same or different and are selected from the group consisting of H, alkyl and --CH(OH)R.sup.5, wherein R.sup.5 is C.sub.1 to C.sub.10 alkyl, and wherein X and Y are the same or different and are H or C.sub.1 to C.sub.10 alkyl, with the proviso that at least one of R.sup.1, R.sub.2, R.sub.3 and R.sup.4 is the --CH(OH)R.sup.5 moiety.
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:
Oil compositions comprising a lubricating oil and an oil-soluble hydrocarbon polymeric viscosity index improver such as ethylene-propylene copolymers which contain an antihazing amount of an oil-soluble metal chelating compound having a nitrogen atom and a hydroxy group separated by 2 or 3 carbons and containing a total of 5 to 50 carbon atoms. The invention also relates to the process for preparing said compositions.
摘要:
An alkanol fuel, particularly ethanol, for internal combustion engines is modified by the addition of at least a corrosion-inhibiting amount of a metal passivating fuel additive whereby the corrosion-inhibition and if desired carburetor-detergency activities of said fuel is improved.

摘要:
The combination of an oil-soluble borated acylated nitrogen compound (e.g., borated polybutenylsuccinic anhydride reacted with polyamine) and solvent oil is usefully added to gasoline fuel for combustion in a spark ignition internal combustion engine exhibiting dieseling (also known as after-run or run-on) whereby said combustion results in alleviation of said dieseling.
摘要:
Sodium containing additives in gasoline reduce valve seat recession and give other improvements in automotive internal combustion engines operating on lead-free gasoline. Preferably, the sodium-containing additive is a sodium derivative of an organic compound, e.g., a salt of an organic acid, or a dispersion of a sodium salt of an inorganic acid, e.g., a sodium carbonate dispersion.
