A lubricant composition for improving fuel economy of a vehicle having an internal combustion engine includes a base oil and a friction-reducing compound. The friction reducing compound has the following general formula: wherein R is an alkyl or alkenyl group having 8 or more carbon atoms, each Ris an independently selected hydrocarbon group having 2 to 10 carbon atoms, and n is 1.

Friction-reducing compound, method of producing same, and lubricant composition

Disclosed are phosphinic acid compounds of formula I, II or III where Rand R' are for instance straight or branched C-Calkyl, Ris for instance straight or branched C-Calkyl, Rand R&#x2032; are for instance straight or branched C-Calkyl, Ris for instance straight or branched C-Calkylene and m is from 2 t 100. Also disclosed are polyester compositions comprising the compounds of formula I, II and III.

Solid state polymerization process for polyester with phosphinic acid compounds

Disclosed is a method for increasing the solid state polymerization (SSP) rates of metal catalyzed polyesters. The method comprises in a first step, reacting a dicarboxylic acid or a C-Cdicarboxylic diester with a diol at a suitable temperature and pressure to effect esterification or transesterification to prepare a precondensate and in a second step, reacting the precondensate to effect polycondensation at a suitable temperature and pressure to prepare a high molecular weight polyester and in a third step, further increasing the molecular weight and viscosity of the polyester under SSP conditions of a suitable temperature and pressure, where a metal catalyst is added in the first step or in the second step as a reaction catalyst, and where a certain phosphinic acid compound is added in the first step, in the second step or just prior to the third step. The polyester product exhibits low aldehyde formation during melt processing steps as well as excellent color.

Alkylamine, alkylenedi-, alkylenetri- or alkylenetetra-amine derivatives of N-alkyl-halo-acetamides, are useful as ashless, phosphorus-free and sulfur-free antiwear and friction modifying additives for lubricating oils. The additives are of the formula (I), (II) or (III) where A is alkylene of from 2 to 6 carbon atoms or is a group  G, each independently, is alkylene of 2 to 6 carbon atoms, R, each independently, is alkyl or alkenyl of 1 to 8 carbon atoms and R', each independently, is hydrogen or alkyl or alkenyl or 1 to 24 carbon atoms, where if an amide nitrogen is monosubstituted by alkyl or alkenyl, said alkyl or alkenyl is from 8 to 24 carbon atoms, where if an amide nitrogen is disubstituted by alkyl or alkenyl, the total carbon atoms of said alkyls or alkenyls combined are from 8 to 18 carbon atoms, and where each amide nitrogen is either mono- or disubstituted by alkyl or alkenyl.

Disclosed are borate and boronate compounds of the formulae where R, Rand Rare independently hydrogen, straight or branched chain alkyl of 1 to 24 carbon atoms, straight or branched chain alkenyl of 2 to 24 carbon atoms, cycloalkyl of 5 to 12 carbon atoms, aryl of 6 to 10 carbon atoms, aralkyl of 7 to 15 carbon atoms, alkaryl of 7 to 15 carbon atoms; Ar is substituted or unsubstituted aryl of 6 to 10 carbon atoms; and Rand Rare independently defined as for Rand may also be hydroxyphenyl or alkylated hydroxyphenyl, or Rand Rtogether with the &#x2014;OBO&#x2014; group form a substituted or unsubstituted 5 or 6 membered ring. The borate and boronate compounds are effective as antiwear, extreme pressure, and friction modifying additives for lubricating oils and fuels.
