Definitions

  • N, N-dialkylaniline and substituted derivatives such as N,N-dialkylethoxyaniline can be prepared by reacting the appropriate aniline or substituted derivatives such as ethoxyaniline with aldehydes/ketones in a 1:2 or excess molar ratio in the presence of a reducing agent such as sodium triacetoxyborohydride in dichloromethane solvent.
  • a reducing agent such as sodium triacetoxyborohydride in dichloromethane solvent.
  • Lubricating oil compositions of the present invention may further contain one or more ashless dispersants, which effectively reduce formation of deposits upon use in gasoline and diesel engines, when added to lubricating oils.
  • Ashless dispersants useful in the compositions of the present invention comprises an oil soluble polymeric long chain backbone having functional groups capable of associating with particles to be dispersed.
  • such dispersants comprise amine, alcohol, amide or ester polar moieties attached to the polymer backbone, often via a bridging group.
  • Preferred groups of dispersant include polyamine-derivatized poly ⁇ -olefin, dispersants, particularly ethylene/butene alpha-olefin and polyisobutylene-based dispersants.
  • Particularly preferred are ashless dispersants derived from polyisobutylene substituted with succinic anhydride groups and reacted with polyethylene amines, e.g. polyethylene diamine, tetraethylene pentamine; or a polyoxyalkylene polyamine, e.g. polyoxypropylene diamine, trimethylolaminomethane; a hydroxy compound, e.g. pentaerythritol; and combinations thereof.
  • tetraethylene pentamine and (C) a polyhydric alcohol or polyhydroxy-substituted aliphatic primary amine, e.g. pentaerythritol or trismethylolaminomethane, as described in U.S. Patent No. 3,632,511 .
  • Mannich base condensation products Another class of ashless dispersants comprises Mannich base condensation products. Generally, these products are prepared by condensing about one mole of an alkyl-substituted mono- or polyhydroxy benzene with about 1 to 2.5 moles of carbonyl compound(s) (e.g., formaldehyde and paraformaldehyde) and about 0.5 to 2 moles of polyalkylene polyamine, as disclosed, for example, in U.S. Patent No. 3,442,808 .
  • carbonyl compound(s) e.g., formaldehyde and paraformaldehyde
  • Such Mannich base condensation products may include a polymer product of a metallocene catalyzed polymerization as a substituent on the benzene group, or may be reacted with a compound containing such a polymer substituted on a succinic anhydride in a manner similar to that described in U.S. Patent No. 3,442,808 .
  • Examples of functionalized and/or derivatized olefin polymers synthesized using metallocene catalyst systems are described in the publications identified supra .
  • the dispersant can be further post treated by a variety of conventional post treatments such as boration, as generally taught in U.S. Patent Nos. 3,087,936 and 3,254,025 .
  • Boration of the dispersant is readily accomplished by treating an acyl nitrogen-containing dispersant with a boron compound such as boron oxide, boron halide boron acids, and esters of boron acids, in an amount sufficient to provide from about 0.1 to about 20 atomic proportions of boron for each mole of acylated nitrogen composition.
  • Useful dispersants contain from about 0.05 to about 2.0 mass %, e.g., from about 0.05 to about 0.7 mass % boron.
  • the zinc dihydrocarbyl dithiophosphate can therefore comprise zinc dialkyl dithiophosphates.
  • the present invention may be particularly useful when used with lubricant compositions containing phosphorus levels of from about 0.02 to about 0.12 mass %, such as from about 0.03 to about 0.10 mass %, or from about 0.05 to about 0.08 mass %, based on the total mass of the composition.
  • lubricating oil compositions of the present invention contain zinc dialkyl dithiophosphate derived predominantly (e.g., over 50 mol. %, such as over 60 mol. %) from secondary alcohols.
  • Oxidation inhibitors or antioxidants reduce the tendency of mineral oils to deteriorate in service. Oxidative deterioration can be evidenced by sludge in the lubricant, varnish-like deposits on the metal surfaces, and by viscosity growth.
  • Oxidative deterioration can be evidenced by sludge in the lubricant, varnish-like deposits on the metal surfaces, and by viscosity growth.
  • Such oxidation inhibitors include hindered phenols, alkaline earth metal salts of alkylphenolthioesters having preferably C 5 to C 12 alkyl side chains, calcium nonylphenol sulfide, oil soluble phenates and sulfurized phenates, phosphosulfurized or sulfurized hydrocarbons, phosphorous esters, metal thiocarbamates, oil soluble copper compounds as described in U.S. Patent No. 4,867,890 , and molybdenum-containing compounds.
  • Friction modifiers and fuel economy agents that are compatible with the other ingredients of the final oil may also be included.
  • examples of such materials include glyceryl monoesters of higher fatty acids, for example, glyceryl mono-oleate; esters of long chain polycarboxylic acids with diols, for example, the butane diol ester of a dimerized unsaturated fatty acid; oxazoline compounds; and alkoxylated alkyl-substituted mono-amines, diamines and alkyl ether amines, for example, ethoxylated tallow amine and ethoxylated tallow ether amine.
  • Pour point depressants otherwise known as lube oil flow improvers (LOFI)
  • LOFI lube oil flow improvers
  • Such additives are well known. Typical of those additives that improve the low temperature fluidity of the fluid are C 8 to C 18 dialkyl fumarate/vinyl acetate copolymers, and polymethacrylates.
  • Foam control can be provided by an antifoamant of the polysiloxane type, for example, silicone oil or polydimethyl siloxane.
  • Fully formulated lubricating oil compositions of the present invention preferably have a TBN of at least 8.5, preferably at least 9, such as from about 8.5 to about 13, preferably from about 9 to about 13, and more preferably from about 9 to about 11 mg KOH/g (ASTM D-2896 and/or ASTM D-4739).
  • fully formulated lubricating oil compositions of the present invention derive at least 5 %, preferably at least 10 %, more preferably at least 20 % of the compositional TBN from ashless TBN sources including at least one compound of formula (I). More preferably, fully formulated lubricating oil compositions of the present invention derive at least 5 %, preferably at least 10 %, more preferably at least 20 % of the compositional TBN from at least one compound of formula (I), and less than 25 %, preferably less than 20 %, more preferably less than 15 % of the compositional TBN from ashless TBN sources other than compounds of formula (I), including basic dispersants.
  • weight (and mass) percents expressed herein are based on active ingredient (A.I.) content of the additive, and/or additive-package, exclusive of any associated diluent.
  • active ingredient (A.I.) content of the additive, and/or additive-package exclusive of any associated diluent.
  • detergents are conventionally formed in diluent oil, which is not removed from the product, and the TBN of a detergent is conventionally provided for the active detergent in the associated diluent oil. Therefore, weight (and mass) percents, when referring to detergents are (unless otherwise indicated) total weight (or mass) percent of active ingredient and associated diluent oil.
  • a fully formulated lubricating oil composition containing dispersant, a detergent mixture, antioxidant, ZDDP antiwear agent, pour point depressant and viscosity modifier, in base oil was prepared.
  • This lubricating oil composition which was representative of a commercial crankcase lubricant, was used as a reference lubricant.
  • Fully formulated lubricating oil compositions containing 1.68 mass% of the compounds of Synthesis Example 1 (Oil A) and Synthesis Example 2 (Oil B) were prepared. Also tested were fully formulated lubricating oil compositions containing 1.00 mass % (Oil C) and 2.00 mass % (Oil D) of the comparative compound of Synthesis Example 3.
  • An additional amount of base oil was added to each of the samples to provide comparable total mass.
  • the compounds of the invention as used in Oil A and Oil B effectively increased the TBN of the lubricating oil composition as measured by ASTM D-4739, without contributing to SASH content.
  • the comparative compound of Synthesis Example 3 having a di-alkyl branching arrangement not according to the present invention gave no significant improvement in TBN. This was so even in the case of Oil D where a greater amount of compound was used (2.00 mass% vs. 1.64 mass%).
  • Oil A and a similar oil containing N,N-di-n-hexyl-4-ethoxyaniline in place of the compound of the invention were tested in the VW-6/AK6 test.
  • This procedure tests compatibility of lubricating oils with Viton fluoroelastomer seal materials.
  • the elongation at break for a reference oil containing neither compound was on average -34.5% compared to a new seal.
  • For Oil A the average was -51% and for the oil containing N,N-di-n-hexyl-4-ethoxyaniline, -64%.
