  • a "flow improver” sometimes referred to as a pour point depressant, is a compound that influences the crystallization of wax in the lubricating oil as the temperature is decreased.

  • Preferred amine compounds contain a combined total of from about 18 to about 30 carbon atoms.
  • Preparation of the amine compounds, when X is oxygen and m is 1 is, for example, by a multi-step process where an alkanoi is first reacted, in the presence of a catalyst, with an unsaturated nitrile such as acrylonitrile to form an ether nitrile intermediate.
  • the intermediate is then hydrogenated, preferably in the presence of a conventional hydrogenation catalyst, such as platinum black or Raney nickel, to form an ether amine.
  • the ether amine is then reacted with an alkylene oxide, such as ethylene oxide, in the presence of an alkaline catalyst by a conventional method at a temperature in the range of about 90-150°C.
  • Another method of preparing the amine compounds is to react a fatty acid with ammonia or an aikanol amine, such as ethanolamine, to form an intermediate which can be further oxyalkylated by reaction with an alkylene oxide, such as ethylene oxide or propylene oxide.
  • a process of this type is discussed in, for example, U.S. Patent No. 4,201,684.

  • the amine's hydrocarbyl chain length, the saturation of the hydrocarbyl chain, and the length and position of the polyoxyalkylene chains can be varied to suit specific requirements. For example, increasing the number of carbon atoms in the hydrocarbyl radical tends to increase the amine's melting temperature and oil solubility, however, if the hydrocarbyl radical is too long, the amine will crystallize from solution. Decreasing the degree of saturation in the hydrocarbyl radical, at the same carbon content of the hydrocarbyl chain, tends to reduce the melting point of the amine. Increasing the amount of alkylene oxide, to lengthen the polyoxyalkylene chains, tends to increase the amine's water solubility and decrease its oil solubility.

  • R" is preferably straight chained.
  • the R" hydrocarbyl group includes predominantly hydrocarbyl groups as well as purely hydrocarbyl groups. The description of these groups as predominantly hydrocarbyl means that they contain no non-hydrocarbyl substituents or non-carbon atoms that significantly affect the hydrocarbyl characteristics or properties of such groups relevant to their uses as described here.

Use of alkenyl succinimides which have been treated with an inorganic acid of phosphorus (or an anhydride thereof) and a boronating agent are also suitable for use in the compositions of this invention as they are much more compatible with elastomeric seals made from such substances as fluoro-elastomers and silicon-containing elastomers.

  • Dispersants may be post-treated with many reagents known to those skilled in the art. (see, e.g., U.S. Pat. Nos. 3,254,025, 3,502,677, and 4,857,214).
  • Suitable antioxidants are amine-type and phenolic antioxidants.
  • the amine-type antioxidants include phenyl alpha naphthylamine, phenyl beta naphthylamine, diphenylamine, bis- alkylated diphenyl amines (e.g., p,p'-bis(aikylphenyl)amines wherein the alkyl groups contain from 8 to 12 carbon atoms each).
  • Phenolic antioxidants include stericaily hindered phenols (e.g., 2,6-di-tert-butylphenol, 4-methyl-2,6-di-tert- butylphenol, etc.) and bis-phenols (e.g., 4,4'- methyienebis(2,6-di-tert- butylphenol), etc.) and the like.
  • the additive concentrates of this invention will contain the viscosity modifier, friction modifier, and other desired additives in a natural and/or synthetic lubricating oil, in relative proportions such that by adding the concentrate to a larger amount of a suitable natural and/or synthetic oil the resulting fluid will contain each of the ingredients in the desired concentration.
  • the concentrate may contain a synthetic oil as the lubricating oil if the desired final composition contains a lesser amount of synthetic oil relative to the mineral oil.
  • the concentrate typically will contain between 25 to 100, preferably from 65 to 95, most preferably from 75 to 90 weight percent of the viscosity modifier, friction modifier, other desired additives, and synthetic and/or natural oil.
  • the additive package contained conventional amounts of a succinimide dispersant, antioxidants, antiwear agents, friction modifiers, a corrosion inhibitor, an antifoamant, and a diluent oil.
  • Each ATF contained Exxon solvent 100 neutral oil ( «4.0 mm2/s (cSt) at 100°C) (FN 1365) and PAO-4 ( «4.0 mm2/s (cSt) at 100°C) (1-decene oligomer).
  • the ratio of 100 neutral oil to PAO-4 was chosen such that a properly treated blend could achieve a -40°C viscosity of less than 10,000 cP, and a kinematic viscosity at 100 ⁇ C of at least 3.8 mm 2 /s (cSt).
  • BLENDS 1-19 contained diisooctyl adipate as a seal swelling agent.
  • Table 1 The compositions of the blends and their measure kinematic viscosities at 100°C and Brookfield viscosities at -40°C are shown in Table 1.
  • the flow improvers used are identified in Table 1 by their trade names.
  • the PARAFLOW® products are fumarate-vinyl acetate copolymers with varying sidechain lengths.
  • VISCOPLEX® products are polymethacryiates of varying molecular weights and sidechain lengths.
  • BLEND 1 in Table 1 is a 'blank' in that it contains no flow improver. As shown, this blend has a very high -40°C Brookfield viscosity of 87,000 cP which is totally unexpected for an ATF containing over 40% of a synthetic lubricating oil, PAO-4.
  • BLENDS 8 and 9 show the results obtained when an ineffective flow improver is used. While not wishing to be bound to any particular theory, it is believed that the PARAFLOW 394 flow improver used in BLENDS 8 and 9 polymerizes with the wax present in the natural lubricating oil to form a crosslinked wax gel which causes viscosities at -40°C higher than those of the 'blank'.
  • Fluid viscosity at -40°C is not only a function of flow improver type but also flow improver concentration.
  • Table 2 shows a series of blends using three effective flow improvers for this system. Table 2 shows that for each flow improver there is an optimum treat rate to obtain the lowest -40°C Brookfield viscosity (see BLENDS 23, 27, and 31 ). While not wishing to be bound to any particular theory, it is believed that this result occurs because there is not enough flow improver at very low concentration to disrupt crystallization of all the wax and consequently the Brookfield viscosities are elevated compared to the minimum Brookfield viscosity obtainable in these systems (see BLENDS 24, 28, 29 and 34).
  • the flow improver merely adds viscosity at -40°C since the flow improver is itself a polymer (see BLENDS 21 , 26 and 30). Therefore, for each ATF system, the type and concentration of the most effective flow improver must be determined.
  • Table 3 shows a number of ATF blends made using the Exxon solvent 100 neutral oil that produce fluids that completely meet very stringent targets, i.e., kinematic viscosity at 100°C of no less than 3.8 mm 2 /s (cSt) and Brookfield viscosities at -40°C less than 5,000 cP.
  • BLENDS 37, 39, 42, 43, 44, 45, and 46 fully meet these stringent requirements, this is only possible due to the incorporation of non-wax gelling flow improvers.
  • compositions of this invention work in a variety of lubricating oils.
  • Table 4 shows blends meeting the stringent requirements described in Example 3, but with various natural lubricating oils: Exxon 100 neutral ( «4.0 mm 2 /s (cSt) at 100°C); Exxon 75 neutral (*3.0 mm 2 /s (cSt) at 100°C); Chevron RLOP 100 neutral — a severely hydrotreated and catalyticaily de- waxed basestock having a kinematic viscosity of *4.1 mm2/s (cSt) at 100°C; and Imperial MXT-5 — a basestock produced by isomerizing slack wax having a kinematic viscosity of «3.8 mm2/s (cSt) at 100°C.
  • BLENDS 47, 52, 56, 60 and ail show the unexpectedly high -40°C Brookfield viscosities exhibited by mixtures of mineral oils and synthetics without flow improvers.
  • Table 4 shows that any of these natural lubricating oils, when treated with synthetic components and flow improvers, can be made to meet the most restrictive requirements of high and low temperature viscometrics. This is exemplified by BLENDS 49, 51 , 53, 55, 57, 59, 61 , and 63, all of which have kinematic viscosities at 100°C of at least 3.8 mm2/s (cSt) and Brookfield viscosities at - 40°C under 5,000 cP.
