Definitions
- This invention relates to an overbased metal sulphonate detergent.
- the present invention is therefore concerned with overcoming the compatibility issues between friction modifiers and overbased metal sulphonate detergents in lubricating oil compositions.
- an overbased metal sulphonate detergent having incorporated therein at least one friction modifier including at least one amine group; wherein the friction modifier is selected from: alkoxylated hydrocarbyl-substituted mono-amines and diamines, and hydrocarbyl ether amines; preferably from alkoxylated tallow amines and alkoxylated tallow ether amines; preferably alkoxylated amines containing about two moles of alkylene oxide per mole of nitrogen.
- the friction modifier having at least one amine group is hereinafter known as 'amine-based friction modifier'.
- the overbased metal sulphonate detergent is manufactured in the presence of the amine-based friction modifier so that the friction modifier is incorporated into the detergent.
- US2007/0015672 discloses method of improving compatibility of an overbased detergent
- GB-A-1513441 and EP-A-1018539 disclose the preparation of overbased sulfonate detergents having incorporated therein a polyisobutylene succinimide-amine and aliphatic amide, respectively.
- Friction modifiers are generally long, slender molecules added to lubricants for the purpose of minimizing light surface contacts. They have a polar end (head) and an oil-soluble end (tail).
- the tail is normally a straight hydrocarbon chain including at least 10 carbon atoms, preferably 10-40 carbon atoms, more preferably 12-25 carbon atoms, and even more preferably 15-19 carbon atoms. If the tail is too long or too short, the molecule will not function as a friction modifier. In use, the heads attach to a metal surface and the tails stack side by side.
- the amine-based friction modifier is selected from: alkoxylated hydrocarbyl-substituted mono-amines and diamines, and hydrocarbyl ether amines; preferably from alkoxylated tallow amines and alkoxylated tallow ether amines; with alkoxylated amines containing about two moles of alkylene oxide per mole of nitrogen being the most preferred. Ethoxylated amines and ethoxylated ether amines are especially preferred.
- Such friction modifiers preferably include linear hydrocarbyl groups. Hydrocarbyl groups are predominantly composed of carbon and hydrogen but may contain one or more hetero atoms such as sulphur or oxygen.
- Preferred hydrocarbyl groups range from 12-25 carbon atoms, preferably 15-19 carbon atoms.
- Preferred structures are illustrated by (but not limited to) the two figures below: wherein R is a C 6 to C 28 alkyl group, preferably a C 12 to C 25 alkyl group, X and Y are independently O or S or CH 2 , x and y are independently 1 to 6, p is 2 to 4 (preferably 2), and m and n are independently 0 to 5.
- the alkyl group or groups are sufficiently linear in character to impart friction modifier properties.
- the overbased metal sulphonate detergent is synthesized in the presence of the amine-based friction modifier in order to produce a hybrid system that functions as both a detergent and a friction modifier. Therefore, it may be used in a lubricating oil composition as both the detergent and the friction modifier, which means that a separate, additional friction modifier may not be required.
- the amine-based friction modifier is preferably added to the reaction components after a "'heat-soaking" step.
- a lubricating oil composition comprising oil of lubricating viscosity and the overbased metal sulphonate detergent comprising the above-defined at least one friction modifier having at least one amine group.
- a lubricating oil composition as both a detergent and a friction modifier of the overbased metal sulphonate detergent comprising the at least one friction modifier having at least one amine group.
- a method for preparing the overbased metal sulphonate detergent comprising the above-defined at least one friction modifier having at least one amine group; the method comprising the following steps:
- the engine is preferably an automotive engine, especially a gasoline engine.
- the alkyl arene sulphonic acid is preferably an alkylbenzene sulphonic acid.
- the alkali metal or alkaline earth metal base is preferably calcium hydroxide.
- a detergent is an additive that reduces formation of piston deposits, for example high-temperature varnish and lacquer deposits, in engines; it normally has acid-neutralising properties and is capable of keeping finely divided solids in suspension.
- Most detergents are based on metal "soaps"; that is metal salts of acidic organic compounds, sometimes referred to as surfactants.
- Detergents generally comprise a polar head with a long hydrophobic tail, the polar head comprising a metal salt of an acidic organic compound.
- a metal base such as an oxide or hydroxide
- an acidic gas such as carbon dioxide
- Overbased metal sulphonate detergents are preferably formed from a mixture of a sulphonic acid, a hydrocarbon solvent, an alcohol, water and a stoichiometric excess of a metallic base (preferably calcium hydroxide) above that required to react with the sulphonic acid.
- the mixture is overbased (carbonated) with an overbasing agent which provides a source of base.
- the process involves adding the reagents to a reactor and injecting the overbasing agent into the reactor until most or all of the metal compound has been carbonated.
- the carbonation step is followed by a "heat-soaking" step in which the mixture is maintained, without addition of any further chemical reagents, in a selected temperature range (or at a selected temperature), which is normally higher than the temperature at which carbonation is effected, for a period before any further processing steps are carried out.
- the amine-based friction modifier is preferably added to the overbased detergent after the "heat-soaking" step.
- overbasing agents examples include carbon dioxide, a source of boron (for example, boric acid), sulphur dioxide, hydrogen sulphide, and ammonia.
- Preferred overbasing agents are carbon dioxide or boric acid, or a mixture of the two.
- the most preferred overbasing agent is carbon dioxide and, for convenience, the treatment with overbasing agent will in general be referred to as "carbonation". Unless the context clearly requires otherwise, it will be understood that references herein to carbonation include references to treatment with other overbasing agents.
- part of the basic metal compound remains uncarbonated.
- up to 15 mass % of the basic calcium compound remains uncarbonated, especially up to 11 mass %.
- Carbonation is effected at less than 100°C. Typically the carbonation is effected at at least 15°C, preferably at least 25°C.
- carbonation is carried out at less than 80°C, more advantageously less than 60°C, preferably at most 50 °C, more preferably at most 40°C, and especially at most 35°C.
- the temperature is maintained substantially constant during the carbonation step, with only minor fluctuations.
- both or all carbonation steps are preferably carried out at substantially the same temperature, although different temperatures may be used, if desired, provided that each step is carried out at less than 100°C.
- Carbonation may be effected at atmospheric, super-atmospheric or subatmospheric pressures. Preferably, carbonation is carried out at atmospheric pressure.
- the carbonation step is followed by a "heat-soaking" step in which the mixture is maintained, without addition of any further chemical reagents, in a selected temperature range (or at a selected temperature), which is normally higher than the temperature at which carbonation is effected, for a period before any further processing steps are carried out.
- the mixture is normally stirred during heat-soaking.
- heat-soaking may be carried out for a period of at least 30 minutes, advantageously at least 45 minutes, preferably at least 60 minutes, especially at least 90 minutes.
- Temperatures at which heat-soaking may be carried out are typically in the range of from 15°C to just below the reflux temperature of the reaction mixture, preferably 25°C to 60°C: the temperature should be such that substantially no materials (for example, solvents) are removed from the system during the heat-soaking step.
- substantially no materials for example, solvents
- the amine-based friction modifier is preferably added to the detergent after the heat-soaking step.
- Products of reduced viscosity may be obtained by employing one or more further additions of basic calcium compound and subsequent carbonation, each carbonation step advantageously being followed by a heat-soaking step.
- Basic metal compounds include metal oxides, hydroxides, alkoxides, and carboxylates. Calcium oxide and, more especially, hydroxide are preferably used. A mixture of basic compounds may be used, if desired.
- the mixture to be overbased by the overbasing agents should normally contain water, and may also contain one or more solvents, promoters (such as alkanols, preferably methanol) or other substances commonly used in overbasing processes.
- solvents such as water, and may also contain one or more solvents, promoters (such as alkanols, preferably methanol) or other substances commonly used in overbasing processes.
- promoters such as alkanols, preferably methanol
- suitable solvents are aromatic solvents, for example, benzene, alkyl-substituted benzenes, for example, toluene or xylene, halogen-substituted benzenes, and lower alcohols (with up to 8 carbon atoms).
