Definitions
- This invention is directed to hydroxy polyether polyamines, to fuel compositions and lubricating oil compositions containing these compounds and to their use
- Deposits adversely affect the operation of the vehicle. For example, deposits on the carburetor throttle body and venturies increase the fuel to air ratio of the gas mixture to the combustion chamber thereby increasing __ the amount of unburned hydrocarbon and carbon monoxide discharged from the chamber.
- the high fuel-air ratio also reduces the gas mileage obtainable from the vehicle.
- each engine when new, requires a certain minimum octane fuel in order to operate satisfactorily without pinging and/or knocking. As the engine is operated on any gas ⁇ oline, this minimum octane increases and, in most cases, if the engine is operated in the same fuel for a prolonged period, will reach an equilibrium. This is apparently caused by an amount of deposits in the combustion chamber. Equilibrium is typically reached after 5000 to 15000 miles of automobile operation.
- octane requirement increase in particular engines used with commercial gasolines will vary at equi- librium from 5 or 6 octane units to as high as 12 or
- OMPI disclose* lead-containing fuel compositions having reduced ORI properties.
- the ORI problem is compounded by the fact that the most common method for increasing the octane rating of unleaded gasoline is to increase its aromatic content. This, however, eventually causes an even greater increase in the octane requirement.
- some of presently used nitrogen-containing compounds used as deposit-control additives and their mineral oil or polymer carriers may also significantly contribute to ORI in engines using unleaded fuels.
- the second complicating factor relates to oil solubility of the fuel additives.
- Fuel additives due to their higher boiling point over gasoline itself, tend to accumulate on surfaces in the combustion chamber. This accumulation of the additive eventually finds its way into the lubricating oil via a "blow-by" process. In some cases this process may be of no concern as the fuel additives will be inert and compatible in the oil.
- the additive is incompatible in the lubrica ⁇ ting oil a serious problem develops as the accumulation of the additive results in an emulsion-like sludge which is detrimental to efficient operation. Therefore, it is particularly desirable that the gasoline additive be oil compatible.
- the present invention also relates to lubricating oil compositions containing hydroxy polyether polyamines which contribute dispersancy and detergency to the compositions.
- Lubricating oil compositions particularly for use in internal combustion engines, have long performed many functions other than simply lubricating moving parts. Modern-day, highly compounded lubricating oil compositions provide anti-wear, anti-oxidant, extreme- pressure and anti-rust protection in addition to main- taining the cleanliness of the engine by detergency and dispersancy. Many lubricating oil additives are well known for accomplishing these functions. For maintaining engine cleanliness, a well-known class of ashless deter ⁇ gents which have been found to be particularly useful are polyoxyalkylene carbamates.
- Polyether a ine-type fuel additives for deposit control and lubricating oil dispersancy are well-known but have traditionally been surfactant-type molecules having a large, non-polar hydrophobic end or "tail", for instance, a hydrocarbyl capped polyether moiety, and a polar, hydrophilic amine or polyamine end. Examples of these -type of compositions may be found in U.S. Patent No. 4,247,301; U.S. Patent No. 4,160,648; and applications U.S. Serial Nos. 403,606 and 403,607, Campbell, both filed July 7, 1982 and applications U.S. Serial Nos, 499,131 and 499,132, both filed May 31, 1983.
- Additives are provided which, when added to fuels or used as fuel concentrates, are effective in cleaning and maintaining the cleanliness of engine intake systems and when added at from about 0.01 to about 10 weight percent to lubricating oil, are effective in providing dispersancy and detergency to the oil.
- the additives consist of certain fuel and lubricating oil soluble hydroxy polyoxyalkylene amines or polyamines These additives have the following general formula:
- R' ' has at least 2 carbon atoms
- compositions may be either mono or polyamines, but polyamines are preferred.
- the additive compounds have molecular weights of >from about 500 to
- this invention is based on my discovery that the hydrophobic portion of a polyether polyamine fuel additive may contain an "uncapped" hydroxy1 group, provided that the polyether is a co-polymer and that the portion of the co-polymer having the hydroxyl group has more carbon atoms per unit than the other portion of the block co-polymer.
- a preferred compound is composed of a block co-polymer in which the hydroxyl-containing portion is composed of pol (butylene glycol) and the other portion is composed of poly(ethylene glycol).
- R 1 has at least 2 carbon atoms, and that R * ' , R * ' ' and R 1V are H.
- the compositions are selected to provide solubility in fuel compositions and deposit control activity without contributing to octane require ⁇ ment increase (ORI) .
- the desired concentration of the additive will vary according to fuel
- the concentration will be from about 250 parts per million (ppm) by weight to about 5000 ppm by weight.
- the preferred concentration is from about 300 ppm to 2000 ppm.
- the additive compositions may be used as concentrates, and could be used 'as additive to fuels subsequent to their prepara ⁇ tion.
- the weight percent of these additives will usually range from about 0.3 to 50 weight percent.
- the concentrate would ordinarily comprise an inert stable olephilic organic solvent and the carrier of said solvent boiling in the range of from about 150° to 400°F and the concentrate would preferably contain from about 10 to 50 weight percent of the additive compound.
- the specific compositions are selected to provide solubility in lubricating oil compositions with dispersant activity, without contributing to depos >it formation in the lubricating oil composition.
- the addition to the oil of from about 0.01 to about 10 weight percent of an additive of this invention is effective in providing dispersancy and detergency to the oil.
- oils which find use in this invention are oils of lubricating viscosity derived from petroleum or synthetic sources. Oils of lubricating viscosity normally have viscosities in the range of 35 to 50,000 Saybolt Universal Seconds (SUS) at 37.6°C and more usually from about 50 to 10,000 SUS at 37.6°C.
- base oils are naphthenic bases, paraffin base and mixed base mineral oils, synthetic oils; for example, alkylene polymers, such as the polymers or propylene, butylene, etc., and mixtures thereof.
- oils besides the subject additives are such additives as dispersant/detergents, rust inhibitors, antioxidants, oiliness agents, foam inhibitors, viscosity index improvers, pour point depres- sants, etc.
- these other additives will be present in amounts of from about 0.5 to 15 weight percent of the total composition.
- each of the addi- tives will be present in the range from about 0.01 to
- additive compositions may be used as lubricating oil concentrates, and could be used as additive to lubricating oils subsequent to their preparation.
- weight percent of these additives will usually range from about 10 to 90 weight percent.
- the additive compounds can be prepared by a variety of known processes.
- an appropriate hydroxy-substituted amine containing both the desired amino moiety and the appropriate hydroxy- ter inated alkyl moiety, is first reacted to form an
- a halohydroxyalkylene preferably chlorohydroxyalkylene is first reacted at the hydroxy terminus with an appropriate alkylene oxide.
- the halo group is then reacted with an amine or polyamine, preferably in excess to yield the hydroxy poly(oxy- alkylene) amines or polyamines of this invention.
- Suitable halohydroxyalkylenes include
- the resulting slurry was heated to approx. 90°C and 100 ml (1.16 moles) of distilled 1,2-epoxybutane was added over 30 minutes. After this addition, the reaction was stirred with heating for 30 minutes and then cooled to room temperature and stirred for 16 hours.
- the reaction was quenched by adding approx. 200 ml of t-butanol and stirring 30 minutes, followed by approx. 50 ml of water.
- the reaction was diluted with 300 ml ether and extracted with two 100 ml portions of water.
- a Waukesha CFR single-cylinder engine is used. The run is carried out for 15 hours, at the end of which time the intake valve is removed, washed with hexane and weighed. The previously determined weight of the clean valve is subtracted from the weight of the valve. The difference between the two weights is the weight of the deposit with a lesser amount of deposit measured connoting a superior additive.
- the operating conditions of the test are as follows: water jacket temperature 100°C; manifold vacuum of 29.5 cm Hg, intake mixture temperature of 50.2°C; air-fuel ratio of 12; ignition spark timing of 40°BTC; engine speed is 1800 rpm; and the crankcase oil is a commercial 30 oil. The amount of carbonaceous deposit in milligrams on the intake valves is measured and reported in the following Table I.
