Definitions
- This invention relates to fuels and more particularly to leaded gasolines for high-compression, spark ignition engines.
- various scavenging agents have been added to the fuel to change the form of the tetraethyl lead decomposition products to those which are more volatile and thus less likely to be deposited within the engine.
- various volatile alkyl halides such as ethylene dibromide and/ or ethylene dichloride have been used with tetraethyl lead to produce the corresponding halides of lead-which are more volatile than the oxides.
- phosphate having the 3 7 wherein R, R and R are alkyl groups containing about 1 to about carbon atoms, R and R are selected from the group consisting of hydrogen and alkyl groups con taining about 1 to about 3 carbon atoms and x is an integer from 1 to 2.
- the latter compound for example, is completely soluble in gasoline at 25 C., and has a solubility in water at 25 C. of only about 0.11 percent.
- R, R and R" in the struc tural formula shown hereinabove can be either alike or different.
- tri(alkoxyalky1) phosphates which can be used in accordance with our invention are I Tri(methoxyethyl) phosphate Tri(1-methoxy-2-propyl) phosphate Tri-(Lmethoxy-l-butyl) phosphate T ri(1-methoxy-2-butyl) phosphate Tri(2-metl1oxy-3-butyl) phosphate Tri(2-methoxy-'1-pentyl) phosphate Tri(3-methoxy-2-hexy-l) phosphate Tri(3-meth0xy-4-heptyl) phosphate Tri(4-methoxy-5-octyl) phosphate Di(rnethoxyethyl) propoxyethyl phosphate Di(methoxyethyl) butoxyethyl phosphate Di(propoxyethyl) methoxyethyl phosphate Di(propoxyethyl) butoxyeth
- the product is a colorless liquid and has an index of refraction of 1.4352 at 20 C.
- the phosphorus content of the product so obtained is 11.11 percent as compared with the theoretical amount of 11.37,.
- the yield is about.
- the amount of tri(alkoxyalkyl) phosphate required to impart improved preignition characteristics to the gasoline fuels, i.e., hydrocarbon mixtures boiling in the gasoline boiling range, depends upon the tetraethyl lead content of the particular fuel encountered, and upon the particular tri(alkoxyalkyl) phosphate which is selected. For this reason, the amount is more significant and can be more accurately expressed in terms of that which is theoretically required to convert the lead introduced into the fuel in the form of tetraethyl lead to lead orthophosphate. While improved results can be obtained with very small amounts, amounts corresponding to at least about 0.1 times that theoretically required to convert the lead to lead phosphate are preferred.
- Mos-t gasolines on the market today contain between about one and about three cubic centimeters of tetraethyl. lead per gallon of gasoline. Based upon a gasoline having a gravity of about 54 API and containing about one cubic centimeter of tetraethyl lead, we have determined that the amount of the tri- (butoxyethyl) phosphate corresponding to 0.1 to 1.0 theories is about 0.0047 to about 0.047 percent by weight based on the gasoline.
- the tri(butoxyethyl) phosphate for 0.1 to 1.0 theories is about 0.014 to about 0.14 percent by weight.
- the normally useful concentration range for a 54 API gasoline containing about 1 to about 3 cubic centimeters of tetraethyl lead is about 0.0047 to about 0.14 percent.
- greater concentrations can be employed to advantage in some instances, no additional benefits with respect to preignition are achieved by the use of greater concentrations.
- about-0.003 to about 0.45 weight percent of the tri(-alkoxyalkyl) phosphate is usually suflicient to achieve a satisfactory reduction in the engine preignition tendencies of the fuel.
- the amount within this range should, of course, be suflicient toincorporate between about 0.1 and about 1.0 times that theoretically required to convert the lead to lead phosphate.
- pounds may vary from one compound to another. Another reason is that the molecular Weight of one com-' pound may be twice the molecular weight of another compound,-so that to obtain an equivalent amount 04? phosphorus when using the compound having the greater molecular weight, one is required to use twice the amount In any event, the amountof the tri(a1koxyaikyl) phosphate used is suflicient of compound on a weight basis.
- the tri(alkoxyalky1) phosphate can be either chemically pure or it can comprise a commercial product which may contain a small amount of the alkoxyalkanol from which the corresponding tri(alkoxy alkyl) phosphate was prepared or other neutral impurities.
- a small amount of butoxyethanol can be present without deleteriously affecting the improved preigniu'on characteristicsof the fuel.
- the gasoline fuel composition to which the tri(alkoxyalkyl) phosphate is added comprises a mixture of hydrocarbons boiling in the gasoline boiling range having a motor octane number (leaded) i of at least about 85 and a research octane number (leaded) of at least about 95.
- the mixture of hydrocarbons can be obtained by at least one of the petroleum conversion processes including cracking, alkylation, aromatization, cyclization, isomerizatiorn, hydrogenation, dehydrogenation, hydroisomerization, polymerization, hydrodesulfurization, reforming, hy-
- a preferred gasoline fuel composition comprises a blend of hydrocarbons obtained by catalytic cracking, Platfocrming and alkylation processes.

- gasoline improvement agents including upper cylinder lubricants, corrosion and oxidation inhibitors, conventional alkyl halide lead scavenging agents, alcoholic anti-stalling agents,,metal deactivators, dehazing .agents, anti-rust additives, other ignition control agents,
- an upper cylinder lubricant When an upper cylinder lubricant is employed it is genorally used in an amount of from about 0.25 to about 0.75
- This oil should be a light lubricating oil distillate, e.g., one having a viscosity at F. of from about 50 to about 500 Saybolt Universal'seconds, e.g., about 100 SUS.
- lubricating distillates obtained from Coastal or naphthenic type crudeoils are preferred because of their superior solvent properties.
- the lubricating oil can be solvent-treated, acid-treated, or'otherwise refined.
- any of the conventional inhibitors can be utilized.
- the alkylated phenols e.g., 2,4,o-tni-tertiary-butylphenol, 2,6-di-tertiarybutyl-4-methylphenol, 2,2-bis(2-hydroxy-3-tertiary-butyl- 5-methylphenyl) propane and bis(2-hydroxy-3-tertiarybutyd-S-methylphenyl) methane, because of their hydrocarbon-solubility and water-insolubili-ty characteristics are preferred oxidation inhibitors.
- Such inhibitors when used are incorporated in the gasoline fuel composition in of course,- that the optimum amounts. of from about 0.001 to about 0.02 percent by weight of the composition, e.g., 0.007 weight percent.
- Exemplary of other specific improvement agents which we can use are N,N-disalicylidene-1:Z-diaminopropane as a metal deactivator and the cocoamine salt of isoamyl octyl acid orthophosphate as a rust inhibitor agent.
- metal ,deactivator is generally used in small amounts of the, order of about 0.0003 to about 0.001 percent by weight based on the fuel composition.
- the rust" inhibitor is generally'used in small amounts ofthe order of about 0.002'to about 0.008 percent by weight based on the fuel composition.
- cocoamine salt of isoamyl octyl. acid orthophosphate and its preparation are fully described in U.S.

- the proportions of the constituents in such a gasolinebenefiting concentrate may vary depending upon the characteristics of the base gasoline to which the concentrate is to be added as well as the compression ratio of the engine in which the gasoline is to be used. Good results can be obtained, however, with a composition consistingof about 23 to about 60 percent by weight of tetraethyl lead, about 13 to about 36 percent by weight of a mixture of ethylene halides and about 3 to about 63 percent by weight of a -tn'(alkoxyalkyl) phosphate, the

- One such commercially available product consists of about 61.5 percent by'weight of tetraethyl lead, about 17.9 percent by Weight of ethylene dibromid'e and about 18.8 percent by weight of ethylene dichloride.
- the gasoline-benefiting concentrate thus prepared exhibited no deterioration upon prolonged storage in the dark at room temperature.
- the amount of the gasoline-benefiting concentrate added to gasoline will vary depending upon the octane improvement desired; Ordinarily, however, the concentrate is added in an amount sufficient to incorporate between about one and about three cubic centimeters of tetraethyl lead in a gallon of gasoline.
- tn'(alkoxyalkyl) phosphates of this invention are utilized primarily as preignition agents, they are additionally useful in that they give increased valve life and spark plug life andthey impart valuable anti-rust, oxidation stability and anti-stalling properties to gasoline compositions when used in preignition-inhibiting amounts.

- Example VI composition The data in Table III clearly indicate that the deposits formed in the combustion chambers of each of the test engines was less when using a gasoline containing a tri- (alkoxyalkyl) phosphate than when using the base gasoline alone. While the addition of an upper cylinder lubricant gave an increase in deposits in some tests the deposits were still less than those obtained with the base gasoline alone.

- the improved anti-stalling characteristics were determined in a 1954 Oak operating with an intake air temperature of 35 to 40 F., and a relative humidity of percent. In making the determinations, the engine was cold when started.
