Definitions
- CIOM 3/32 are obtained by sulfurizing a mixture of at least one CIOM COM 7/36 fatty acid ester (preferably an oil such as soybean oil), I at least one C aliphatic olefin (preferably an a-ole- [58] Field of Search 252/48.6, 395, 72/42 and Optionally at least one fatty acid (preferably [56] References Cited unsaturated) UNITED STATES PATENTS 11 Claims, No Drawings 1.974299 9/l934 Churchill 252/48.6
- This invention relates to new compositions of matter suitable for use as lubricant additives, and to methods for their preparation. More particularly, it relates to sulfurized compositions prepared by reacting, at about 100250C., sulfur with a mixture comprising (A) 100 parts by weight of at least one fatty acid ester, (B) about -50 parts by weight of at least one fatty acid, and (C) about -400 parts by weight of at least one aliphatic olefin containing about 8-36 carbon atoms.
- Sulfurized sperm oil has long been used as a lubricant additive, particularly to improve extreme pressure properties while providing excellent slip and some degree of rust inhibition in motor oils, gear lubricants, cutting and rolling oils.
- the United States Government has recently taken action to prevent the killing of whales, from which sperm oil is obtained, to avoid their becoming extinct.
- the only source of sperm oil has therefore dried up and it has become necessary to find substitutes for the sulfurized derivatives thereof, which can be cheaply and efficiently produced and which provide the same advantageous properties to lubricants.
- a principal object of the present invention is to provide a method for producing useful lubricant additives.
- a further object is to produce sulfurized lubricant additives which improve extreme pressure properties.
- Still another object is to produce compositions which may be substituted for sulfurized sperm oil as lubricant additives, and which provide the same properties as the sperm oil derivative.
- the method of this invention comprises the reaction of sulfur with a mixture of three reagents.
- Reagent A is at least one fatty acid ester.
- fatty acid refers to acids which may be obtained by hydrolysis of a naturally occurring vegetable or animal fat or oil. These are usually in the C range and include palmitic acid, stearic acid, oleic acid, linoleic acid and the like.
- Fatty acid esters which are useful as reagent A are primarily those with aliphatic alcohols, including monohydric alcohols such as methanol, ethanol, npropanol, isopropanol, the butanols, etc., and polyhydric alcohols including ethylene glycol, propylene glycol, trimethylene glycol, neopentyl glycol, glycerol and the like.
- Particularly preferred are the fatty oils, that is, naturally occurring esters of glycerol with the abovenoted long chain carboxylic acids, and synthetic esters of similar structure.
- fatty oils derived from unsaturated acids especially oleic and linoleic, including such naturally occurring animal and vegetable oils as lard oil, peanut oil, cottonseed oil, soybean oil, corn oil and the like,
- Reagent B is at least one fatty acid as described above. It is usually an unsaturated fatty acid such as oleic or linoleic acid, and may be a mixture of acids such as is obtained from tall oil or by the hydrolysis of peanut oil, soybean oil or the like.
- the amount of reagent B is about 0-50 parts by weight per 100 parts of reagent A; that is, it is an optional ingredient. However, it improves the slip, rust inhibiting and extreme pressure properties of lubricants containing the sulfurized 2 compositions of this invention, and so its presence (generally in the amount of about 2-8 parts by weight) is preferred.
- Reagent C is at least one C aliphatic olefin. About 25-400 parts, usually about 25-75 parts, of reagent C are present per 100 parts of reagent A. Terminal olefins, or a-olefins, are preferred, especially those in C range. Mixtures of these olefins are commercially available and such mixtures are contemplated for use in this invention.
- the reaction mixture may contain other materials. These may include, for example, sulfurization promoters, typically phosphorus-containing reagents such as phosphorous acid esters (e.g., triphenyl phosphite), and surface active agents such as lecithin.
- sulfurization promoters typically phosphorus-containing reagents such as phosphorous acid esters (e.g., triphenyl phosphite), and surface active agents such as lecithin.
- the method of this invention comprises the reaction of a mixture of the above-noted reagents with sulfur at a temperature of about 100-250C., usually about l50-2l0C.
- the weight ratio of the combination of reagents A, B and C to sulfur is between about 5:1 and 15:], generally between about 5:1 and 10:1.
- the sulfurization reaction is effected by merely heating the reagents at the temperature indicated above, usually with efficient agitation and in an inert atmosphere (e.g., nitrogen). If any of the reagents, especially reagent C, are appreciably volatile at the reaction temperature, the reaction vessel may be sealed and maintained under pressure. It is frequently advantageous to add the sulfur portionwise to the mixture of the other reagents. While it is usually preferred that the reaction mixture consists entirely of the reagents previously described, the reaction may also be effected in the presence of an inert solvent (e.g., an alcohol, ether, ester, aliphatic hydrocarbon, halogenated aromatic hydrocarbon or the like) which is liquid within the temperature range employed.
- an inert solvent e.g., an alcohol, ether, ester, aliphatic hydrocarbon, halogenated aromatic hydrocarbon or the like
- reaction temperature is relatively high, e.g., about 200C.
- a lower reaction temperature e.g., about l50-l70C.
- the reaction sometimes requires a longer time at lower temperatures and an adequate sulfur content is usually obtained when the temperature is at the high end of the recited range.
- insoluble by-products may be removed by filtration, usually at an elevated temperature (about -120C.).
- the filtrate is the desired sulfurized product.
- EXAMPLE 1 A mixture of 60 parts of commercial C1540 a-olefins and parts of lard oil is heated to C, under nitrogen, and 12 parts of sulfur is added. The mixture is heated at l65200C. and an additional 6.5 parts of sulfur is added. Heating is continued for 4 hours, after which the mixture is cooled to 100C. and filtered to yield the desired product which contains 9.0% sulfur.
- EXAMPLE 2 To a mixture of 100 parts of soybean oil and 50 parts of l-hexadecene at C., under nitrogen, is added over 20 minutes, with stirring, 20.6 parts of sulfur. An exothermic reaction occurs which causes the temperature to rise to 200C. It is heated at 200C. for 6 hours, cooled to 1 10C. and filtered to yield the desired product which contains 1 1.1% sulfur.
- EXAMPLE 3 A mixture of 100 parts of soybean oil and 50 parts of commercial C a-olefins is heated to 175C. under nitrogen and 17.4 parts of sulfur is added gradually, whereupon an exothermic reaction causes the temperature to rise to 205C. The mixture is heated at 188-200C. for hours, allowed to cool gradually to 90C. and filtered to yield the desired product containing 10.13% sulfur.
- EXAMPLE 4 Following the procedure of Example 3, a sulfurized product is prepared from 100 parts of soybean oil, 50 parts of commercial C oz-olefins and 17.4 parts of sulfur. It contains 10.1% sulfur.
- EXAMPLE 7 Following the procedure of Example 3, a product containing 10.16% sulfur is obtained from 100 parts of cottonseed oil, 33.3 parts of commercial C oz-olefins and 15.6 parts of sulfur.
- EXAMPLE 8 Following the procedure of Example 3, a product containing 8.81% sulfur is obtained from 100 parts of a triglyceride having an iodine number of 85-95, 25 parts of commercial C a-olefins and 14.5 parts of sulfur.
- EXAMPLE 9 A mixture of 100 parts of soybean oil, 50 parts of commercial C aolefins, 1.17 part of triphenyl phosphite and 17.4 parts of sulfur is heated for 16 hours at 145165C., under nitrogen. It is then cooled to room temperature, reheated to 100C. and filtered with the addition of a filter aid material. The filtered product contains 10.13% sulfur.
- EXAMPLE 10 A mixture of 100 parts of soybean oil, 3.7 parts of tall oil acid and 46.3 parts of commercial C1548 a-olefins is heated to 165C. under nitrogen, and 17.4 parts of sulfur is added. The temperature of the mixture rises to 191C. It is maintained at 165200C. for 7 hours and is then cooled to 90C. and filtered. The product contains 10.13% sulfur.
- EXAMPLE 1 1 Following the procedure of Example 10, a product containing 10.39% sulfur is obtained from 100 parts of soybean oil, 4 parts of tall oil acid, 46.3 parts of commercial C a-olefins and 20.6 parts of sulfur.
- EXAMPLE 12 Following the procedure of Example 10, a product containing 10.6% sulfur is obtained from parts of soybean oil, 5.25 parts of tall oil acid, 44.8 parts of commercial C a-olefins and 17.4 parts of sulfur.
