Abstract
Presence of an additive in a hydrocarbon fluid e.g. fuel or lubricant is detected by mixing (i) the fuel or lubricant (ii) at least one additive, and (iii) at least one indicator for the additive in an amount less than an amount required to discolor the fuel or lubricant; and (b) analyzing said hydrocarbonaceous composition for the presence of said indicator. Additive is e.g. an octane improver and indicator is a blue whitener dye. A concentrate for addition to the hydrocarbon fluid comprises additive plus an indicator for the additive in amounts which do not discolor the fluid.
Description
ADDITIVE INDICATORS FOR HYDROCARBONACEOUS FLUIDS
This invention relates to methods and compositions for detecting the presence of additives in hydrocarbonaceous fluids such as fuels and lubricants.
Until now, it has been difficult to determine in the field whether or not any particular hydrocarbonaceous fluid contains an additive. Analysis techniques for the determination of the presence of such additives often time require the use of expensive analytical equipment or may involve destructive testing of the fluid.
Such analytical techniques are not suitable for field use to detect the presence of additives in hydrocarbonaceous fluids and are frequently quite costly. There is a need therefore for a simple, reliable method for detecting the presence of a wide variety of additives in hydrocarbonaceous fluids without the need for expensive analytical equipment or procedures.
It has now been discovered that additives in hydrocarbonaceous fluids can be detected by a method which comprises (a) forming a hydrocarbonaceous composition containing (i) fuel or lubricant, (ii) at least one additive, and (iii) at least one additive indicator dye in an amount less than an amount required to discolor the fuel or lubricant, and (b) analyzing the hydrocarbonaceous composition for the presence of the additive indicator.
In another embodiment, this invention provides a fuel composition comprising (a) fuel, (b) fuel additive, and (c) an amount of at least one additive indicator, which amount is less than the amount required to discolor the fuel composition.
In yet another embodiment, this invention provides a hydrocarbonaceous fluid additive concentrate comprising (a) additive, and (b) an amount of at least one additive indicator, which amount is less than the amount required to discolor a hydrocarbonaceous fluid containing the additive concentrate.
In a preferred embodiment, this invention provides a method for indicating the presence of additives in hydrocarbonaceous fluids which comprises: (a) forming a hydrocarbonaceous fluid composition by admixing (i) fuel or lubricant, (ii) one or more additives, and (iii) one or more additive indicators; (b) providing a field test method for detecting the presence of the additive indicator in the fluid composition; and (c) analyzing the fluid composition by the field method. It is highly desirable that the additive indicator used be essentially innocuous to the fluid composition; that the amount of additive indicator be less than the amount required to discolor the fluid composition; and that at least a portion of the additive indicator be readily removable from the fluid composition by the field method.
The method of this invention can be used with a wide variety of hydrocarbonaceous fluids such as fuels and lubricants for the determination of the presence of additives which may be added to such fluids. Hydrocarbonaceous fluids useful in the method and compositions of this invention include mineral and synthetic lubricants and base oils such as gear oils, hydraulic oils, automatic transmission fluids, brake fluids, and power steering fluids, and hydrocarbonaceous fuels such as fuels boiling in the gasoline boiling range, distillate fuels boiling in the diesel fuel range, jet fuels, marine fuels, and fuel oils.The particular fuel or lubricant used in the method and composition of this invention is not critical provided (1) the fuel or lubricant is not discolored by the additive indicator when the additive indicator is used in an amount which can be detected by the method of this invention and the amount is not sufficient to discolor the fuel or lubricant; (2) the additive indicator is sufficiently soluble in the fuel or lubricant; and (3) the fuel or lubricant is capable of being separated from the additive indicator by the method disclosed herein.
In a particularly preferred embodiment, the method and compositions of this invention are useful for detecting the presence of one or more additives in fuels. Such additives may be used to provide octane improvement, cetane improvement, induction system deposit control, octane requirement increase control, and emission control to a fuel. While this invention may be used to detect the presence of any one or more additives, fuel additives are generally formulated additives, i.e., additives which contain detergents, dispersants, antioxidants, demulsifiers, corrosion inhibitors, fuel stabilizers, dehazers, friction modifiers, and/or mixtures of any two or more of the foregoing. Hence the additive indicator may be used to detect the presence of an additive package in a fuel.
For lubricants, the methods and compositions of this invention may be used to detect the presence of antioxidants, corrosion inhibitors, antiwear extreme pressure agents, viscosity index improvers, dispersants, detergents, friction modifiers, pour point dispersants, antifoam agents, and/or mixtures of any two or more of the foregoing in the lubricant compositions. As used herein, the term "lubricant" contemplates both mineral and synthetic oleaginous fluids and base oils.
For the purposes of this invention, octane improvement additives may comprise one or more cyclomatic manganese compounds. Particularly preferred cyclomatic manganese compounds include cyclopentadienyl manganese tricarbonyl and methylcyclopentadienyl manganese tricarbonyl, and/or mixtures thereof. Cetane improvement additives include organic nitrates, peresters, and peroxyesters. Such octane and cetane improvers are well known to those skilled in the art.
Detergent/dispersant additives useful with the method and compositions of this invention include metal-containing detergents such as calcium phenols, magnesium phenates, calcium sulfonates, and magnesium sulfonates; and detergent dispersant compositions comprising the reaction product of (i) polyamine and (ii) at least one acyclic hydrocarbyl substituted succinic acylating agent. A particularly preferred detergent/dispersant for fuels comprises (a) a succinimide which is the reaction product of (i) polyamine and (ii) at least one acyclic hydrocarbyl substituted succinic acylating agent; (b) an unhydrotreated poly-a-olefin; and (c) optionally, a mineral oil having a viscosity index of less than 90.
Detergenr/dispersants useful with the compositions and methods of this invention are generally well known, hence no further description is deemed necessary.
Antioxidants useful as additives in combination with hydrocarbonaceous fluids include phenolic antioxidants, amine antioxidants, sulfurized phenolic compounds, and organic phosphites, among others. Particularly preferred for use in the practice of this invention are tertiary butyl phenols, such as 2,6-di-tertbutylphenol, 2,4,6-tri-tert-butylphenol, o-tert-butylphenol, and mixtures thereof.
A wide variety of demulsifiers are available for use in the practice of this invention, including, for example, polyoxyalkylene glycols, oxyalkylated phenolic resins, and like materials. Particularly preferred are mixtures of polyoxyalkylene glycols and oxyalkylated alkylphenolic resins, such as are available commercially from Petrolite Corporation under the TOLAD trademark.
Corrosion inhibitors useful with this invention include a wide variety of materials. Thus, use can be made of dimer and trimer acids, such as are produced from tall oil fatty acids, oleic acid, linoleic acid, or the like. Products of this type are currently available from various commercial sources, such as, for example, the dimer and trimer acids sold under the HYSTRENE trademark by the Humko Chemical Division of Witco Chemical Corporation and under the
EMPOL trademark by Emery Chemicals. Another useful type of corrosion inhibitor for use in the practice of this invention are the alkenyl succinic acid and alkenyl succinic anhydride corrosion inhibitors such as, for example, tetrapro-penylsuccinic acid, tetrapropenylsuccinic anhydride, tetrade-cenylsuccinic acid, tetradecenylsuccinic anhydride, hexadecenyl-succinic acid, and hexadecenylsuccinic anhydride.Also useful are the half esters of alkenyl succinic acids having 8 to 24 carbon atoms in the alkenyl group with alcohols such as the polyglycols. Other suitable corrosion inhibitors include ether amines; acid phosphates; amines; polyethoxylated compounds such as ethoxylated amines, ethoxylated phenols, and ethoxylated alcohols; imidazolines; and aminosuccinic acids or derivatives thereof.
Stabilizers which may be used with the method and compositions of this invention include pyrimidine, hexahydrotriazine compounds and derivatives thereof.
Other primary, secondary and tertiary amine compounds may also be used as stabilizing additives such as hydrocarbyl polyoxypropylene di(polyoxyethylene) amines; the condensation product of an alkanolamine and the reaction product of a terpene and a compound selected from an a,p-unsaturated polycarboxylic acid.
Dehazers useful as additives include one or more alkoxylated alcohols, one or more alkoxylated fatty amines, and/or mixtures thereof. Other dehazer additives include organosiloxanes, and the reaction product formed by reacting a phenolformaldehyde resin with an alpha-olefin epoxide and then reacting the product with an alkylene oxide such as ethylene oxide, propylene oxide, or combinations thereof.
Other additives which may be used include the antiwear/extreme pressure agents selected from phosphorus-containing ashless dispersants, boron containing ashless dispersants and phosphorus and boron-containing ashless dispersants.
Suitable viscosity index improvers include methacrylates, acrylates, styrene copolymers, and ethylene-propylene copolymers.
Also useful with the methods and compositions of this invention are friction modifiers such as aliphatic amines, or ethoxylated aliphatic gamines, aliphatic fatty acid amines, aliphatic carboxylic acids, aliphatic carboxylic esters, aliphatic carboxylic ester-amides, aliphatic phosphonates, aliphatic phosphates, aliphatic thiophosphonates, and aliphatic thiophosphates.
Additive indicators useful in the practice of this invention include a wide variety of solids and liquids which are essentially innocuous in their effect on the properties of the hydrocarbonaceous fluid containing an additive and the additive indicator, and which can readily be detected by the method disclosed herein. For example, if the hydrocarbonaceous fluid is a lubricant composition which is essentially devoid of metal-containing additive components, then the additive indicator used should also be essentially devoid of metal-containing components. By "essentially devoid" is meant that the lubricant composition contains, on a weight basis, no more than 100 parts per million of such metalcontaining components.
It is a key feature of the method and compositions of this invention that the amount of additive indicator be less than the amount necessary to discolor the hydrocarbonaceous fluid to which it is added. It is to be understood however, that such amount of additive indicator may in fact discolor the additive concentrate which may be preformulated to add to the hydrocarbonaceous fluids. However, when properly admixed with a hydrocarbonaceous fluid, it is most preferable that the additive concentrate containing the additive indicator not discolor the additized fluid.In order to determine if a hydrocarbonaceous fluid is discolored by an additive indicator used in accordance with this invention, a sample of unadditized fluid should be compared to a sample of additized fluid containing the additive indicator in ordinary light, e.g., sunlight, or room light, and there should be no noticeable difference in the coloration of each sample when viewed with the unaided eye.
Accordingly, the amount of additive indicator in the method and compositions of this invention is preferably less than 6 ppm based on the total weight of hydrocarbonaceous fluid, additive, and additive indicator composition.
A particularly preferred amount of additive indicator is 4 ppm or less based on the total weight of hydrocarbonaceous fluid, additive, and additive indicator composition. When added to an additive concentrate, the amount of additive indicator is typically less than 0.4 wt. percent based on the total weight of additive concentrate. Preferably, the amount of additive indicator in the concentrate is from 0.01 to 0.25 weight percent of the total weight of additive concentrate.
In another particularly preferred embodiment of this invention, the additive indicator is a liquid dye. The dye may be one or a mixture of dyes which are typically used for the coloration of hydrocarbonaceous fluids. Hence, the dye should be compatible with the fuel or lubricant to which it is added; i.e., should be miscible with the fuel or lubricant at least at a concentration which is below the concentration which discolors the fuel or lubricant. Suitable dyes include Blue
Whitener dye #7222, Automate Red #7111, and Fluorescent Yellow #7933, all of which are commercially available from Morton Thiokol, Inc.; and Mortrace SB (90-9397), commercially available from Morton International Specialty Co.
Particularly preferred is Blue Whitener dye #7222.
The additive indicator may be admixed with the hydrocarbonaceous fluid and additive in any order, or may be admixed with the additive -- which additive and additive indicator are then admixed with a hydrocarbonaceous fluid.
Commercially available equipment and well known blending techniques can be used to perform the blending of the fluid, additive, and indicator components.
To determine the presence of the additive indicator, and thus the presence of an additive in a hydrocarbonaceous fluid composition, the hydrocarbonaceous fluid may be analyzed using the following technique. If the hydrocarbonaceous fluid is a fuel containing the additive composition and an additive indicator, a quantity of the fuel is fed to a silicon absorption column. After removing substantially all of the fuel by vacuum, air or otherwise, and drying the column, the column is visually checked for discoloration of the silicon absorber.
A discoloration of the silicon absorbent attributable to the additive indicator indicates the presence of a fuel additive containing the additive indicator. For lubricants containing an additive component and additive indicator, or for highly polar fuels, it may be necessary to first dilute the lubricant or fuel in a suitable non-polar solvent prior to feeding the lubricant or fuel to the silicon adsorption column. Suitable non-polar solvents for diluting the lubricant or fuel composition include xylene, toluene, benzene, pentane, hexane, heptane, and petroleum ether.
The method of this invention is particularly suited for determination of the presence of additives in fuels and lubricants in the field where access to laboratory analytical instruments is difficult. The method and compositions of this invention are illustrated by the following non-limiting example.
Example
A fuel additive mixture containing 99.75 weight percent HiTec 4403 (Ethyl Corporation's induction valve deposit control additive) and 0.25 weight Blue
Whitener Dye #7222 (Morton Thiokol, Inc.) was prepared. This additive mixture was then admixed with gasoline so as to obtain a concentration of fuel additive of 300 ptb (pounds per thousand barrels). Once formed, 100 mL of the gasoline and additive mixture was dissolved in 300 mL of hexane and the resulting solution fed to a 60 cubic centimeter Varian MEGA BOND ELUT column with a silicon bonded phase, part number 1225-6034 having a single holed stopper in the open end of the column and a 700 mL collection flask placed under the other end of the column. The silicon column was prepared by wetting the silicon with hexane prior to passing the solution through the column. When the all of the additive mixture and gasoline had been fed through the column, the column was dried with several syringe volumes of air by inserting a syringe through the rubber stopper and injecting air into the column until all of the fuel was removed. The presence of a blue to green color on the dried silicon indicated the presence of the indicator dye in the mixture. In lieu of drying the column with air, the column may be purged with 30 to 40 mL of methylene chloride into a clear glass vessel. The presence of a blue to green color liquid in the vessel indicates the presence of the additive mixture containing the indicator dye.
