Definitions
- the present invention relates to the use of nitrogen compounds quaternized in a specific manner as an additive for gasoline fuels, especially for operation of direct injection spark ignition (DISI) engines.
- DISI direct injection spark ignition
- Modern gasolines are unleaded in order to be compatible with catalytic convertors, and fuel in- jection has to be used in modern spark ignition engines, in order to achieve the required stoichi- ometric fuel/air mixtures.
- a typical fuel-injected spark ignition engine has multipoint fuel injec- tion, in which fuel from the injectors impinges directly onto inlet valves.
- An unleaded base gaso- line in such an engine tends to give rise to inlet valve deposits.
- a relatively new class of spark ignition engines is the class described as direct injection spark ignition engines, also known as gasoline direct injection engines; problems in such direct injection engines can arise with un- leaded gasoline by fouling of injector nozzles.
- Fuel additives are used among other things in order to avoid formation of deposits in the intake system and the intake valves of en- gines (keep-clean effect); on the other hand, fuel additives may be used in order to remove de- posits already formed at the valves and in the intake system (clean-up effect). Special additives have been developed to reduce or minimise inlet valve deposits and also injector nozzle fouling.
- WO 2013/070503 discloses the use of quaternary ammonium salts with a certain weight loss in thermogravimetric analysis (TGA) in fuels for direct injected gasoline engines.
- TGA thermogravimetric analysis
- WO 2014/195464 discloses quaternized reaction products of tertiary alkyl amines bearing Cs- to C 4 o-hydrocarbyl radicals, especially branched hydrocarbyl, with hydrocarbyl epoxides in combination with a free hydrocarbyl-substituted polycarboxylic acid as fuel additives in diesel or gasoline fuels for reducing deposits.
- WO 2017/9208 discloses quaternized reaction products of tertiary alkyl amines bearing Cs- to C 4 o-hydrocarbyl radicals, especially branched hydrocarbyl, with hydrocarbyl epoxides in combination with a free hydrocarbyl-substituted polycarboxylic acid as corrosion inhibitors in fuels.
- WO 2016/16641 discloses quaternary ammonium salts of ammonium salts substituted with optionally substituted alkyl, alkenyl or aryl groups having less than 8 carbon atoms with a carboxylic acid anion as counterion. Therefore, the substituents may contain up to 28 carbon atoms and are comparably hydrophobic as the ammonium ions disclosed in WO 2014/195464 or WO 2017/9208.
- Another object of the invention was to provide fuel additives which exhibit a higher electric conductivity in order to prevent electrostatic charging of fuels which may lead to ignition of fuel/oxygen-mixtures.
- the above object is achieved by providing quaternized nitrogen compounds of certain hydrocarbylamine compounds, and gasoline fuel compositions additized therewith.
- inventive additives as illustrated more particularly by the appended use examples, are surprisingly effective in their suitability as an additive for reducing or preventing injector fouling of direct injection gasoline engines without the effect of emulsifying water/fuel- mixtures.
- the compounds according to the present invention are effective in reducing and/or preventing internal valve deposits (IVD) in direct injection gasoline engines, especially Port Fuel Injection (PFI) engines.
- a gasoline fuel composition comprising, in a majority of a customary gasoline fuel, a proportion, especially an effective amount, of at least one reaction product comprising a quaternized nitrogen compound said reaction product being obtainable by reacting at least one compound of the following general formula 3
- the quaternizing agent comprises an epoxide of the general formula 4 where the R d radicals present therein are the same or different and are each H or a hydrocarbyl radical, the hydrocarbyl radical being an aliphatic or aromatic radical having at least 1 to 10 carbon atoms.
- gasoline fuel composition according to any of the preceding embodiments, wherein the quaternizing agent is selected from the group consisting of ethylene oxide, propylene oxide, 1 -butene oxide, 2-butene oxide, isobutene oxide, and styrene oxide in combination with a hydrocarbyl-substituted polycarboxylic acid.
- the quaternizing agent is selected from the group consisting of ethylene oxide, propylene oxide, 1 -butene oxide, 2-butene oxide, isobutene oxide, and styrene oxide in combination with a hydrocarbyl-substituted polycarboxylic acid.
- gasoline fuel composition selected from gasoline fuels, and alkanol-containing, preferably methanol, ethanol, propanol, or butanol-containing gasoline fuels, preferably bioethanol-containing fuels.
- a process for preparing a quaternized nitrogen compound according to embodiment 8, comprising the reaction of a compound of formula (3) with a hydrocarbyl epoxide in combination with a hydrocarbyl-substituted polycarboxylic acid.
- An additive concentrate comprising, in combination with further gasoline fuel additives, at least one quaternized nitrogen compound as defined in embodiment 8 or prepared according to embodiment 9.
- Quaternizable nitrogen groups or amino groups comprise especially primary, secondary and, in particular, tertiary amino groups.
- Hydrocarbyl should be interpreted broadly and comprises both long-chain and short-chain, straight-chain and branched hydrocarbyl radicals having 1 to 50 carbon atoms, which may optionally additionally comprise heteroatoms, for example O, N, NH, S, in the chain thereof.
- a specific group of hydrocarbyl radicals comprises both long-chain and short-chain, straight-chain or branched alkyl radicals having 1 to 1000, 3 to 500 or 4 to 400 carbon atoms.
- “Long-chain” or “high molecular weight” hydrocarbyl radicals are straight-chain or branched hydrocarbyl radicals and have 7 to 50 or 8 to 50 or 8 to 40 or 10 to 20 carbon atoms, which may optionally additionally comprise heteroatoms, for example O, N, NH, S, in the chain thereof.
- the radicals may be mono- or polyunsaturated and have one or more noncumulated, for example 1 to 5, such as 1 , 2 or 3, C-C double bonds or C-C triple bonds, especially 1 , 2 or 3 double bonds. They may be of natural or synthetic origin.
- M n number-average molecular weight
- M n number-average molecular weight
- They are more particularly formed essentially from C 2-6 , especially C 2-4 , monomer units such as ethylene, propylene, n- or isobutylene or mixtures thereof, where the different monomers may be copolymerized in random distribution or as blocks.
- Such long- chain hydrocarbyl radicals are also referred to as polyalkylene radicals or poly-C 2-6 - or poly-C 2 -4- alkylene radicals. Suitable long-chain hydrocarbyl radicals and the preparation thereof are also described, for example, in WO 2006/135881 and the literature cited therein.
- polyalkylene radicals examples include polyisobutenyl radicals derived from what are called “high-reactivity" polyisobutenes which feature a high content of terminal double bonds. Terminal double bonds are alpha-olefinic double bonds of the type
- Polymer which are also referred to collectively as vinylidene double bonds are also referred to collectively as vinylidene double bonds.
- Suitable high-reactivity polyisobutenes are, for example, polyisobutenes which have a proportion of vinylidene double bonds of greater than 70 mol%, especially greater than 80 mol% or greater than 85 mol%. Preference is given especially to polyisobutenes which have homogeneous polymer skeletons. Homogeneous polymer skeletons are possessed especially by those polyisobutenes formed from isobutene units to an extent of at least 85% by weight, preferably to an extent of at least 90% by weight and more preferably to an extent of at least 95% by weight.
- Such high-reactivity polyisobutenes preferably have a number-average molecular weight within the abovementioned range.
- the high-reactivity polyisobutenes may have a polydispersity in the range from 1.05 to 7, especially of about 1.1 to 2.5, for example of less than 1.9 or less than 1.5. Polydispersity is understood to mean the quotient of weight-average molecular weight Mw divided by the number-average molecular weight Mn.
- Glissopal® 2300 2300
- Other number-average molecular weights can be established in a manner known in principle by mixing polyisobutenes of different number- average molecular weights or by extractive enrichment of polyisobutenes of particular molecular weight ranges.
- a specific group of long-chain hydrocarbyl radicals comprises straight-chain or branched alkyl radicals ("long-chain alkyl radicals") having 8 to 50, for example 8 to 40 or 8 to 30 or 10 to 20, carbon atoms.
- a further group of specific long-chain hydrocarbyl radicals comprises polyalkylene radicals which are formed essentially from C 2 -6, especially C 2-4 , monomer units, such as ethylene, propylene, n- or isobutylene or mixtures thereof and have a degree of polymerization of 2 to 100, or 3 to 50 or 4 to 25.

- the aromatics content of the gasoline is e.g. from 10 to 50% by volume, e.g. from 30 to 42% by volume, in particular from 32 to 40% by volume or not more than 35% by volume.
- the sulfur content is e.g. of from 2 to 500 ppm by weight, e.g. of from 5 to 100 or not more than 10 ppm by weight.
- the olefin content of the gasoline can be up to 50% by volume, e.g. from 6 to 21% by volume, in particular from 7 to 18% by volume.
- the gasoline has a benzene content of not more than 5% by volume, e.g. from 0.5 to 1.0% by volume, in particular from 0.6 to 0.9% by volume.
- the gasoline has an oxygen content of not more than 30% by weight, e.g. up to 10% by weight or from 1.0 to 3.7% by weight, and in particular from 1.2 to 2.7% by weight.
- a gasoline which has an aromatics content of not more than 38% by volume or preferably not more than 35% by volume, and at the same time an olefin content of not more than 21 % by volume, a sulfur content of not more than 50 or 10 ppm by weight, a benzene content of not more than 1.0% by volume and an oxy-gen content of from 1.0 to 2.7% by weight.
- the amount of alcohols and ethers contained in the gasoline may vary over wide ranges.
- Typical maximum contents are e.g. methanol 15% by volume, ethanol 85% by volume, isopropanol 20% by volume, tert-butanol 15% by volume, isobutanol 20% by volume and ethers containing 5 or more carbon atoms in the molecule 30% by volume.
- the summer vapor pressure of the gasoline (at 37°C) is usually not more than 70kPa, in particular not more than 60kPa.
- the research octane number (RON) of the gasoline is usually from 75 to 105.
- a usual range for the corresponding motor octane number (MON) is from 65 to 95.
- Preparation examples 1 to 4 Quaternization of tertiary amines with propylene oxide in the presence of hydrocarbyl-substituted succinic acids
- R 1 here represents long-chain hydrocarbyl
- R 2 , R 3 and R 4 correspond to R a , R b and R c as defined above
- R 5 corresponds to R d as defined above
- R is H or a radical obtained by esterification with the epoxide, for example -CH CH(R )OH
- Reagents used Polyisobutylene succinic anhydride (PIBSA, Glissopal® SA (BASF)):
- a 2 I autoclave was filled with a solution of the respective amine and polyisobutylene succinic acid in 2-ethylhexanol.
- the autoclave was flushed with nitrogen, the solution was heated to 50°C and a pressure of 2 bar was adjusted with nitrogen.
- Propylene oxide was added within 30 minutes.
- the reaction mixture was stirred at 50°C for 20 h.
- the reaction mixture was cooled to 25°C and the autoclave was flushed with nitrogen to obtain the product solution.
- the solution was transferred to a 2 I double-walled reactor. Unreacted propylene oxide was removed by ni- trogen purging (10 l/h) at 50°C under vacuum (70 mbar) for 6 h.
- Comparative Example 1 Inventive example 6 from WO 2014/195464. The degree of quaternization was determined to be 96%. C. Use examples:
- the additives are used either as a pure substance (as synthesized in the above preparation examples) or in the form of an additive package.
- Nozzle coking is measured as change of activation time of the injector (tij), which is measured periodically within the test procedure. Due to nozzle coking, the hole diameters of the injector holes are reduced, and the activation time adjusted by the Engine Control Unit (ECU) accord- ingly. The activation time in milliseconds is a direct readout from the ECU via ECU control soft- ware. A prolongation of activation time is an indicator for nozzle coking. The test duration was 48 h.
- dirty-up is achieved by running the engine over 48 hours as described for the keep-clean procedure (see above) with base fuel.
- the relative change of acti- vation time is determined as described above for the keep-clean test.
- the subsequent clean-up run is done with additized base fuel over 10 h.
- At the end of the test 3 data points are deter- mined within 15 minutes, which mean value gives the activation time at end of clean-up test.
- test result for the clean-up is the relative change of activation time of the injectors relative to the average activation time determined at the end of the dirty-up phase.
- results are summa- rized in table 2.
- test results show that PI BA alone is not capable of completely removing the deposits formed during the dirty-up at a dosage of 300 mg/kg (tests No. 1 and 2).
- results further show that both comparative example 1 and inventive example 4 at dosages of 30 mg/kg (15 mg/kg active) as top-up to 300 mg/kg Kerocom PIBA are capable of completely removing the deposits formed during the dirty-up (tests No. 3-6).
- Interface Table 3a Demulsification behavior according to ASTM D1094-07.
- test results show that fuel additive package 2 containing inventive example 4 shows a slightly improvedlevel of corrosion protection performance in water, respectively a comparable corrosion protection performance in synthetic sea water compared to fuel additive package 1 containing comparable example 1 at the same dosage.
