Definitions
- the present invention relates to novel processes for the preparation of stabilized oil formulations by means of certain carbodiimides.
- a range of base oils and lubricant base substances e.g. Triglycerides, synthetic carboxylic acid esters, phosphoric acid triesters, olefin-dicarboxylic acid copolymers and silicone oils are attacked by water or oxidants to form acidic cleavage products and alcohols.
- These acidic fission products are a measure of the degree of decomposition. They can be given quantitatively in the form of the acid number, so that this serves as a measure of the aging state of the lubricating oils.
- the presence of acids or acidic cleavage products accelerates the hydrolysis autocatalytically. Since water is always present in small quantities under technical conditions, the useful life of lubricants is accordingly limited.
- the object of the present invention was therefore to provide methods which do not have the disadvantages of the prior art.
- the present invention thus provides a novel process for the preparation of oil formulations, according to which at least one carbodiimide of the formula (I) With
- the carbodiimides of formula (I) are commercial compounds which are e.g. can be obtained from Rhein Chemie Rheinau GmbH under the trade name Stabaxol® or Additin®.
- the oil according to the invention is preferably mineral oils, more preferably naphthenic low sulfur base oils and / or natural fats, oils or waxes, triglycerides preferably soybean oil, rapeseed or sunflower oil and also artificially produced esters e.g. starting from methanol, 2-ethylhexanol, glycol, glycerol, trimethylpropanol (TMP), pentaerythritol, neopentylglycol esterified with e.g. Stearic acid, oleic acid, adipic acid, terephthalic acid and trimellitic acid.
- mineral oils more preferably naphthenic low sulfur base oils and / or natural fats, oils or waxes, triglycerides preferably soybean oil, rapeseed or sunflower oil and also artificially produced esters e.g. starting from methanol, 2-ethylhexanol, glycol, glycerol, trimethylpropanol
- the oil is a trimethylolpropane ester (TMP) of the general formula (II)
- radicals R 3 , R 4 and R 5 each of which may be the same or different, have a linear or branched alkyl group having 5 to 22 carbon atoms.
- the radicals R 3 , R 4 and R 5 which may each be identical or different, define a linear or branched alkyl group having 7 to 18 carbon atoms.
- TMP oleate Trimethylolpropane trioleate
- the artificially produced esters based on methanol are preferably rapeseed oil methyl ester.
- the oil formulations stabilized by the process according to the invention may furthermore comprise further additives customary for this field of application.
- they may be antioxidants or metal deactivators.
- the oil formulation therefore additionally contains 0.005 to 1.0% by weight of an antioxidant and / or 0.01 to 2.0% by weight of a metal deactivator, in each case based on the oil formulation.
- the preferred amount of antioxidant is between 0.1 and 0.5% by weight, and more preferably 0.1-0.2% by weight, based on the oil formulation.
- the preferred amount of metal deactivator is between 0.1 and 1, 0 wt .-% and in particular 0.1 to 0.2 wt .-%, based on the oil formulation.
- the antioxidants are preferably selected from the group consisting of bishydroxytoluene, hydroquinone, 4-tert-butylcatechol, naphthol, phenylnaphthylamines, diphenylamines, phenolic thioethers, tocopherols and mixtures of the listed substances.
- the metal deactivator is preferably selected from the group consisting of organic heteroatom compounds, more preferably triazoles, toluyltriazoles, Dimercaptothiadiazolen and mixtures of the listed substances.
- concentrations of 0.05-2% by weight of carbodiimide preferably 0.1-1% by weight and more preferably 0.2-0.5% by weight, based on the oil formulation, are used .
- the addition of the carbodiimide preferably takes place in a mixing or storage container, particularly preferably directly in the container, preferably in a drum or container.
- the carbodiimide is poured into the oil or pumped in via a line.
- this can be additionally reinforced by stirrers, such as blade, coil or anchor agitator, dispersants, drum or container stirrers.
- the carbodiimide in the mixing or storage container more preferably directly in the container, preferably presented in a barrel or container, and then poured the oil.
- pouring the oil usually enters a sufficient mixing.
- Another object of the invention are also Olformulierungen prepared by the novel process and their use as process oils, propellants, heat transfer oils, engine oils, greases, metalworking fluids, turbine and transformer oils.
- the following examples serve to illustrate the invention without being limiting.
- SXL I Stabaxol ® I, a solid monomeric carbodiimide based on 2,6-diisopropyl Rhein Chemie Rheinau GmbH phenyl isocyanate.
- TMP-oleate Synative ® ES TMP 05 from BASF SE.
- RME Rapeseed oil methyl ester
- the toast test ASTM D 2619 (“Beverage bottle test”) is part of internationally recognized oil formulation specifications and is used to test the hydrolytic resistance of liquids and tracks the acid number increase as a measure of the hydrolytic stability of the oil.
- test oil rapeseed oil methyl ester
- Table 1 show that the hydrolytic stability of the oil formulations prepared by the process according to the invention is already given when using low carbodiimide concentrations.
- the temperature must be raised to 80 ° C. in order to be able to produce any solution at all, which is complicated and involves undesired decomposition processes with liberation of toxic substances.
- Table 2 decrease in the acid value at 30 ° C: comparison between Stabaxol ® MTC (ERF) and SXL I (V) Experimental procedure:
