Definitions
- the present invention relates to a new process for the preparation of the tautomeric form I of 2,4,6-trianilino-p- (carbo-2'-ethylhexyl-1'-oxy) -1,3,5-triazine
- the invention also relates to the use of the form I isolated in this way as a light stabilizer in cosmetic preparations.
- EP-B 087 098 (1) describes the preparation of 2,4,6-trianilino-p- (carbo-2'-ethylhexyl-1'-oxy) -1,3,5-triazine from cyanuric chloride. rid and p-aminobenzoic acid-2-ethylhexyl ester and the purification of the crude product by recrystallization from gasoline.
- DE-A 35 18 670 (2) relates to the use of esters from a branched alkanoic acid with 6 to 10 C atoms and a saturated aliphatic alcohol with 10 to 20 C atoms as solvents in the preparation of s-triazine derivatives such as 2, 4, 6-trianilino-p- (carbo-2 'ethylhexyl-1' oxy) -1,3,5-triazine.
- the products obtained in the abovementioned processes are generally mixtures of tautomers, as can easily be derived from associated IR spectra. It is known for example from J. Elguero, C. arzin, AR Katritzky and P. Linda, Advances in Heterocyclic Chemistry, Supplement 1, The Tautomerism of Heterocycles, Academic Press New York, 1976, Kp. 2, p. 168, that with amino-s-triazine derivatives, tautomers with regard to the NH protons can generally occur.
- the substance is chemically uniform when tested for its suitability for use and when used.
- Mixtures of substances with different physical properties, including tautomeric mixtures, cannot be used, especially for toxicological tests and compatibility tests, the results of which are of particular relevance for the ingredients of cosmetic preparations, because feeding tests with living organisms in these test organisms cannot be assumed to have a constant composition , so that the result of these tests could be falsified.
- such mixtures are often subject to strong fluctuations in the composition due to slight changes in the production conditions, so that a particular composition is difficult to reproduce.
- the present invention was therefore based on the object to remedy the disadvantages described when using 2, 4, 6-trianilino-p- (carbo-2 'ethylhexyl-l'-oxy) -1,3, 5-triazine.
- Both straight-chain, branched and cyclic alcohols are suitable as aliphatic alcohols with 2 to 8 carbon atoms.
- Examples include ethanol, n-propanol, iso-propanol, n-butanol, tert. -Butanol, n-pentanol, n-hexanol, n-octanol, 2-ethylhexanol and cyclohexanol.
- a preferred alcohol used as solvent is ethanol.
- Suitable aliphatic carboxylic acid alkyl esters with a total of 3 to 10 carbon atoms are, for example, straight-chain carboxylic acid esters such as ethyl formate, n-propyl formate, n-propyl acetate, methyl acetate, ethyl acetate, n-propyl acetate, n-butyl acetate, butyl acetate, butyl ester, propyl ester and n-butyl butyrate.
- Aliphatic carboxylic acid alkyl esters with a total of 3 to 6 carbon atoms are preferred, particularly preferably ethyl acetate.
- Aromatic carboxylic acid alkyl esters with a total of 8 to 12 carbon atoms are understood to mean, for example, methyl benzoate, ethyl benzoate, n-propyl benzoate, iso-propyl benzoate, n-butyl benzoate, tert-butyl benzoate, preferably methyl benzoate ,
- Aliphatic carbonic acid esters with a total of 3 to 9 carbon atoms include dimethyl carbonate, diethyl carbonate, di-n-propyl carbonate, di-iso-propyl carbonate, di-n-butyl carbonate and propylene carbonate, preferably dimethyl carbonate.
- Suitable carboxylic acid nitriles having a total of 2 to 8 carbon atoms are, for example, acetonitrile, propiononitrile, n-butyronitrile, benzonitrile, preferably acetonitrile.
- Dialkyl ketones with a total of 3 to 6 carbon atoms include straight-chain, branched and cyclic dialkyl ketones, for example acetone, butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and cyclohexanone, preferably acetone.
- aliphatic sulfones with a total of 3 to 6 carbon atoms
- tetramethylene sulfone As a representative of aliphatic sulfones with a total of 3 to 6 carbon atoms, for example, tetramethylene sulfone.
- the hydrocarbons optionally used as cosolvents can be both aliphatic hydrocarbons such as pentane, hexane, petroleum ether, ligroin or cyclohexane and / or aromatic hydrocarbons such as toluene or xylene. These hydrocarbons can be contained in an amount of up to 30% by weight, preferably in an amount of not more than 10% by weight.
- a preferred embodiment of the ⁇ method of the invention is characterized in that one carries out the crystallization in one of the above-mentioned aliphatic alcohols having 2 to 4 carbon atoms, in one of the above-mentioned aliphatic carboxylic alkyl esters having a total of 3 to 6 carbon atoms or a mixture thereof ,
- the crystallization is particularly preferably carried out in ethanol, ethyl acetate or a mixture thereof as a solvent.
- the solvents used in the context of the present invention can be both anhydrous and have a water content of at most 10% by weight, preferably at most 5% by weight, particularly preferably at most 2% by weight. This applies in particular to the aliphatic alcohols mentioned above and to the aliphatic alkyl carboxylates.
- the recrystallization is usually carried out by dissolving the tautomer mixture in the solvent or the solvent mixture at temperatures of 40 to 120 ° C, preferably 60 to
- the amount of solvent is advantageously 100 to 2000 wt .-%, preferably 150 to 600 wt .-%, based on the tautomer mixture.
- the tauto is at temperatures of about 15 to 40 ° C
- the tautomer mixture used is advantageously mixed directly with the solvent or solvent mixture mentioned as a melt.
- the tautomer mixture can also be introduced in crystallized form into the hot solvent or heated together with it.
- the tautomeric form I is stable as such and does not convert back into the tautomer mixture in solid or in dissolved form. 5
- the present invention also relates to the use of the tautomeric form I isolated in this way as a light stabilizer in cosmetic preparations.
- cosmetic preparations such as light protection emulsions, oil-in-water light protection creams, water-in-oil light protection creams or light protection foams can be found in patent specification (1).
- Another advantage of the process according to the invention is the good crystallizability and, associated with this, the good filterability and the good drying behavior of the tautomerically pure product.
- the IR spectrum of the product showed only one band for the carboxyl groups at 1697 cm-1 (see FIG. 1) in the region of the carbonyl stretching vibrations, in contrast to the corresponding double band of the product from comparative example A.
- Example 2 Analogously to Example 1, the recrystallization was carried out using 400% by weight of ethyl acetate, based on the tautomer mixture used. The tautomerically pure product was obtained in a yield of 58%.
- Example 2 Analogous to Example 1, the recrystallization was carried out in each case with ethylhexanol (Ex. 3), cyclohexanol (Ex. 4), methyl benzoate (Ex. 5), tetramethylene sulfone (Ex. 6), dimethyl carbonate. (Ex. 7), methyl ethyl ketone (Ex. 8), acetonitrile (Ex. 9) and acetone (Ex. 10) as well as with solvent mixtures of 90% by weight ethanol / 10% by weight xylene (Example 11) and 90% by weight .-% Ethyllacetate / 10 wt .-% xylene (Example 12) carried out.
- solvent mixtures 90% by weight ethanol / 10% by weight xylene (Example 11) and 90% by weight .-% Ethyllacetate / 10 wt .-% xylene (Example 12) carried out.
- the IR spectra of the isolated products also showed only one band for the carboxyl groups at 1697 cm-1 in the area of the carbonyl stretching vibrations.
- the tautomer mixture obtained in the production was recrystallized from gasoline with a boiling point of 120 to 130 ° C.
- the tautomerically pure compound I was dissolved in Cs-Cio-coconut fatty acid triglyceride (solubility 5.8 g per 100 g oil) and 2-ethylhexanoic acid cetylstearyl ester (solubility 1.0 g per 100 g oil). Both solutions were still clear after 2 days.
