Definitions
- the invention is in the field of cosmetic oil bodies and relates to an improved process for the production of, for example, Guerbet alcohols and dialkylcyclohexanes, which does not require heavy metal catalysts in the condensation and is distinguished by a higher reaction rate with improved selectivity.
- Guerbet alcohols are primary alcohols branched in the 2-position, which are obtained by condensation of linear fatty alcohols.
- the products are mainly used as oil components for the production of cosmetic emulsions. They are generally prepared from fatty alcohols which initially condense under the influence of strong bases and heavy metal compounds such as copper or zinc oxide. It is believed that under the reaction conditions the alcohol is first dehydrated to the aldehyde, this undergoes aldol condensation with itself and the condensation product is then hydrogenated to the alcohol. An overview of this can be found, for example, in Angew.Chem. 64: 212 (1952). Dialkylcyclohexanes are prepared in a similar manner by double condensation of fatty alcohols with cyclohexanol in the presence of heavy metals.
- the invention relates to a process for the preparation of branched alcohols and / or hydrocarbons, in which carbonyl compounds are condensed in the presence of acids or bases and the resulting ⁇ , ⁇ -unsaturated condensation products are then hydrogenated.
- Aldehydes, ketones and mixtures thereof are primarily suitable as carbonyl compounds.
- Suitable aldehydes are, for example, fatty aldehydes which preferably follow the formula (I)
- R 1 represents a linear or branched alkyl radical having 6 to 12 and in particular 8 to 10 carbon atoms.
- Typical examples are hexanol, octanol, 2-ethylhexanal, decanol, dodecanol and mixtures thereof.
- fatty ketones preferably those that follow the formula (II)
- R 2 and R 3 independently of one another represent linear or branched alkyl radicals having 6 to 12 carbon atoms.
- Typical examples are dihexyl ketone, dioctyl ketone, di-2-ethylhexyl ketone, didecyl ketone or didodecyl ketone.
- cyclic ketones can also be used, preferably cyclohexanone.
- the condensation reaction can be carried out in a manner known per se, i.e. the carbonyl compounds are initially introduced together with the acids or bases and heated to temperatures in the range from 20 to 250, preferably 200 to 240 ° C.
- the reaction can be carried out without pressure or at pressures up to 30, preferably up to 5 bar.
- Alkali bases such as e.g. Alkali hydroxides or alkali carbonates.
- the amount of catalysts can be 1 to 10, preferably 3 to 5 mol%, based on the carbonyl compounds. To shift the reaction equilibrium to the product side, it is always advisable to distill off the condensation water continuously.
- the hydrogenation of the unsaturated aldehydes or ketones obtained as an intermediate can be carried out using conventional hydrogenation catalysts, preferably based on nickel, copper and / or zinc.
- the hydrogenation is usually carried out at temperatures in the range from 20 to 350, preferably 50 to 250 ° C. and pressures in the range from 1 to 300, preferably 20 to 250 bar.
- the reaction products can then be purified by distillation.
- Example 1 In a stirring apparatus consisting of flask, heating element, water separator, reflux condenser and nitrogen transfer, 1 g (0.015 mol) of potassium hydroxide was added to 500 g (3.2 mol) of decanal (99% by weight) at 20 ° C. and applied Heated 210 ° C. The water obtained in the reaction was continuously distilled off. After 3 h the reaction was complete, the reaction mixture was cooled to 20 ° C. and the potassium hydroxide which had precipitated out was filtered off. The resulting clear liquid contained 90% by weight of ⁇ , ⁇ -unsaturated aldehyde, 4% by weight of trimers, 2% by weight of ester and 4% by weight of unreacted starting aldehyde.
- the reaction mixture was transferred to an autoclave and hydrogenated in the presence of a nickel catalyst at 230 ° C. and 250 bar within 3 hours until no more hydrogen uptake could be seen.
- the hydrogenation product consisted of 90% by weight of 2-octyldodecanol, 6% by weight of decanol and 4% by weight of trimers. After distillation, the 2-octyldodecanol was obtained in a purity of 95.7% by weight.
- Example 2 Analogously to Example 1, 500 g (3.9 mol) of octanal were condensed in the presence of 1.2 g (0.02 mol) of potassium hydroxide. The resulting product contained 88% by weight of ⁇ , ⁇ -unsaturated aldehyde, 6% by weight of trimers, 2% by weight of ester and 4% by weight of unreacted octanal. After hydrogenation, a mixture of 88% by weight of 2-hexyldecanol, 6% by weight of octanol and 6% by weight of trimers was obtained. After distillation, the 2-hexyldecanol was obtained in a purity of 93.6% by weight.
- Example 3 Analogously to Example 1, 650 g (5.0 mol) of 2-ethylhexanal and 245 g (2.5 mol) of cydohexanone were condensed with the addition of 40 g of 45% strength by weight aqueous potassium hydroxide solution. After 2 h the reaction temperature of 240 ° C was reached, the end point being indicated by the completion of the water separation. The product was washed neutral with hot water and dried with sodium sulfate.
- the GC analysis gave a composition of 85.4% by weight of 2,6-di (2-ethylhexyl) cyclohexane , 8.2% by weight of 2 (2-ethylhexyl) cyclohexane, 1.3% by weight of 2-ethylhexane, 0.3% by weight of cyclohexane and 4.8% by weight of oligomers.
- the unreacted starting materials were removed by distillation.
