Definitions
- the invention is in the field of fragrances and relates to a new process for the production of fatty aldehydes.
- Lower aldehydes such as 1-octanal or 1-decanal, are renowned raw materials for the fragrance industry.
- Their production based on fatty alcohols is known from the prior art, for example by oxidation with hypochlorite in the presence of 4-ethoxy-2,2,6,6 -tetramethylpiperidin-l-yloxyl ("Tempo") is known.
- the air oxidation of the alcohols can take place in the presence of ruthenium or platinum catalysts.
- unsaturated alcohols can be isomerized to aldehydes under the influence of one-pentacarbonyl.
- the fatty acids are obtained from fatty acids Aldehydes by hydrogenation on oxidic copper catalysts of the Adkins type or by reaction with peracids in the presence of titanium (IV) oxide
- oxidic copper catalysts of the Adkins type or by reaction with peracids in the presence of titanium (IV) oxide
- EP 0320074 AI Engelhard proposes copper catalysts doped with iron for the same purpose
- Rosenmund reaction in which acid chlorides are hydrogenated on Lindlar catalysts to the corresponding aldehydes.
- the known processes have the disadvantage that they are technically complex, produce low yields and / or are characterized by unsatisfactory selectivities. Accordingly, the object of the present invention was to provide a new method which reliably avoids the disadvantages of the prior art mentioned. Description of the invention
- the invention relates to a process for the preparation of aldehydes, in which fatty alcohols are continuously dehydrogenated in the presence of oxidic copper / zinc catalysts at temperatures in the range from 200 to 280 ° C. and pressures in the range from 10 mbar to 1 bar.
- Suitable starting materials for the process according to the invention are linear or branched, saturated or unsaturated primary alcohols, which for the sake of simplicity are summarized under the name fatty alcohols and preferably follow the formula (I) in which
- R 1 represents a linear or branched saturated or unsaturated alkyl and / or alkenyl radical having 6 to 22, preferably 8 to 12 and in particular 8 to 10 carbon atoms.
- Typical examples are caproic alcohol, caprylic alcohol, 2-ethylhexyl alcohol, Caprinalko- alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl rylalkohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl, ünolylalkohol, linolenyl alcohol, elaeostearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, Eru - Cyl alcohol and brassidyl alcohol and their technical mixtures, which are obtained, for example, in the high-pressure hydrogenation of technical methyl esters based on fats and oils or aldeh
- the fatty aldehydes are preferably produced in a shaft reactor with a fixed catalyst bed.
- the oxidic copper / zinc catalysts are commercial Adkins contacts, ie solids with a spinel structure, which preferably contain chromium, cadmium, cerium, barium, silicon and / or aluminum as further metal components. Basic copper / zinc / aluminum oxides are particularly preferred.
- the reaction usually takes place at temperatures in the range from 200 to 280, preferably 240 to 260 ° C.
- the dehydrogenation is carried out either without pressure or at a reduced pressure in the range of preferably 20 to 40 mbar.
- the liquid hour space velocity (LHSV) can be in the range from 1 to 3, preferably 1.1 to 2.6 h "1.
- the yield of fatty aldehydes is in the range of at least 60 and preferably 65 to 70% of theory, while the selectivity is at least 90 and preferably 95 to 98% It is advisable to carry out the dehydrogenation in the presence of nitrogen as the carrier gas.
