Definitions
- the invention is in the field of oleochemical raw materials and relates to a new industrial process for curing unsaturated compounds.
- Oleochemical raw materials from the natural fats and oils to the first finishing products, the fatty acids, fatty acid esters and fatty alcohols, are mixtures of unsaturated and saturated homologues, the degree of unsaturation essentially being due to the raw material used and the so-called iodine number is expressed.
- synthetic substances that are obtained by fermentation of suitable paraffins are also currently gaining a role.
- Long-chain dicarboxylic acids which are produced by biooxidation of paraffins or monocarboxylic acids in the presence of Candida tropicalis may be mentioned [cf. EP 0229252 AI (Henkel)].
- the object of the present invention was to provide an improved process for hardening unsaturated fatty substances, especially unsaturated carboxylic acids and in particular unsaturated dicarboxylic acids, with the aid of which iodine numbers are below 2, preferably below 1 and in particular below 0 , 5 can be achieved, the reaction speed being simultaneously increased significantly compared to the known prior art.
- the invention relates to a process for curing unsaturated fatty substances in the presence of transition metal catalysts, which is characterized in that the double bonds are saturated at pressures in the range from 100 to 300, preferably 150 to 280 and in particular 200 to 250 bar.
- unsaturated fatty substances that serve as starting materials for hardening is not critical in itself.
- Unsaturated carboxylic acids, unsaturated carboxylic acid alkyl esters and unsaturated carboxylic acid polyol esters are typically suitable for this purpose.
- the unsaturated carboxylic acids preferably follow the formula (I)
- a 1 represents a mono- or polyunsaturated, linear or branched hydrocarbon radical having 5 to 21 carbon atoms and R 1 represents hydrogen or a carboxyl group, ie it can be both mono- and dicarboxylic acids, the latter in this respect are preferred when the effect of increasing the reaction rate is most clearly shown there.
- suitable monocarboxylic acids are the fatty acids having 6 to 22 and preferably 16 to 22 carbon atoms, such as palmoleic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, gadolinic acid and behenic acid and their technical mixtures.
- branched unsaturated fatty acids which are obtained as a monomer fraction in the dimerization of unsaturated monocarboxylic acids, especially oleic acid.
- Suitable dicarboxylic acids are those which have 3 to 22 carbon atoms, such as maleic acid and fumaric acid, and in particular those unsaturated dicarboxylic acids which are obtained by enzymatic carboxylation of the corresponding paraffins.
- the unsaturated C 8 -dicarboxylic acid should be mentioned here in particular.
- Such branched, optionally naphthenic di- and tricarboxylic acids can also be used as starting materials which are obtained in the oligomerization of unsaturated monocarboxylic acids and are usually referred to as dimer or trimer fatty acids.
- carboxylic acids their alkyl esters can also be used.
- the unsaturated carboxylic acid alkyl esters preferably follow the formula (II)
- these are the ethyl, propyl, butyl, caprylic and preferably methyl esters of the abovementioned mono- and dicarboxylic acids.
- the polyol esters, especially the glycerol esters can also be used instead of the alkyl esters.
- Unsaturated carboxylic acid polyol esters are preferably unsaturated mono-, di- and / or triglycerides, which are usually natural oils with more or less high levels of unsaturated homologues in the mixture.
- Typical examples are palm oil, palm kernel oil, coconut oil and beef tallow and preferably olive oil, sunflower oil, rapeseed oil, linseed oil, rice husk oil and the like.
- Typical for the unsaturated fatty substances used is an iodine number in the range from 10 to 300, preferably 50 to 200 and in particular 70 to 125, which is reduced to values below 2, preferably below 1 and in particular below 0.5.
- the unsaturated fatty substances can be present in a mixture with their saturated homologs, as long as the iodine number of the mixture is at least 10.
- transition metals are suitable as hardening catalysts, among which nickel and in particular palladium are particularly preferred. These metals are preferably present on supports, silicon dioxide and, in particular, activated carbon being particularly suitable for this purpose.
- Pd / activated carbon catalysts as described, for example, in EP 0632747 B1 (Henkel), has proven to be particularly advantageous. With regard to the production and use of such catalysts, reference is made in full to the content of this document.
- the unsaturated fatty substances can be hardened in a manner known per se, for example by arranging the catalyst in a fixed bed and bringing the reactant and hydrogen into contact with one another in a cocurrent or countercurrent process.
- the temperatures for curing are usually in the range from 150 or 220 and preferably 180 or 200 ° C.
- the process can of course also be carried out discontinuously, a continuous procedure is preferred, since in this way a sealed hydrogen cycle gas can be worked and the separate expansion and compression is eliminated.
