Definitions
- Tricyclohexylidene peroxide (trimeric, cyclic cyclohexanone peroxide) in particular is a popular compound for the synthesis of cyclopentadecane and hexadecanolide - starting materials for musk fragrances.
- nitric acid was expressly discouraged because of the feared formation of unstable persitric acid.
- the object of the invention is therefore to create a method which has the stated advantages.
- this is achieved by a process for the preparation of trimeric ketone peroxides by reacting cyclic or open-chain ketones with H 2 O 2 in the presence of an acid catalyst in one suitable solvent, which is characterized in that nitric acid is used as catalyst.
- Cyclic ketones with 5 to 12 chain links are used.
- the cyclic ketones can be substituted with one or more alkyl groups with 1 to 6 carbon atoms.
- the open-chain ketones in question have the formula R 1 -CO-R 2 , in which R 1 and R 2 can each independently contain 1 to 15 carbon atoms in the chain, so that R 1 + R 2 have a maximum value of 30, can have a minimum value of 2.
- the chains can in turn be substituted with alkyl groups of 1 to 6 carbon atoms. Cyclohexanone and cyclohexanone substituted with 1, 2 or 3 alkyl groups with 1 to 6 C atoms and cyclopentanone are preferred as the cyclic ketone.
- Suitable cyclic ketones of the preferred group are 3,3,5-trimethylcyclohexanone, 2-methylcyclohexanone, 4-methylcyclohexanone and 4-tert-butylcyclohexanone. Cyclododecanone also proved to be suitable. Among the alicyclic ketones, methyl ethyl ketone and acetone are particularly preferred. Other preferred ketones are those in which R 1 or / and R 2 has 1 to 4 carbon atoms straight-chain or branched, in particular a tert-butyl group.
- the nitric acid is expediently used in a concentrated form, preferably as a 60 to 75% solution.
- the amount is expediently 0.3 to 0.7 mol, preferably 0.4 to 0.6 mol, per mol of cyclohexanone.
- Suitable solvents are liquid hydrocarbons, in particular those with 6 to about 20 carbon atoms, which can be linear or branched. Examples of suitable solvents are isododecane and the hydrocarbons sold under the trade names Shellsol T Isopar M, G and E, and aromatics such as toluene, xylene and phthalate esters.
- Diesel fuel is particularly suitable as a solvent for trimeric methyl ethyl ketone peroxide (MEKP) and trimeric acetone peroxide (AP).
- MEKP trimeric methyl ethyl ketone peroxide
- AP trimeric acetone peroxide
- the solvents mentioned have a desensitizing effect and reduce the risk of explosion of the pure peroxides.
- Solid phlegmatizing agents such as phthalates and fillers such as chalk, kaolin and silica, in particular dicyclohexyl phthalate, can also be used for the desensitization.
- isoalkanes e.g. Isopar G, proven useful.
- acetic acid is preferably used as the solubilizer in the process of the invention.
- the best results are achieved with 30 to 100 g of acetic acid per mole of ketone used.
- the amount of acetic acid preferred as solubilizer could be reduced by 80% compared to the Harding and Whalen method (from 250 g to 50 g / mol ketone). This is an important economic factor and leads to a discharge of the wastewater from organic substances.
- other substances such as propionic acid, acetonitrile, lower alcohols such as methanol, and mixtures thereof can be used as solubilizers instead of or in addition to acetic acid.
- an aliphatic hydrocarbon for example Isopar G
- the desired reaction product is in solution in the organic phase, unreacted starting products and by-products are in the aqueous phase.
- the organic solution can be used directly for further reactions or the trimeric ketone peroxide can be isolated therefrom as a solid.
- the entire reaction mixture is therefore treated with a sodium sulfite solution at the end of the reaction, with H 2 O 2 and all hydroperoxides being reduced. After the phase separation, no further reaction can occur.
- the hydrogen peroxide is expediently used in concentrated commercial form, ie as an approximately 60 to 80% aqueous solution.
- concentrated commercial form ie as an approximately 60 to 80% aqueous solution.
- 70% H 2 O 2 is suitable.
- the reaction temperature is kept in the range of 10 to 25 ° C, preferably in the range of 15 to 20 ° C. In this preferred temperature range, the reaction proceeds completely in 1 to 3 hours.
- the process according to the invention can also be carried out continuously with very good results. It is advisable to use several for continuous operation reaction vessels or containers connected in series.
- the reaction time required for the completion of the reaction which, as mentioned above, is 1 to 3 hours, preferably 1.5 to 2 hours, is achieved in the continuous mode of operation by appropriately matching the number and size of the different reaction vessels to the flow rate.
- An example of the continuous implementation of the process according to the invention using six reaction vessels is shown in Figure 1 of the accompanying drawings. The number of reaction vessels, their size and the residence times can of course be changed and adapted to the given conditions, as is readily apparent to the person skilled in the art.
- solutions of the trimeric ketone peroxides obtained according to the invention or the solid products obtained therefrom are particularly suitable for the polymerization of monomers, for the hot curing of unsaturated polyester resins, for the degradation of polypropylene (PP), as diesel additives for improving the cetane number and reducing the soot formation (in particular trimeric MEKP and AP).
- PP polypropylene
- the corresponding dimeric ketone peroxides can be obtained from the solutions obtained according to the invention by heating the organic solution above 25 to 50 ° C.
- Dimeric cyclohexanone peroxide can be used to produce caprolactam or anti-malaria drugs.
- Example 1 Batch Process for the Preparation of a Trimeric Cyclohexanone Peroxide (CHP) Solution 300 g (3.06 mol) of cyclohexanone, 150 g of acetic acid and 1000 g of Isopar G (an isoalkane) are placed in a 2 l reactor and the mixture is cooled to + 15 ° C. With stirring and cooling, 150 g (3.09 mol) of 70% H 2 O 2 are added over the course of about 15 minutes, the temperature being kept below + 20 ° C. 135 g / 1.39 mol) of 65% nitric acid are then added in 25-30 minutes with good cooling. The mixture is stirred at 15-1.8 ° C.
- CHP Trimeric Cyclohexanone Peroxide
- the organic phase is washed with 500 ml of 8% sodium hydroxide solution and twice with 500 ml of water.
- cyclohexanone, hydrogen peroxide, nitric acid, acetic acid and Isopar G are simultaneously conveyed into reactor 1, where they are kept at 15 ° C. with stirring and cooling.
- the trimeric CHP mainly forms under the catalytic influence of nitric acid.
- the subsequent reactors 2, 3, 4 with the same reaction temperature are used for the after-reaction.
- the corresponding dimeric cyclohexanone peroxide and open-chain hydroperoxide-containing CHP are formed as a by-product.
- the disruptive hydroperoxide groups are reduced in the reactor 5 with sodium sulfite.
- the acid still present in the reaction solution is neutralized in the reactor 6 with sodium hydroxide solution and removed with the aqueous phase by separation with a separator.
- nitric acid, Isopar G, acetic acid and hydrogen peroxide are brought together with the cyclohexanone at the same time, the reaction mixture is reduced and neutralized without removing the mother liquor. A little more nitric acid is also used. The AO yield increases from approx. 89% to approx. 93%. It is also possible to work with a higher concentration.
- trimer cyclic cyclohexanone peroxide (tCHP) is produced.
- the product is not isolated and is converted to pure dCHP in the second step.
- Glacial acetic acid 100 g is added to the solution of the tCHP in isododecane.
- Nitric acid 85 g is added dropwise at 30 ° C. and the mixture is stirred at 40 ° C. for two hours. Then it is cooled to 25 ° C., water is added and the precipitate formed is filtered off. The product is washed with water. Yield: 175 g of water-moist (approx. 90%) dCHP; GC content: 99%.
