Definitions
- the present invention relates to a process for producing cyclododecanone, a process for purifying cyclododecane and a process for producing laurolactam.
- Cyclododecanone (CDON) is prepared by the known methods of Bashkirow oxidation of
- Cyclododecane (CDAN, Oenbrink, G. and Schiffer, T., 2009. Cyclododecanol, Cyclododecanone, and Laurolactam, Ullmann's Encyclopedia of Industrial Chemistry).
- EP-A-2772478 (US 9000223) describes the epoxidation of cyclododecene (CDEN) to cyclododecane epoxide
- CDANepoxide CDANepoxide
- CDOL cyclododecanol
- saturated and unsaturated linear and cyclic C1-alkanes are also formed.
- further oxidized species are formed, among others.
- the linear 2-undecanone and the cyclic ring ethers 13-oxabicyclo [8.2.1] tridecane (1, 4-C12 ethers) and 13-oxabicyclo [7.3.1] tridecane (1, 5-C12 ethers) with a concentration each up to 1 wt .-%, based on the obtained CDON-containing mixture.
- Components are transferred in comparison to CDAN lighter or heavier species, in order to distill them easier in the following.
- linear ketone are offered as reactive processes, the hydrogenation of the keto group to the alcohol to suitable
- the 1, 5-C12 ether in no process, the 2-undecanone can be separated only in one process.
- the object of the present invention was now to provide a method for the production of CDON, in which it is possible to separate impurities formed simultaneously. Ideally, CDAN present after the reaction to CDON should be isolated.
- the CDAN produced in the described preparation process which can not be purified by distillation or combinations of reaction with distillation, can be obtained by crystallization with high purity.
- CDAN Cyclododecane
- the CDAN-containing fraction may contain impurities such as 13-oxabicyclo [8.2.1] tridecane, 13-oxabicyclo [7.3.1] tridecane, 2-undecanone or mixtures thereof. Especially this one
- the mixture of CDOL and CDON can be obtained by the successive steps i) hydrogenation of CDT to CDAN, and ii) oxidation of CDAN to the mixture of CDOL and CDON.
- the mixture can be obtained by the sequential steps I) hydrogenation of CDT to cyclododecene (CDEN), II) epoxidation of CDEN to cyclododecane epoxide (CDAN epoxide), and II) rearrangement of CDAN epoxide to the mixture of CDOL and CDON become.
- the crystallized CDAN from step d) can be used again.
- it can be oxidized to a mixture of CDOL and CDON.
- it is possible to convert the CDAN with nitrosyl chloride to cyclododecanone oxime.
- CDON-containing mixture obtained after dehydrogenation of CDOL to CDON (step b) is subsequently distilled (step c).
- a fraction is obtained, which in addition to CDAN contains other compounds which have CDAN approximately the same or higher vapor pressure (CDAN-containing fraction).
- CDAN-containing fraction contains other compounds which have CDAN approximately the same or higher vapor pressure.
- This fraction contains the impurities mentioned above.
- CDAN lower vapor pressure There remains a fraction with CDAN lower vapor pressure; This fraction contains inter alia the CDON (CDON-containing fraction).
- the CDON For further processing of the CDON, it is advantageous to isolate the CDON from the CDON-containing fraction. For this purpose, it is preferable to separate the CDON by distillation.
- the CDAN-containing mixture in step d) is usually fed to a crystallization unit and crystallized out.
- Suitable methods are melt crystallization or solution crystallization.
- melt crystallization the CDAN contained, for example, in the contaminated CDAN stream partially solidifies on a cooled surface, with the secondary components being able to concentrate in the liquid, so-called mother liquor, and to be separated from the CDAN crystals. Thereafter, by increasing the temperature in the CDAN crystals incorporated impurities are sweated and removed, before finally CDAN is obtained in very high purity by melting.
- the melt crystallization is selected from static crystallization, falling film crystallization or
- the CDAN-containing mixture is first subjected to crystallization and the non-crystallized constituents are removed. This is followed by a temperature increase to dissolve (sweat) contaminants. It remains crystallized CDAN in high concentration.
- the present invention further relates to a process for the purification of CDAN, for example, from the production process for cyclododecanone according to the Bashkirow or the epoxidation process.
- the CDAN contains impurities such as, for example, 13-oxabicyclo [8.2.1] tridecane, 13-oxabicyclo [7.3.1] tridecane, 2-undecanone or mixtures thereof.
- the Purification takes place by means of crystallization, such as, for example, melt crystallization or solution crystallization.
- the current from the oxidation or rearrangement comprises the mixture of CDOL and CDON. Furthermore, about 0-2 wt .-% low boilers (boiling less than CDAN), 5-15 wt .-% CDAN or CDEN, 0-1 wt% medium boilers (between CDAN and CDON boiling), 70-80 wt % CDON, CDOL and high boilers (heavier than CDOL).
- the stream becomes a first
- CDON is first produced from CDT (CDON process according to the invention). Subsequently, the CDON is oximated to cyclododecanone oxime (CDON-oxime). Suitable reactants are
- CDON-oxime for example by means of cyanuric chloride or sulfuric acid to laurolactam.
- CDAN fractions were used which consisted of a CDON-containing
- the CDON-containing mixture was obtained via the epoxidation of CDEN and subsequent rearrangement.
- the CDAN fraction was worked up in the examples in various ways.
- the impurities were determined by gas chromatography with mass spectrometry coupling (GC-MS).
- GC instrument Agilent GC 6890 / Agilent MSD 5973; Separation column 60 m ⁇ 0.25 mm DB-Wax, film 0.25 ⁇ ; Injector: 250 ° C, split 50: 1, 244 kPa helium; Oven temperature 150 ° C - 5 ° C / min - 180 ° C (10 min) - 5 ° C / min - 220 ° C (40 min); Injection 1 ⁇ _ sample; Ionization: electron impact ionization, 70 eV, and chemical ionization with ammonia as reactant gas.
- Example A Acid catalyst (not according to the invention)
- a mixture consisting of CDAN and 2-undecanone was hydrogenated at 200 ° C. under an H2 atmosphere (20 bar) over a Riv catalyst for 68 h.
- the 2-undecanone was reacted to 97%, based on the feed used.
- the crystallization according to the invention allowed the purity of CDAN to be increased from 97.5% to 99.0%.
- the proportion of by-products in the CDAN was reduced from 2.5% to 1, 0%;
- the difficult to separate substances 2-undecanone and the two C12 ethers could be reduced or no longer detected.
- the crystallization according to the invention enabled the purity of CDAN to be increased from 93.1% to 97.6%.
- the share of by-products in the CDAN was reduced from 6.9% to 2.4%.
- 2-undecanone and the C12 ethers were no longer detectable after crystallization.
