Description
Fremgangsmåte for fremstilling av cyklodekanol-(l)-on(6). Process for the preparation of cyclodecanol-(1)-one (6).
Dekalin kan brukes som billig og lett Decalin can be used as cheap and easy
tilgjengelig utgangsmaterial for to-kaprinlaktam, som lar seg polymerisere til det teknisk verdifulle polyamid 10, jfr. A. Mul-ler og R. Pfluger, Kunststoffe 50, 1960, side 205. Fra dette blir co-kaprinlaktamet oppnådd ved en fremganksmåte som omfatter flere trinn: available starting material for to-caprine lactam, which can be polymerized into the technically valuable polyamide 10, cf. A. Muller and R. Pfluger, Kunststoffe 50, 1960, page 205. From this, the co-caprine lactam is obtained by a process comprising several steps:
a) Oksydering av dekalin I til dekalinperoksyd II, forestring av dette med eddik-syreanhydrid, b) omlagring av det dekalolperacetat a) Oxidation of decalin I to decalin peroxide II, esterification of this with acetic anhydride, b) rearrangement of the decalol peracetate
III som dannes til acetat av 1-oksy-l, 6-oksido-cyklodekan IV, III which is formed into acetate of 1-oxy-1, 6-oxido-cyclodecane IV,
c) alkalisk forsåpning av dette acetat til cyklodekanol-(l)-on(6) V, som på kjent c) alkaline saponification of this acetate to cyclodecanol-(l)-one(6) V, as in known
måte kan overføres til cyklodekanon VI, manner can be transferred to cyclodecanone VI,
d) oksimering av cyklodekanonet og Beckmann-omlagring av oksimet til d) oximation of the cyclodecane and Beckmann rearrangement of the oxime to
kaprinlaktan VIII. caprine lactan VIII.
Reaksjonsmekanismen for den sure omlagring av estere av dekalinperoksyd II til den tilsvarende 1,6-oksidoforbindelse IV er nærmere undersøkt. The reaction mechanism for the acidic rearrangement of esters of decalin peroxide II to the corresponding 1,6-oxido compound IV has been investigated in more detail.
Det har nå vist seg at denne bekjente syntese av w-kaprinlaktam kan forenkles betydelig ved at enten oksyketonet V frem-stilles ved en ett-trinns reaksjon direkte fra peroksydet II, jfr. eksempel 1, og over-flødiggjør omveien om peracetatet III og oksidoforbindelsen IV, eller ved at peroksydet II først overføres til den bicykliske enoleter IX og denne så forsåpes til oksyketon V, jfr. eksemplene 2 og 3. It has now been shown that this well-known synthesis of w-caprine lactam can be considerably simplified by either producing the oxyketone V in a one-step reaction directly from the peroxide II, cf. example 1, and superfluities the detour about the peracetate III and the oxido compound IV, or by the peroxide II first being transferred to the bicyclic enolet IX and this then being saponified to oxyketone V, cf. examples 2 and 3.
Det er fra det tyske patent nr. 960.459 kjent å omlagre dekalinperoksyd surt, nem-lig i nærvær av alkohol. I henhold til foreliggende oppfinnelse er det imidlertid bare nødvendig med en vandig syreoppløsning, hvilket er mer økonomisk og fører til et renere omlagringsprodukt. I henhold til den kjente prosess må det ønskede oksyketon isoleres, som oksim, mens det i henhold til foreliggende oppfinnelse bare ekstraheres med vann og det oppnådde råprodukt kan renses ved en eneste omkrystallisering fra cykloheksan. It is known from German patent no. 960,459 to store decalin peroxide in an acidic manner, namely in the presence of alcohol. According to the present invention, however, only an aqueous acid solution is required, which is more economical and leads to a cleaner re-storage product. According to the known process, the desired oxyketone must be isolated, as an oxime, while according to the present invention it is only extracted with water and the crude product obtained can be purified by a single recrystallization from cyclohexane.
I henhold til foreliggende oppfinnelse behandles dekalinperoksydet II med sure omlagringskatalysatorer i nærvær av vann, hvorved oksyketonet V dannes direkte, eller omlagringen foretas uten nærvær av vann, hvorved det dannes det destillerbare mel-lomprodukt bicyklisk enoleter IX (7-oksa-(4,4,1) bicyklo-undecen-(l,2)), som kan forsåpes til oksyketon V ved hjelp av for-tynnede syrer. According to the present invention, the decalin peroxide II is treated with acidic rearrangement catalysts in the presence of water, whereby the oxyketone V is formed directly, or the rearrangement is carried out without the presence of water, whereby the distillable intermediate bicyclic enol ether IX (7-oxa-(4,4 ,1) bicyclo-undecene-(1,2)), which can be saponified to oxyketone V by means of dilute acids.
Eksempel 1. Example 1.
5,0 g dekalinperoksyd ble oppløst i 375 ml 67 pst. eddiksyre og oppløsningen oppvarmet til koking i to timer på tilbakeløps-kjøler. Etter avkjøling ble det foretatt inn-damping til tørr tilstand i vakuum (30 mm Hg, maksimaltemperatur 40° C). Fra de-stilleringsresten ble det ved ekstrahering med vann oppnådd rått cyklodekanol-(l)-on(6), som kan omkrystalliseres fra cykloheksan til et rent produkt med smp. 69— 70° C (lit. 70° C). 5.0 g of decalin peroxide was dissolved in 375 ml of 67% acetic acid and the solution was heated to boiling for two hours on a reflux condenser. After cooling, evaporation to dryness was carried out in vacuum (30 mm Hg, maximum temperature 40° C). From the distillation residue crude cyclodecanol-(1)-one (6) was obtained by extraction with water, which can be recrystallized from cyclohexane to a pure product with m.p. 69— 70° C (lit. 70° C).
Utbyttet var 2,65 g, tilsvarende "53 pst. av det teoretisk mulige. The yield was 2.65 g, corresponding to 53 per cent of the theoretically possible.
Eksempel 2. Example 2.
10,0 g dekalinperoksyd ble oppløst i 100 ml benzen og til oppløsningen ble det satt 0,15 g kons. svovelsyre. Den sure oppløs-ning ble oppvarmet i 20 timer til koking på en tilbakeløpskjøler som var forsynt med 10.0 g of decalin peroxide was dissolved in 100 ml of benzene and 0.15 g of conc. sulfuric acid. The acidic solution was heated for 20 hours to boiling on a reflux condenser equipped with
vannutskiller for å fjerne reaksjonsvannet, og etter avkjøling vasket nøytralt med vann. Deretter ble oppløsningsmidlet og re-aksjonsproduktet enoleter IX skilt fra hver-andre ved fraksjonert destillering. Det ble oppnådd 6,45 g enoleter, kp. 94° C ved 14 mm Hg, tilsvarende et utbytte på 72 pst. water separator to remove the water of reaction, and after cooling washed neutrally with water. Then the solvent and the reaction product enolet IX were separated from each other by fractional distillation. 6.45 g of enolet were obtained, b.p. 94° C at 14 mm Hg, corresponding to a yield of 72 per cent.
5,0 g av enoleteren ble oppløst i 50 ml 50 pst. eddiksyre og etter koking av opp-løsningen på tilbakeløpskjøler i to timer ble det som forsåpingsprodukt oppnådd cyklodekanol-(l)-on(6). Dette kan isoleres og renses slik som beskrevet i eksempel 1. Det ble på denne måten oppnådd 5,3 g av oksyketonet, smp. 69—70° C, tilsvarende et utbytte på 95 pst. 5.0 g of the enol ether was dissolved in 50 ml of 50% acetic acid and after boiling the solution in a reflux condenser for two hours, cyclodecanol-(1)-one (6) was obtained as a saponification product. This can be isolated and purified as described in example 1. In this way, 5.3 g of the oxyketone were obtained, m.p. 69-70° C, corresponding to a yield of 95 per cent.
Eksempel 3. Example 3.
10,0 g dekalinperoksyd ble oppløst i 100 ml aceton og oppløsningen blandet med 0,1 g kons. svovelsyre. Etter koking i en time på tilbakeløpskjøler ble oppløsnings-midlet destillert fra, resten opptatt i eter, vasket nøytralt med vann og destillert i vakuum. Det ble på denne måten oppnådd 5,65 g enoleter IX, kp. 94° C ved 14 mm Hg, tilsvarende 63 pst. av det teoretisk mulige. 10.0 g decalin peroxide was dissolved in 100 ml acetone and the solution mixed with 0.1 g conc. sulfuric acid. After boiling for one hour in a reflux condenser, the solvent was distilled off, the residue taken up in ether, washed neutrally with water and distilled in vacuo. In this way, 5.65 g of enolet IX, bp. 94° C at 14 mm Hg, corresponding to 63 percent of what is theoretically possible.
5,0 g av enoleteren ble oppløst i 100 ml 50 pst. eddiksyre og etter koking av oppløs-ningen på tilbakeløpskjøler ble det som forsåpningsprodukt oppnådd cyklodekanol-(l)-on(6). Dette kan isoleres og renses slik som angitt i eksempel 1. Det ble på denne måten oppnådd 5,37 g av oksyketonet, smp. 69—70° C, tilsvarende et utbytte på 96 pst. 5.0 g of the enol ether was dissolved in 100 ml of 50% acetic acid and after boiling the solution in a reflux condenser, cyclodecanol-(1)-one (6) was obtained as a saponification product. This can be isolated and purified as indicated in example 1. In this way, 5.37 g of the oxyketone were obtained, m.p. 69-70° C, corresponding to a yield of 96 per cent.
