Description
Foreliggende oppfinnelse vedrører en fremgangsmåte for hydroksylering av aromatiske hydrokarboner valgt blant gruppen av fenol, toluen, anisol, xylener, mesitylen, benzen, nitrobenzen, etylbenzen og acetanilid, ved omsetning med hydrogenperoksyd i nærvær av syntetiske zeolitt-katalysatorer bestående av krystallinsk silisiumoksyd modifisert ved at silisiumatomer er utvekslet med og/eller erstattet av elementer valgt blant Cr, Be, Ti, V, Mn, Fe, Co, Zn, Zr, Rh, Ag, Sn, Sb, og B, og det særegne ved fremgangsmåten i henhold til oppfinnelsen er at omsetningen gjennomføres i nærvær av aceton, foretrukket ved tilbake-løpstemperaturen. Disse trekk ved oppfinnelsen fremgår av patentkravet. The present invention relates to a method for the hydroxylation of aromatic hydrocarbons selected from the group of phenol, toluene, anisole, xylenes, mesitylene, benzene, nitrobenzene, ethylbenzene and acetanilide, by reaction with hydrogen peroxide in the presence of synthetic zeolite catalysts consisting of crystalline silicon oxide modified by silicon atoms are exchanged with and/or replaced by elements selected from Cr, Be, Ti, V, Mn, Fe, Co, Zn, Zr, Rh, Ag, Sn, Sb, and B, and the peculiarity of the method according to the invention is that the reaction is carried out in the presence of acetone, preferably at the reflux temperature. These features of the invention appear in the patent claim.
Den direkte hydroksylering av aromatiske hydrokarboner med The direct hydroxylation of aromatic hydrocarbons with
hjelp av hydrogenperoksyd har vært kjent i noen tid og gjennomføres i nærvær av en katalysator generelt valgt fra overgangsmetallene. using hydrogen peroxide has been known for some time and is carried out in the presence of a catalyst generally selected from the transition metals.
Denne reaksjon har imidlertid visse ulemper, inklusive de følgende: - lav selektivitet med hensyn til hydrogenperoksydet pga. dets delvise spaltning pga. metallionene, - lav selektivitet med hensyn til utgangshydrokarbonet pga. koblingsreaksjoner med intermediat-organiske radikaler, - i det spesielle tilfellet med fenol er de dannede difenoler lettere oksyderbare enn selve fenolen og dette resul-terer uunngåelig i betraktelig omdannelsesreduksjon. However, this reaction has certain disadvantages, including the following: - low selectivity with respect to the hydrogen peroxide due to its partial cleavage due to the metal ions, - low selectivity with regard to the starting hydrocarbon due to coupling reactions with intermediate organic radicals, - in the special case of phenol, the diphenols formed are more easily oxidizable than the phenol itself and this inevitably results in a considerable reduction in conversion.
Ved å gjennomføre reaksjonen mellom et aromatisk hydrokarbon og hydrogenperoksyd er det også kjent å anvende et surt alumino-silikat som er blitt underkastet doping eller delvis modifisert ved hjelp av sjeldne jordartmetaller (US-patentskrift 3.580.956). By carrying out the reaction between an aromatic hydrocarbon and hydrogen peroxide, it is also known to use an acidic aluminosilicate which has been subjected to doping or partially modified by means of rare earth metals (US patent 3,580,956).
Selv om det forbedrer yteevnen ved de nevnte systemer, vil imidlertid ikke bruken av dette katalytiske material full-stendig eliminere dannelse av betraktelige mengder av unyttige biprodukter, og disse påvirker negativt de ende-lige resultater og lønnsomheten av hele prosenten. Although it improves the performance of the mentioned systems, the use of this catalytic material will not completely eliminate the formation of considerable amounts of useless by-products, and these negatively affect the final results and the profitability of the whole percentage.
Det er fra den norske patentansøkning nr. 81.3025 også kjent at det er mulig å binde hydroksylgrupper til aromatiske kjerner ved å omsette det angjeldende aromatiske hydrokarbon med hydrogenperoksyd, uten noen av de nevnte ulemper, ved gjennomføring av reaksjonen i nærvær av syntetiske zeolitter inneholdende enten erstattede eller utvekslede heteroatomer. It is also known from the Norwegian patent application no. 81.3025 that it is possible to bind hydroxyl groups to aromatic nuclei by reacting the aromatic hydrocarbon in question with hydrogen peroxide, without any of the aforementioned disadvantages, when carrying out the reaction in the presence of synthetic zeolites containing either substituted or exchanged heteroatoms.
Zeolittmaterialer som kan anvendes ved fremgangsmåten i henhold til den nevnte patentansøkning kan velges f.eks. Zeolite materials that can be used in the method according to the aforementioned patent application can be chosen, e.g.
fra den som er beskrevet i den norske patentansøkning nr. 79.2059. from the one described in the Norwegian patent application no. 79.2059.
Den sistnevnte ansøkning beskriver et syntetisk material bestående av krystallinsk silisiumoksyd modifisert ved nærvær av elementer som går inn i det krystallinske silisium-oksydgitter for å erstatte noen silisiumatomer. The latter application describes a synthetic material consisting of crystalline silicon oxide modified by the presence of elements that enter the crystalline silicon oxide lattice to replace some silicon atoms.
De modifiserende elementer velges fra Cr, Be, Ti, V, Mn, Fe, Co, Zn, Rh, Ag, Sn, Sb, B.'The modifying elements are selected from Cr, Be, Ti, V, Mn, Fe, Co, Zn, Rh, Ag, Sn, Sb, B.'
Den nevnte patentansøkning vedrører også fremgangsmåter for fremstilling av disse syntetiske materialer og det vises til denne ansøkning for mulige ytterligere detaljer og for en bedre forståelse av strukturen av selve materi-alet. The aforementioned patent application also relates to methods for the production of these synthetic materials and reference is made to this application for possible further details and for a better understanding of the structure of the material itself.
I forbindelse med hydroksyleringsprosessen som er gjen-stand for den nevnte norske patentansøkning nr. 81,3025 In connection with the hydroxylation process which is the subject of the aforementioned Norwegian patent application no. 81,3025
er det viktig å legge vekt på den store fordel med å gjen-nomføre prosessen som skyldes bruken av av syntetiske it is important to emphasize the great advantage of carrying out the process due to the use of synthetics
zeolitter, idet denne fordel består i muligheten av å sty-re reaksjonen mot dannelse av et produkt snarere enn et annet ved enkelt valg av en bestemt modifisert zeolitt. zeolites, as this advantage consists in the possibility of directing the reaction towards the formation of one product rather than another by simply choosing a particular modified zeolite.
F.eks. i tilfellet med fenolhydroksylering anvendes et porøst krystallinsk syntetisk material dannet fra silisi-um og titanoksyder, og bruken av et slikt material mulig-gjør oppnåelse av en blanding av hydrokinon og pyrokatekol i forhold libeller mer. E.g. in the case of phenol hydroxylation, a porous crystalline synthetic material formed from silicon and titanium oxides is used, and the use of such a material makes it possible to obtain a mixture of hydroquinone and pyrocatechol in more equal proportions.
Slike krystallinske syntetiske materialer er hvilke som helst av de materialer som er kjent fra den norske patent-ansøkning nr. 80.3859. Such crystalline synthetic materials are any of the materials known from Norwegian patent application no. 80.3859.
Reaksjonen mellom deta aromatiske hydrokarbon og hydrogenperoksyd gjennomføres ved en temperatur mellom 80 og 120°c i nærvær av hydrokarbonet enten alene eller med et løsnings-middel valgt fra vann, metanol, eddiksyre, isopropanol eller acetonitril. The reaction between the aromatic hydrocarbon and hydrogen peroxide is carried out at a temperature between 80 and 120°c in the presence of the hydrocarbon either alone or with a solvent selected from water, methanol, acetic acid, isopropanol or acetonitrile.
Hydrokarbonsubstrater som kan behandles ved den foreliggende oppfinnelse er fenol, toluen, anisol, xylener, mesitylen, benzen, nitrobenzen, etylbenzen,og acetanilid, og ved å gjennomføre reaksjonen av angjeldende hydrokarbon i nærvær av aceton, kan man anvende meget høye tilførselstakter og oppnå ytterst høye utbytter. Hydrocarbon substrates that can be treated by the present invention are phenol, toluene, anisole, xylenes, mesitylene, benzene, nitrobenzene, ethylbenzene, and acetanilide, and by carrying out the reaction of the hydrocarbon in question in the presence of acetone, very high feed rates can be used and extremely high yields.
Mengden av tunge biprodukter er meget liten. The amount of heavy by-products is very small.
Reaksjonen gjennomføres foretrukket ved tilbakeløpstempe-ratur. The reaction is preferably carried out at reflux temperature.

Resultatene er som følger: The results are as follows:
En kombinasjon av læren for eksempel i DE-25 14 742 og norsk patentansøkningnr. 813025 kunne ikke føre til den foreliggende oppfinnelse da det tyske dokument viser bruken av et keton (også aveton) ved hydroksylering av fenoliske forbindelser i nærvær av hydrogenperoksyd og en katalysator som er svovelsyre eller en sulfonsyre eller salter av disse syrer. A combination of the teaching, for example, in DE-25 14 742 and Norwegian patent application no. 813025 could not lead to the present invention as the German document shows the use of a ketone (also avetone) in the hydroxylation of phenolic compounds in the presence of hydrogen peroxide and a catalyst which is sulfuric acid or a sulphonic acid or salts of these acids.
Syntesebetingelsene er klart forskjellige fra betingelsene ved den foreliggende oppfinnelse hvor det ikke på noen måte er tilstede svovelsyre sulfonsyre eller salter derav, idet katalysator ved oppfinnelsen er en syntetisk zeolitt. The synthesis conditions are clearly different from the conditions of the present invention where sulfuric acid, sulphonic acid or salts thereof are not present in any way, as the catalyst of the invention is a synthetic zeolite.
Dette utdypes ved en nærmere drøftelse i sammenheng med de etterfølgende eksempler 8A og 9A i henhold til oppfinnelsen og sammenlikningseksempler 8B og 9B. This is elaborated by a closer discussion in connection with the following examples 8A and 9A according to the invention and comparative examples 8B and 9B.
Nærmere drøftelse Further discussion
I det følgende anføres ytterligere eksempler som viser at aceton ved den foreliggende oppfinnelse ikke på noen måte er noen glatt ekvivalent med det metylisobutylketon som anvendes som keton i den norske patentansøkning nr. 81c3025. In the following, further examples are given which show that acetone in the present invention is in no way a smooth equivalent to the methyl isobutyl ketone used as ketone in the Norwegian patent application no. 81c3025.
I eks. 8A i samsvar med oppfinnelsen utgjør E^C^-utbyttet allerede etter en time med 73,9% nesten 74% og vektforholdet mellom tjæreaktige rester/tjæreaktige +difenoler utgjør bare 7,8:100. In ex. 8A in accordance with the invention, the E^C^ yield is already after one hour with 73.9% almost 74% and the weight ratio between tarry residues/tarry +diphenols is only 7.8:100.
Ved sammenlikningseksempel 8B er I^C^-utbyttet etter 1 times reaksjonstid bare 50* og heller ikke etter 2 timers reasjonstid når J^C^-utbyttet med bare 68* den verdi som oppnås ved oppfinnelsen etter bare den halve reaksjonstid. Videre dannes i sammenlikningseksempelet 8B ved arbeidsmåten i henhold til den norske patentansøkning nr.81.3025 myemere tjæreaktige rester som vises ved forholdet mellom tjæreaktige rester/-tjæreaktige rester +difenoler = 40,55: 100. In comparative example 8B, the I^C^ yield after 1 hour's reaction time is only 50*, nor after 2 hours' reaction time does the J^C^ yield with only 68* reach the value obtained by the invention after only half the reaction time. Furthermore, in the comparison example 8B, by the working method according to the Norwegian patent application no. 81.3025, more tar-like residues are formed, which is shown by the ratio between tar-like residues/-tar-like residues + diphenols = 40.55: 100.
Sammenlikningen mellom eksemplene 9A og 9B viser likeledes at arbeidsmåten i henhold til oppfinnelsen i nærvær av aceton fører til et vesentlig høyere f^C^-utbytte enn ved arbeidsmåten i henhold til den norske patentansøkning nr. 81.3025, nemlig 40,55* i forhold til 29,14*. The comparison between examples 9A and 9B likewise shows that the working method according to the invention in the presence of acetone leads to a significantly higher f^C^ yield than with the working method according to the Norwegian patent application no. 81.3025, namely 40.55* in relation to 29.14*.
Disse resultater er absolutt overraskende og er heller ikke indikert eller nærliggende i forhold til den nevnte DE-AS 25 14 742. Ved den der beskrevne fremgangsmåte for fremstilling åv toverdige fenolderivater, som kan gjennom-føres i nærvær av tallrike ketoner, foretrekkes ganske åpenbart metylisobutylketon, betegnet med den systematiske betegnelse 4-metyl-2-pentanon, som vist i eksemplene 2,3, These results are absolutely surprising and are also not indicated or close in relation to the aforementioned DE-AS 25 14 742. In the process described there for the production of divalent phenol derivatives, which can be carried out in the presence of numerous ketones, methyl isobutyl ketone is quite obviously preferred , designated by the systematic designation 4-methyl-2-pentanone, as shown in examples 2,3,
7 til 35, 38,41 til 47 og 49 til 56. Eksempel 1 i den tyske puplikasjon gir ikke den fagkyndige noen henvisning om at det selv ved overføring av arbeidsmåten i henhold til denne publikasjon-hydroksylering av enverdige fenolderivater i nærvær av et keton - til fremgangsmåten i henhold til den norske patentansøkning - hydroksylering av aromatiske hydrokarboner i nærvær av bestemte syntetiske zeolitter - kunne det med aceton som keton oppnås særlig gode resultater, ettersom totalutbyttene av pyrokatekol og .hydrokinon i eksemplene 1 og 2 i DE-AS 25 14 742 bare skiller seg med 0,6*. 7 to 35, 38,41 to 47 and 49 to 56. Example 1 in the German publication does not give the expert any indication that even when transferring the working method according to this publication - hydroxylation of monovalent phenol derivatives in the presence of a ketone - for the method according to the Norwegian patent application - hydroxylation of aromatic hydrocarbons in the presence of certain synthetic zeolites - particularly good results could be achieved with acetone as a ketone, as the total yields of pyrocatechol and .hydroquinone in examples 1 and 2 in DE-AS 25 14 742 only differ by 0.6*.
Fremgangsmåten i henhold til oppfinnelsen kan således ikke enkelt sluttes fra en mulig kombinering av de to publika-sjoner. Det var tvert om nødvendig å arbeide seg frem til en lære i motsetning til læren i den norske patent-ansøkning (hvor det som keton anvendes metylisobutylketon) ved at det anvendes et annet, ganske bestemt keton ved hydroksyleringen av aromatiske hydrokarboner henholdsvis aromatiske forbindelser i nærvær av andre katalysatorer enn dem som anvendes i henhold til den norske patentansøk-ning. The method according to the invention cannot therefore be simply concluded from a possible combination of the two publications. On the contrary, it was necessary to work towards a teaching contrary to the teaching in the Norwegian patent application (where methyl isobutyl ketone is used as the ketone) by using another, quite specific ketone in the hydroxylation of aromatic hydrocarbons or aromatic compounds in the presence of catalysts other than those used in accordance with the Norwegian patent application.
