下記一般式(1)で表される脂環式ジカルボン酸無水物を、配位子となりうる化合物の共存下でニッケル錯体を触媒として脱カルボニル、脱炭酸し、下記一般式(2)で表される環状オレフィン化合物を製造する方法であって、前記反応は、生成した前記環状オレフィン化合物を反応系外に除去しながら行なうことを特徴とする。The alicyclic dicarboxylic acid anhydride represented by the following general formula (1) is decarbonylated and decarboxylated using a nickel complex as a catalyst in the presence of a compound that can be a ligand, and represented by the following general formula (2).

Description
本発明は、脂環式ジカルボン酸無水物から環状オレフィンを製造する方法に関するものである。 The present invention relates to a method for producing a cyclic olefin from an alicyclic dicarboxylic acid anhydride.
環状オレフィンは、エチレンなどの低級オレフィンとの共重合や開環メタセシス重合により得られるCOCの原料として有用である。環状オレフィンの製造法に関しては多くの方法が知られているが、その中で(1)脂環式ジカルボン酸無水物の脱カルボニル、脱炭酸反応、あるいは(2)脂環式ジカルボン酸無水物の加水分解によって得られるジカルボン酸誘導体の酸化的脱炭酸反応がある。 The cyclic olefin is useful as a raw material for COC obtained by copolymerization with a lower olefin such as ethylene or ring-opening metathesis polymerization. There are many known methods for producing cyclic olefins, including (1) decarbonylation and decarboxylation of alicyclic dicarboxylic acid anhydrides, or (2) alicyclic dicarboxylic acid anhydrides. There is an oxidative decarboxylation reaction of a dicarboxylic acid derivative obtained by hydrolysis.
これらの反応の原料となる脂環式ジカルボン酸無水物は、共役ジエン化合物と無水マレイン酸類とのDiels−Alder反応によって得ることができる。一般にDiels−Alder反応において無水マレイン酸類は高い反応性を示すことから、付加体が良好な収率で得られる場合が多い。したがってこれらの脂環式ジカルボン酸無水物あるいはそれらの加水分解によって得られるジカルボン酸誘導体から効率良く脱カルボニルあるいは脱炭酸を行なうことができれば、種々のジエン化合物と無水マレイン酸類との組み合わせにより多様な構造をもつ環状オレフィンを高収率で合成することが期待できる。 The alicyclic dicarboxylic acid anhydride used as a raw material for these reactions can be obtained by a Diels-Alder reaction between a conjugated diene compound and maleic anhydrides. In general, maleic anhydrides are highly reactive in the Diels-Alder reaction, so that adducts are often obtained in good yields. Therefore, if the decarbonylation or decarboxylation can be efficiently performed from these alicyclic dicarboxylic acid anhydrides or dicarboxylic acid derivatives obtained by hydrolysis thereof, various structures can be obtained by combining various diene compounds and maleic anhydrides. It can be expected to synthesize cyclic olefins having a high yield.
しかしながら(1)、(2)のいずれの公知方法も環状オレフィンを工業的に有利に製造するには問題点が多い。 However, both of the known methods (1) and (2) have many problems in producing a cyclic olefin industrially advantageously.
(1)の方法としては、例えばJ.Org.Chem.,41,887(1975)記載のニッケルカルボニル錯体を用いる方法が挙げられるが、高価なニッケルカルボニル錯体を1当量以上必要とするという問題がある。触媒量のニッケルカルボニル錯体を用いた例(J.Org.Chem.,43,3074(1978))もあるが、触媒量は原料酸無水物に対して20mol%と多く、また溶媒を厳密に精製し、触媒も使用前に新たに調製したものを使用しなければならないなど満足し得るものではない。 As a method of (1), for example, J.A. Org. Chem. , 41, 887 (1975). However, there is a problem that one equivalent or more of an expensive nickel carbonyl complex is required. There is also an example using a catalytic amount of nickel carbonyl complex (J. Org. Chem., 43, 3074 (1978)), but the catalytic amount is as high as 20 mol% with respect to the raw acid anhydride, and the solvent is strictly purified. However, it is not satisfactory that the catalyst must be newly prepared before use.
(2)の方法としては、例えば(a)J.Am.Chem.Soc.,74,4370(1952)記載の酸化鉛(IV)を用いる方法、(b)Org.React.,19,279(1972)記載の酢酸鉛(IV)を用いる方法、(c)(Tetrahedron Lett.,4447(1976)記載の酸化銅(I)と2,2'−ビピリジルを用いる方法、(d)Tetrahedron Lett.,5117(1968)記載の電気分解による方法などが挙げられる。 As a method of (2), for example, (a) J. et al. Am. Chem. Soc. , 74, 4370 (1952), (b) Org. React. , 19, 279 (1972), using lead acetate (IV), (c) (Tetrahedron Lett., 4447 (1976) using copper (I) oxide and 2,2′-bipyridyl, ) Electrolytic method described in Tetrahedron Lett., 5117 (1968).
しかしながら、これらの方法も様々な問題点を有している。
(a)では毒性の高い酸化鉛(IV)を原料であるジカルボン酸に対して1当量以上必要とする上に収率が非常に低いという問題がある。However, these methods also have various problems.
In (a), there is a problem that one or more equivalents of highly toxic lead (IV) oxide is required with respect to the raw material dicarboxylic acid and the yield is very low.
(b)では、(a)に比して収率は高いものの、転位反応が起こりやすいため満足し得るものとは言えず、同様に毒性の高い酢酸鉛(IV)を原料ジカルボン酸に対して1当量以上必要とするという問題がある。 In (b), although the yield is higher than in (a), it cannot be said to be satisfactory because the rearrangement reaction easily occurs. Similarly, highly toxic lead (IV) is used with respect to the raw dicarboxylic acid. There is a problem that one equivalent or more is required.
(c)においても原料ジカルボン酸に対して酸化銅(I)を2当量以上、2,2'−ビピリジルを1当量以上必要とするという問題がある。 Even in (c), there is a problem that 2 equivalents or more of copper oxide (I) and 1 equivalent or more of 2,2′-bipyridyl are required for the raw material dicarboxylic acid.
(d)では電極に高価な白金を用いる必要があり、また反応液中の原料濃度が高いと生成物の収率が極端に低下するため希薄条件下で行なわなければならず、工業的規模で行うには生産効率が悪いなどの問題を有している。 In (d), it is necessary to use expensive platinum for the electrode, and if the raw material concentration in the reaction solution is high, the yield of the product is extremely reduced, so it must be performed under dilute conditions. To do so, it has problems such as poor production efficiency.
このように何れの方法も高価な原料、あるいは設備を必要とするためコストがかかる上、生成物の分離精製が煩雑であるという問題を有しており、さらに多量の廃棄物を排出するため環境問題の観点からも好ましいものではない。
しかして、本発明の目的は、前記従来技術に鑑み、COCなどのポリオレフィンの原料として有用な環状オレフィンを、工業的に有利に製造する方法を提供することにある。 Therefore, in view of the prior art, an object of the present invention is to provide a method for industrially advantageously producing a cyclic olefin useful as a raw material for polyolefin such as COC.
本発明者らは、前記の課題を解決するため鋭意検討を重ねた結果、脂環式ジカルボン酸無水物の脱カルボニル、脱炭酸反応によって環状オレフィンを製造する方法において、配位子となりうる化合物の共存下でニッケル錯体を触媒として使用し、生成する環状オレフィンを反応系外に除去することにより、高い選択率で、高純度の環状オレフィンを製造することが可能であることを見出し、本発明を完成するに至った。 As a result of intensive studies in order to solve the above-mentioned problems, the present inventors have found that a compound that can be a ligand in a method for producing a cyclic olefin by decarbonylation and decarboxylation of an alicyclic dicarboxylic acid anhydride. By using a nickel complex as a catalyst in the coexistence and removing the generated cyclic olefin out of the reaction system, it was found that it is possible to produce a high-purity cyclic olefin with high selectivity. It came to be completed.

本発明においては、高い選択率で、高純度の目的物質を得る観点から、一般式(5)または(6)で表される配位子となりうる化合物を用いることが好ましい。 In the present invention, it is preferable to use a compound that can be a ligand represented by the general formula (5) or (6) from the viewpoint of obtaining a target substance with high selectivity and high purity.
本発明においては、ニッケル錯体触媒の安定性を向上させるため、配位子となりうる化合物を過剰に共存させることが重要である。配位子となりうる化合物の量が少なすぎると触媒の安定性が低下する。一方、配位子の量が多い場合には、触媒の安定性が使用量に比例して向上するわけではなく不経済であったり、反応速度が低下する傾向が認められる。 In the present invention, in order to improve the stability of the nickel complex catalyst, it is important that a compound capable of being a ligand coexists excessively. If the amount of the compound that can be a ligand is too small, the stability of the catalyst is lowered. On the other hand, when the amount of the ligand is large, the stability of the catalyst is not improved in proportion to the amount used, but it is uneconomical or the reaction rate tends to decrease.
したがって、配位子となりうる化合物の使用量はその種類によって必ずしも一定ではないが、通常、ニッケル錯体触媒1モルあたり10〜500モルであり、好ましくは20〜200モルである。 Therefore, the amount of the compound that can be a ligand is not necessarily constant depending on the type, but is usually 10 to 500 mol, preferably 20 to 200 mol, per mol of the nickel complex catalyst.
配位子となりうる化合物を上記の量で用いることにより、高い選択率で、高純度の環状オレフィンを製造することができる。さらに、この範囲内であれば、この化合物自身を溶媒として用いてもよい。その場合使用される化合物は、目的化合物に対して安定であり、かつ、比較的安価なものが好ましい。中でもトリフェニルホスフィンは有用な化合物の一つである。 By using the compound that can be a ligand in the above amount, a high-purity cyclic olefin can be produced with high selectivity. Further, within this range, the compound itself may be used as a solvent. The compound used in that case is preferably stable with respect to the target compound and relatively inexpensive. Among them, triphenylphosphine is one of useful compounds.
これらの配位子となりうる化合物は単独で用いてもよいが、いずれか二種以上の混合物として用いてもよい。これらの配位子となりうる化合物の混合物を用いる場合、それらを任意の割合で混合してもよいが、これらの化合物の総使用量がニッケル錯体触媒1モルに対して上記の範囲内になることが好ましい。 These compounds that can be ligands may be used alone or as a mixture of any two or more thereof. When using a mixture of compounds that can become these ligands, they may be mixed in an arbitrary ratio, but the total amount of these compounds used is within the above range with respect to 1 mol of the nickel complex catalyst. Is preferred.
反応温度は高いほうが反応速度の点では有利であるが、高すぎると触媒の分解や生成物である環状オレフィンの転位、重合などの好ましくない副反応を引き起こして選択率の低下を招く恐れがある。したがって通常100〜300℃、特に150〜250℃で反応を行なうのが好ましい。 A higher reaction temperature is advantageous in terms of reaction rate. However, if the reaction temperature is too high, it may cause undesirable side reactions such as decomposition of the catalyst, rearrangement of the cyclic olefin product, polymerization, and the like, leading to a decrease in selectivity. . Therefore, it is usually preferable to carry out the reaction at 100 to 300 ° C., particularly 150 to 250 ° C.
本発明においては、ニッケル錯体触媒の活性低下を抑制するため、さらには生成する環状オレフィン化合物の熱履歴を少なくすることによって選択率を高めるため、生成物をできるだけ速やかに反応系外に除去することが重要である。したがって反応蒸留方式を採用することが望ましい。 In the present invention, the product is removed from the reaction system as quickly as possible in order to suppress the decrease in the activity of the nickel complex catalyst, and further to increase the selectivity by reducing the thermal history of the cyclic olefin compound to be produced. is important. Therefore, it is desirable to employ a reactive distillation method.
反応圧力は生成するオレフィンの沸点に大きく依存するが、生成物の反応系外からの速やかな除去が達成される限りにおいては特に制限はない。生成物の沸点が低い場合は、常圧で反応させることができる。一方、生成物の沸点が高い場合は、減圧下で反応を行なうことが好ましい。 The reaction pressure largely depends on the boiling point of the olefin to be produced, but is not particularly limited as long as rapid removal of the product from the outside of the reaction system is achieved. When the boiling point of the product is low, the reaction can be performed at normal pressure. On the other hand, when the boiling point of the product is high, the reaction is preferably performed under reduced pressure.
一般式(1)の脂環式ジカルボン酸無水物から得られる一般式(2)で表される環状オレフィン化合物は、気体の形で取り出された後、凝縮によりCOとCO2を含むガスから分離される。このようにして得られる粗製の環状オレフィン化合物は、必要に応じて蒸留などによりさらに精製してもよい。The cyclic olefin compound represented by the general formula (2) obtained from the alicyclic dicarboxylic acid anhydride of the general formula (1) is taken out in the form of a gas and then separated from the gas containing CO and CO 2 by condensation. Is done. The crude cyclic olefin compound thus obtained may be further purified by distillation or the like, if necessary.
反応に際しては、配位子となりうる化合物自身が溶媒の役割を担うことができる場合、それ以外の溶媒を用いることなく反応を行ってもよいが、必要に応じて新たに溶媒を用いても差し支えない。 In the reaction, if the compound that can be a ligand itself can play the role of a solvent, the reaction may be performed without using any other solvent, but a new solvent may be used if necessary. Absent.
溶媒としては、原料、触媒、および配位子となりうる化合物に対して不活性な溶媒であれば、任意のものを使用することができる。例えば、ジエチレングリコールジメチルエーテル、トリエチレングリコールジメチルエーテル、ジフェニルエーテル、アニソール、ベラトロール等のエーテル類、テトラリン、ナフタレン等の芳香族炭化水素類、ニトロベンゼン、ベンゾニトリル、N−メチルピロリドン、ジメチルイミダゾリジノン等の非プロトン性極性溶媒などが挙げられる。 As the solvent, any solvent can be used as long as it is inert to the raw material, the catalyst, and the compound that can be a ligand. For example, ethers such as diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, diphenyl ether, anisole and veratrol, aromatic hydrocarbons such as tetralin and naphthalene, aprotic such as nitrobenzene, benzonitrile, N-methylpyrrolidone and dimethylimidazolidinone Examples include polar solvents.
溶媒(または配位子となりうる化合物)は、生成物である環状オレフィンと容易に分離できるものが好ましく、一般には生成する環状オレフィンよりも高沸点のものが使用される。上記のような溶媒を使用すれば、反応混合物から目的物である環状オレフィンを含む生成物を反応蒸留によって分離する際、触媒と配位子となりうる化合物を溶解している反応液中からの溶媒(または配位子となりうる化合物)の留出を抑制することができるため、これらの溶媒(または配位子となりうる化合物)を新たに供給する必要がなく、また、生成物の煩雑な分離精製を回避できるという点からも有利である。 The solvent (or a compound that can be a ligand) is preferably one that can be easily separated from the product cyclic olefin, and generally has a higher boiling point than the cyclic olefin to be produced. When a solvent such as the above is used, when the product containing the target cyclic olefin is separated from the reaction mixture by reactive distillation, the solvent from the reaction solution in which the catalyst and the compound capable of being a ligand are dissolved. Since distillation of (or a compound that can be a ligand) can be suppressed, there is no need to newly supply these solvents (or compounds that can become a ligand), and complicated separation and purification of the product. This is also advantageous in that it can be avoided.
反応は酸素や水分を除いた状態で行なうことが好ましく、通常、窒素あるいはアルゴンのような不活性雰囲気下で行なわれる。 The reaction is preferably carried out without oxygen or moisture, and is usually carried out in an inert atmosphere such as nitrogen or argon.
反応はバッチ方式、あるいは、ニッケル錯体触媒、配位子となりうる化合物、原料であるジカルボン酸無水物、および溶媒を反応器に連続的に供給する連続式の何れの方式においても実施することができる。 The reaction can be carried out either in a batch system or in a continuous system in which a nickel complex catalyst, a compound capable of becoming a ligand, a raw material dicarboxylic acid anhydride, and a solvent are continuously supplied to a reactor. .
