本発明のε−カプロラクタムの製造方法では、触媒の存在下で反応を行うことで、反応を促進することが出来る。触媒は貴金属が好ましく、具体的には、パラジウム、白金、金、銅、ルテニウム、ロジウム、コバルト、レニウム、ニッケルが挙げられ、これらのうちの1種類以上を含む合金であってもよい。
本発明における水素、アンモニアは、反応容器に一括添加(バッチ式)しても逐次添加(連続式)してもよく、水素およびアンモニアをそれぞれ単独で添加してもよいし、混合して添加してもよい。
本発明のε−カプロラクタムの製造方法では、溶媒の存在下で反応を行うことができる。使用される溶媒は限定されないが、メタノール、エタノール、ブタノールなどのアルコール系溶媒、四塩化炭素、ジクロロメタン、クロロホルムなどのハロゲン系溶媒、ペンタン、ヘキサン、ヘプタン、オクタン、デカンなどの脂肪族炭化水素系溶媒、ベンゼン、トルエン、キシレンなどの芳香族炭化水素系溶媒、ジメチルエーテル、ジエチルエーテル、1,2−ジメトキシエタン、ジグリム、テトラヒドロフラン、ジオキサンなどのエーテル系溶媒、γブチロラクトン、N−メチルピロリドン、ジメチルスルホキシド、水などが挙げられ、これらのうち2種類以上の混合溶媒でもよい。好ましくは、ジオキサン、ジグリム、テトラヒドロフラン等の非プロトン性溶媒が使用される。
本発明のε−カプロラクタムの製造方法では、加熱条件下で反応を行ってもよい。反応温度は反応容器内温で100℃以上350℃以下が好ましく、より好ましくは、150℃以上300℃以下である。また、反応時間は、反応温度や他の条件に応じて適宜選択されるが、通常、0.5時間〜12時間程度である。
本発明におけるε−カプロラクタムの製造方法では、反応終了後に濾過、抽出、蒸留など通常の分離精製操作によりε−カプロラクタムを回収することができる。水素とアンモニアは反応系にリサイクルしてもよい。また、ε−カプロラクタム以外にアジポアミド(ヘキサン二酸アミド)などの中間体が生成した場合、回収、リサイクルすることでε−カプロラクタムの収率を上げることが出来る。
本発明のε−カプロラクタムの製造方法で得られるε−カプロラクタムは、これを原料としてポリアミドの製造に使用することが出来る。該ポリアミドの製造方法としては、ε−カプロラクタムを開環重合させる公知の方法を適用できる(福本修編、「ポリアミド樹脂ハンドブック」日刊工業出版社(1998年1月)参照)。

本発明で使用した3−ヒドロキシアジピン酸メチルエステル−3,6−ラクトンは化学合成により準備した。
内容量0.2Lのステンレス製オートクレーブ(耐圧ガラス工業社製)に、参考例1で合成したα−ヒドロムコン酸1.0gとジオキサン0.1L(和光純薬社製)と5重量パーセントパラジウム担持したγアルミナ(Pd/γAl2O3、Alfa aser社製)0.05gを添加した。次いで、オートクレーブにアンモニアガスを添加し、オートクレーブの内圧を0.35MPa(ゲージ圧)となるよう調節した後、1000rpmで30分間室温で攪拌した。次いで、攪拌を継続しながら水素を添加し、オートクレーブの内圧を水素の分圧換算で1.35MPa(ゲージ圧)となるよう調節した(全圧(ゲージ圧):1.7MPa)。次いで、オートクレーブ内の温度を250℃で3時間加熱した。反応終了後、室温まで放冷し、オートクレーブ内のガスを放出して常圧に戻した後、反応溶液を回収した。反応溶液をガスクロマトグラフィーで分析し、ロータリーエバポレーター(東京理化器械社製)で反応溶液を濃縮して得られた固体を高速液体クロマトグラフィー(HPLC)および1H−NMR(400MHz、日本電子社製)により分析した。結果を表1に示した。なお、ε−カプロラクタムの定量分析は高速液体クロマトグラフィー(HPLC)で、副産物の定量分析はガスクロマトグラフィーで行い、アジポアミドの定量分析は1H−NMRで行った。
