環状アセタールに直結する置換基Rはその構造に歪を与えるため、メチル基、エチル基、プロピル基等が好ましい。また市場からの原料の入手のしやすさからエチル基となるものが好ましい。ただし、本構造については相当するアルデヒドとホルムアルデヒド(もしくはその合成等価体)との反応により、容易に合成できるため、必要に応じて合成可能である(米国特許第3097245号公報)。

過酸化水素水によるエポキシ化の手法においては種々の手法が適応できるが、具体的には、特開昭59-108793号公報、特開昭62-234550号公報、特開平5-213919号公報、特開平11-349579号公報、特公平1―33471号公報、特開2001-17864号公報、特公平3-57102号公報等に挙げられるような手法が適応できる。
まず、本発明のジオレフィン化合物、ポリ酸類及び4級アンモニウム塩を有機物と過酸化水素水との二層で反応を行う。
ポリ酸類に含まれる具体的なポリ酸及びポリ酸塩としては、タングステン酸、12-タングスト燐酸、12-タングストホウ酸、18-タングスト燐酸及び12-タングストケイ酸等から選ばれるタングステン系の酸、モリブデン酸及びリンモリブデン酸等から選ばれるモリブデン系の酸、ならびにそれらの塩等が挙げられる。
これらの塩のカウンターカチオンとしては、アンモニウムイオン、アルカリ土類金属イオン、アルカリ金属イオン等が挙げられる。
具体的にはカルシウムイオンマグネシウムイオン等のアルカリ土類金属イオン、ナトリウム、カリウム、セシウム等のアルカリ金属イオン等が挙げられるがこれらに限定されない。特に好ましいカウンターカチオンとしては、ナトリウムイオン、カリウムイオン、カルシウムイオン、アンモニウムイオンである。
具体的にはトリデカニルメチルアンモニウム塩、ジラウリルジメチルアンモニウム塩、トリオクチルメチルアンモニウム塩、トリアルキルメチル(アルキル基がオクチル基である化合物とデカニル基である化合物の混合タイプ)アンモニウム塩、トリヘキサデシルメチルアンモニウム塩、トリメチルステアリルアンモニウム塩、テトラペンチルアンモニウム塩、セチルトリメチルアンモニウム塩、ベンジルトリブチルアンモニウム塩、ジセチルジメチルアンモニウム塩、トリセチルメチルアンモニウム塩、ジ硬化牛脂アルキルジメチルアンモニウム塩等が挙げられるがこれらに限定されない。特に炭素数が25~100の物が好ましい。
またこれら塩のアニオン種に特に限定はなく、具体的にはハロゲン化物イオン、硝酸イオン、硫酸イオン、硫酸水素イオン、アセテートイオン、炭酸イオン、等が挙げられるが、これらに限定されない。
炭素数が100を上回ると疎水性が強くなりすぎて、4級アンモニウム塩の有機層への溶解性が悪くなる場合がある。炭素数が10未満であると親水性が強くなり、同様に4級アンモニウム塩の有機層への相溶性が悪くなり、好ましくない。
4級アンモニウム塩の使用量は使用するタングステン酸類の価数倍の0.01~0.8倍当量、あるいは1.1~10倍当量が好ましい。より好ましくは0.05~0.7倍当量、あるいは1.2~6.0倍当量であり、さらに好ましくは0.05~0.5倍当量、あるいは1.3~4.5倍当量である。
例えば、タングステン酸であればH2WO4で2価であるので、タングステン酸1モルに対し、4級アンモニウムのカルボン酸塩は0.02~1.6モル、もしくは2.2~20モルの範囲が好ましい。またタングストリン酸であれば3価であるので、同様に0.03~2.4モル、もしくは3.3~30モル、ケイタングステン酸であれば4価であるので0.04~3.2モル、もしくは4.4~40モルが好ましい。
特に本発明においては触媒であるタングステン酸類を溶解した際に、pH5~9の間になるように調整されることが好ましい。
緩衝液の使用方法は、例えば好ましい緩衝液である燐酸-燐酸塩水溶液の場合は過酸化水素に対し、0.1~10モル当量の燐酸(あるいはリン酸二水素ナトリウム等の燐酸塩)を使用し、塩基性化合物(たとえば水酸化ナトリウム、水酸化カリウム、炭酸ナトリウム、炭酸水素ナトリウム、炭酸カリウム等)でpH調整を行うという方法が挙げられる。ここでpHは過酸化水素を添加した際に前述のpHになるように添加することが好ましい。また、リン酸二水素ナトリウム又はリン酸水素二ナトリウム等を用いて調整することも可能である。好ましい燐酸塩の濃度は0.1~60重量%、好ましくは5~45重量%である。
また、本反応においては緩衝液を使用せず、pH調整無しに、リン酸水素二ナトリウム、リン酸二水素ナトリウム、リン酸ナトリウムあるいはトリポリ燐酸ナトリウム等(またはその水和物)の燐酸塩を直接添加しても構わない。工程の簡略化、という意味合いではpH調整のわずらわしさが無く、直接の添加が特に好ましい。この場合の燐酸塩の使用量は、過酸化水素に対し、通常0.1~5モル%当量、好ましくは0.2~4モル%当量、より好ましくは、0.3~3モル%当量である。この際、過酸化水素に対し、5モル%当量を超えるとpH調整が必要となり、0.1モル%当量未満の場合、生成したエポキシ樹脂の加水分解物が進行しやすくなる、あるいは反応が遅くなる等の弊害が生じる。
その使用量としては水、あるいは有機溶剤(例えば、トルエン、キシレン等の芳香族炭化水素、メチルイソブチルケトン、メチルエチルケトン等のケトン類、シクロヘキサン、ヘプタン、オクタン等の炭化水素、メタノール、エタノール、イソプロピルアルコール等のアルコール類等の各種溶剤)に溶解するものであれば、その使用量は過剰分の過酸化水素のモル数に対し、通常0.01~20倍モル、より好ましくは0.05~10倍モル、さらに好ましくは0.05~3倍モルである。これらは水、あるいは前述の有機溶剤の溶液として添加しても単体で添加しても構わない。
水や有機溶剤に溶解しない固体塩基を使用する場合、系中に残存する過酸化水素の量に対し、重量比で1~1000倍の量を使用することが好ましい。より好ましくは10~500倍、さらに好ましくは10~300倍である。水や有機溶剤に溶解しない固体塩基を使用する場合は、後に記載する水層と有機層の分離の後、処理を行っても構わない。
得られた有機層は必要に応じてイオン交換樹脂や金属酸化物(特に、シリカゲルやアルミナ等が好ましい)、活性炭(中でも特に薬品賦活活性炭が好ましい)、複合金属塩(中でも特に塩基性複合金属塩が好ましい)、粘度鉱物(中でも特にモンモリロナイト等層状粘度鉱物が好ましい)等により、不純物を除去し、さらに水洗及びろ過等を行った後、溶剤を留去し、目的とするエポキシ化合物を得る。場合によってはさらにカラムクロマトグラフィーや蒸留により精製しても構わない。
