Description
前記分解反応器70に使用される酸性触媒としては、前記触媒反応器10に使用された通常の酸触媒を用いることができ、例えば、強酸性クレー触媒、シリカ、アルミナ、ゼオライト、酸化モリブデン、強酸性陽イオン交換樹脂などを用いることができ、好ましくは強酸性クレー触媒が用いられるが、これに限定されるものではない。
図2において、触媒反応器10としては、強酸性陽イオン交換樹脂(微孔のあるスルホン化ジビニルベンゼン架橋ポリスチレン樹脂であるアンバーライト触媒)50gを、長さ60cm、内管直径1/2インチ(inch)の二重管型反応器に充填したものを使用し、分解反応器70としては強酸性クレー触媒50gを、長さ60cm、内管直径1/2インチ(inch)の二重管形の分解反応器に充填したものを使用した。それぞれの反応器(10、70)は反応熱を制御できるように、外側管に熱交換水(触媒反応器10の場合)または熱媒体油(分解反応器70の場合)が循環されるようにした。また、抽出塔20、親水性抽出剤ストリッパー30、C4ストリッパー50およびグリコールモノ−tert−ブチルエーテル蒸留カラム60としては15段の蒸留塔を使用した。グリコール化合物1としてはジエチレングリコール(diethylene glycol:DEG)を用い、イソブテン(isobutene:IB)を含むC4炭化水素混合物2としては下記の表1に従う組成を有するC4炭化水素混合物を使用した。前記原料1、2の移送はMFC(Mass Flow Controller)を使用し、下記表2の反応条件により、図1のS1段階ないしS7段階を行い、ジエチレングリコールモノ−tert−ブチルエーテルを製造した。その他、反応条件では、7気圧下でジエチレングリコールモノ−tert−ブチルエーテルを生産し(S1段階)、親油性抽出剤としてはC4炭化水素混合ガスを使用し、親水性抽出剤としては水を使用し(S3段階)、常圧および100℃の条件で蒸留し(S4段階)、3.2kgf/cm2および150℃の条件で蒸留し(S5段階)、0.1バール(bar)および210℃の条件で蒸留し(S6段階)、3気圧下で副産物(ジエチレングリコールジ−tert−ブチルエーテル)を分解した(S7段階)。また、最初の原料投入量(DEG+IBを含むC4炭化水素化合物)は1000gであり、反応物の循環比[再循環されない反応混合物12の量:再循環される反応混合物11の量(重量比)]は1:10であった。分解生成されたイソブテン(IB)およびジエチレングリコール(DEG)の量、未分解の副産物の量および生成されたジエチレングリコールモノ−tert−ブチルエーテル(DETB)の総量を測定して下記表2に示す。
