Description
ジメチロールブタナール(DMB)を金属触媒及びアルコール溶媒下で水素化反応させてトリメチロールプロパン(TMP)を製造するステップを含み、
上記水素化反応の時、ジメチロールブタナールを基準にアルコール溶媒の重量比が2ないし10であるトリメチロールプロパンの製造方法を提供する。
収率(%)=ΔTMP/反応物DMB×100
DMB転換率(%)=100×(1−生成物DMB/反応物DMB)
選択度(%)=ΔTMP/ΔDMB×100=収率×100/転換率
図1によれば、ジメチロールブタナールは配管11を通じて、アルコール溶媒は配管12を通じてそれぞれ反応原料1に投入される。このとき、アルコール溶媒は、炭素数2ないし10のアルコール溶媒であってもよく、好ましくは炭素数8のアルコール溶媒であってもよく、より好ましくは2−エチルヘキサノールであってもよい。上記ジメチロールブタナールは、アルドール縮合反応の後、一連の分離過程を経て得ることができる。上記一連の分離過程は、抽出であってもよい。
図2によれば、貯蔵槽7には、未反応のDMBを含む生成物の一部が少量流入することができる。この場合、未反応のDMBの転換及び水素化反応の反応熱を制御するために、貯蔵槽7にある未反応のDMBを含む生成物の一部が配管19を通じて反応器4に流入して、再循環されることができる。
<製造例1>
10Lのジャケット型(jacket type)反応器において、FA/n−BAL=4のモル比で反応したアルドール縮合反応生成物から、抽出を通じてジメチロールブタナール(DMB)を製造した。
製造例1で得たDMBに2−エチルヘキサノール(2−EH)を添加して水素化原料を調製した。
その後、銅系金属触媒が充填されているL/D(反応区域の高さ(L)を直径(D)で割った値)が30であるFBR(Fixed Bed Reactor)に調製された原料を投入して、水素化反応によってTMPを製造した。
このとき、DMBを基準に2−EHの重量比(2−EH/DMB)は4だった。水素化反応時に添加される水素のモル数は、H2/DMB(mol/mol)=1.5とし、 WHSV(Weight Hourly Space Velocity)=0.3h-1に設定した。反応器の入口と出口にはアルミナボールが中間の触媒層を支持しており、12個の温度センサーが一定の間隔で差し込まれて温度プロファイル(profile)を示した。触媒層の入口温度を反応温度として120℃で実験し、反応圧力は30bar(3MPa)に設定した。
実施例1において、DMBを基準に2−EHの重量比(2−EH/DMB)は6であることを除き、実施例1と同一の方法でTMPを製造した。
実施例1において、DMBを基準に2−EHの重量比(2−EH/DMB)は10であることを除き、実施例1と同一の方法でTMPを製造した。
実施例1において、DMBを基準に2−EHの重量比(2−EH/DMB)は12であることを除き、実施例1と同一の方法でTMPを製造した。
実施例1において、2−エチルヘキサノールの代わりに1−ヘキサノール(1−hexanol)を使用し、DMBを基準に1−ヘキサノールの重量比(1−ヘキサノール/DMB)は4であることを除き、実施例1と同一の方法でTMPを製造した。
DMB転換率(%)=100×(1−生成物DMB/反応物DMB)
TMP選択度(%)=ΔTMP/ΔDMB×100=収率×100/転換率
実施例1において、DMBを基準に2−EHの重量比(2−EH/DMB)は1であることを除き、実施例1と同一の方法でTMPを製造した。
