Description
図1 触媒反応ゾーンが配置され、本発明による方法を実施するのに使用する、塔を備えたプラント、
図2 触媒反応ゾーンのセクション、
図3 塔の好ましい態様の塔頂領域、及び
図4 製造された脂肪酸エステルを清浄化するためのプラントの一部
を示す図面に基づいて、以下に説明する。
出発原料A=IPA及びF=PAに対しては、純度がそれぞれ95重量%及び98重量%であることが好ましい。しかしながら、他の値、すなわち、IPAでは88重量%〜100重量%、及びPAでは95重量%〜100重量%の範囲、もまた可能である。予備反応器2は100℃、2バールで運転される。しかしながら、それは、140℃までの温度及び対応する4バールまでのより高い圧力で運転が可能である。通例、異なる量のIPAがライン21と11を通って供給される。IPA(ライン21)のIPA(ライン11)に対する比率は、好ましくは2.5であるが、1〜4の範囲とすることもできる。塔1のヘッド圧は2〜5バールであり、それに対応して反応ゾーン3の温度は、120℃〜140℃である。中間生成物(ライン53)は加熱装置5内で、170〜200℃の温度まで加熱されるが;それを超えて250℃まで加熱することもできる。
イソプロパノールを用いたパルミチン酸のエステル化を、大気圧の塔内で、以下の条件下で連続的に実施した。
反応塔:
内径:50mm.
富化セクション及びストリッピングセクション:Sulzer充填物BX
反応ゾーン:catapak−S/140℃までの温度で安定な、強酸性イオン交換樹脂で充填
供給流:
パルミチン酸(供給1):2.16kg/h−イソプロパノール(供給2):1.44kg/h
生成物流:
塔頂生成物:1.2kg/h−油だめ生成物:2.4kg/h
運転条件:

74.5−水:0.83
例1と同様な構築物を圧力塔において実現した。ここでは予備活性化済みの供給原料を使用したが、これにより予備反応器をシミュレートできる。わずかに過剰な圧力により、約140℃の反応ゾーンの範囲の温度を反応ゾーンにおいて設定した。以下の運転条件により顕著に高い反応転化率が得られた。
供給流:
フィード1:以下の組成(重量%)を持つものを2.3kg/h
パルミチン酸イソプロピル:24.3−イソプロパノール:21.6−
パルミチン酸:52.1−水:2.0
フィード2:イソプロパノール:1.84kg/h
生成物流:
塔頂生成物:1〜43kg/h−油だめ生成物:2.71kg/h
運転条件:
ヘッド圧:5100ミリバール−還流比:0.2
反応ゾーン温度:約140℃−油だめ温度:192℃
油だめ濃度測定値(重量%):
パルミチン酸イソプロピル:64.0−イソプロパノール:7.7−
パルミチン酸:28.3−水:0.06
