Description
A2工程:吸収後の有機溶媒からのガス混合物の脱離(脱着)
B工程:ガス混合物中の窒素酸化物NOXの含有量を、ガス混合物全量当たり容積比でせいぜい0.5%へ調整
これらの相は、並流、向流又はこれらの組み合わせで吸収器内に送られる。
A2工程:吸収後の有機溶媒中からのガス混合物の脱離
B工程:ガス混合物中の窒素酸化物NOXの含有量を、ガス混合物全量に対して最大0.5容量%に調整
C工程:ガス混合物を少なくとも一つのオレフィンと接触
(b)工程:5〜500barの範囲の圧力下での反応容器内で、反応混合物G(i)と本発明により精製した亜酸化窒素を含むガス混合物とを接触
(c)工程:150〜320℃の範囲の温度まで(b)で得られる混合物を、1〜10℃/minの範囲の速度で加熱
(d)工程:0.1〜48hの範囲の期間で(c)で設定された温度を維持
(bb):本発明により精製した亜酸化窒素を含むガス混合物を0〜320℃の範囲の温度で、5〜500barの範囲の圧力で連続反応器に投入する
(cc):100〜320℃の範囲の温度で5〜500barの範囲の圧力で、この混合物G(i)と本発明により精製されたガス混合物とを連続反応器内で接触させる
(dd):0.1〜48時間の反応混合物の滞留時間で、混合物G(i)と本発明により精製されたガス混合物を連続反応器内で反応させる。
・反応物にかかる圧力の変更。この場合、例えば少なくとも一つのポンプ及び/又は少なくとも一つの圧縮機により加圧することが好ましい。
・少なくとも一つの反応物の計量投入。具体的には、亜酸化窒素及び/又はシクロドデセンを計量投入する。シクロドデセンを投入する場合、それは、新たに加えられたシクロドデセンであってもよく、及び/又は第二ステージで変換されず、生成物流から少なくとも一つの適当な手段により分離され、プロセスにリサイクルされたシクロドデセンであってもよい。
・少なくとも一つの適当な手段による生成シクロドデカノンの除去、例えば、好ましくは少なくとも1回の蒸留工程。
(b)工程:シクロドデカトリエンのシクロドデセンへの部分水素化
(i)工程:アジピン酸プラント及び/又は硝酸プラント及び/又はヒドロキシルアミンプラント及び/又は硝酸プラントからのオフガス流の少なくとも一つ当たり酸素及び/又は窒素酸化物が0〜0.5容量%になるように、亜酸化窒素含有ガス混合物をアジピン酸プラント及び/又はドデカン二酸プラント及び/又はヒドロキシルアミンプラントのオフガスに供給
(ii)工程:(b)で得られるシクロデセンと(i)で得られるガス混合物との反応によりシクロドデカノンを製造。
シクロドデセンとシクロドデカンの混合物、シクロドデセンとシクロドデカトリエンの混合物、シクロドデカンとシクロドデカトリエンの混合物、又はシクロドデセンとシクロドデカンとシクロドデカトリエンの混合物が、最初に供給される。該当する混合物中のシクロドデカトリエン含有量は一般的に重要ではないが、連続プロセスでは最大30重量%、より好ましくは最大25重量%、特に好ましく最大20重量%である。
ホウ酸存在下でのシクロドデカンのシクロドデシルボレートへの空気酸化、
このボレートのシクロドデカノールへの加水分解、及び
シクロドデカノールのシクロドデカノンへの脱水素の4工程を含む上述の既存のプロセスと比較してとりわけ注目すべきは、
本発明に係るシクロドデカノンの製造方法では、同一反応物、シクロドデカトリエンから出発して、二段階の反応を省いてシクロドデカノン生成物を製造できる、つまり反応段階の数を半減できるという点である。
実施例1
テトラデカンでの一段吸収
表1.1に示した組成の反応剤ガス(151mol/h)を25絶対気圧まで圧縮し、30℃に冷却した後、吸収カラム(Φ=8cm、高さ=400cm、充填材=クーニロンボパック)に供給した。塔頂より、工業用テトラデカン(脱離段階からの)を96kg/hの速度で供給した。塔頂から排出されるオフガスは廃棄した。吸収塔の塔底の吸収溶媒は、フラッシュ容器(Φ=20cm、高さ=50cm、30℃で運転)中で1絶対気圧まで減圧した。この溶媒は、吸収段階までポンプで返送した。吸収された生成物ガス(12.9mol/h)は分析後、廃棄した。その組成も、表1.1に示した。
テトラデカンによる二段吸収
第1の脱離段階から排出される表1.2に示した組成の生成物ガス混合物(12.9mol/h)を25絶対気圧まで圧縮し、30℃まで冷却し、第二吸収カラム(Φ=5cm、高さ=400cm、充填材=クーニロンボパック)の最下段に供給したこと以外は同様にして、実施例1の操作を繰り返した。塔頂より工業用テトラデカン(第二脱離段階より)を12kg/hの速度で供給した。塔頂より排出される第二吸収塔のオフガスは廃棄した。第二吸収塔塔底の吸収溶媒は、第二フラッシュ容器(Φ=10cm、高さ=40cm、30℃で運転)にて、1絶対気圧まで減圧した。この溶媒はポンプにて第二の吸収段階に返送した。次いで、第二塔からの脱着された生成物ガス(6.8mol/h)を分析した。この組成も、表1.2に示した。
テトラデカンでの二段吸収と、続くスクラビング
第二の脱離段階から排出される表1.3に記載の組成を持つ生成物ガス(6.8mol/h)をスクラビングカラム(Φ:5cm、高さ:300cm、充填材:10mmポールリング)に供した以外は、実施例2を繰り返した。塔頂よりNaHCO3水溶液(濃度:40g/kg)を20kg/hの速度で投入した。次いで、スクラビングカラム塔頂のガスを分析した。この組成も、表1.3に示す。
テトラデカンでの二段吸収と、続くスクラビング及び液化
