を含み、
工程(a)を、85℃〜125℃の温度及び20kPa〜80kPaの圧力において行うことを特徴とする、スクロース−6−エステルの合成方法を開示している。
(a)スクロース、極性非プロトン性溶媒、及び有機スズベースのアシル化促進剤を含む第1の反応混合物を形成する工程、
(b)水を除去可能な気体又は溶媒蒸気と、実質的に水を含有しない第2の反応混合物を得るのに十分な温度、圧力、及び滞留時間で、連続向流式で接触させることにより、第1の反応混合物から水を除去する工程、続いて、
(c)第2の反応混合物にカルボン酸無水物を添加して、第3の反応混合物を得ると共に、第3の反応混合物を、スクロース−6−エステルを生成するのに十分な温度及び時間で維持する工程を含む、スクロース−6−エステルの合成方法が提供される。
図1に実験装置を概略的に示す。
1.
1l容のフラスコに、30.08gの砂糖及び200.05gのDMFを充填した。混合物を攪拌し、90℃に加熱して砂糖を溶解した。冷却後、80.20gのDSDA(シクロヘキサン中66.9%))を攪拌しながら添加した。
工程1の混合物を、20プレートOldershawカラム(図2に概略的に示す)の上部に6ml/分(6.24g/分)の速度で連続的に供給した。同時に、シクロヘキサン蒸気をカラムの底部に9.2g/分の速度で供給した。カラム頂からのシクロヘキサン、水、及びDMFを含有する蒸気を凝縮し、凝縮物がカラムに戻らないように回収した。17分間のカラムの操作の後、該プロセスは定常状態であり、液体試料のカラムの底部からの回収を開始した。カラムの底部からの試料は、20分間回収した。この生成物は透明な薄琥珀色であった。カラム滞留時間(反応時間)は4.8分間であると算出された。
カラムの底部からの試料は、12.1g相当の糖を含有すると算出された。(6.24g/分×20分×9.69%の糖=12.1gの糖)。この試料を4.31gの無水酢酸で10℃未満でアセチル化した。10℃未満で2時間後、試料を5.1gの水で急冷した。この時点での試料の重量は107gであった。物質を50mlのシクロヘキサンで抽出して、スズ触媒を除去した。
工程3からの生成物をHPLCによって以下のように分析した:
a.スクロース−6−アセテート=6.15%(正規化84.9%)
b.ジアセテート=1.06%(正規化14.6%)
c.モノアセテート=0.01%(正規化0.14%)
d.スクロース=0.02%(正規化0.28%)
