本発明の方法において、多糖またはオリゴ糖、好ましくはセルロースの溶媒系の溶液を調製する。多糖またはオリゴ糖の濃度は、様々な範囲に変化させることができる。通常、溶液の総重量に基づいて、0.1〜50重量%の範囲であり、好ましくは0.2〜40重量%の範囲、特に好ましくは0.3〜30重量%、非常に好ましくは0.5〜20重量%の範囲である。
工程Bにおいて、多糖またはオリゴ糖、好ましくはセルロースを、塩素化剤と反応させる。
得られる塩素化セルロースの置換度(DS)は、無水グルコース単位(AGU)当たりの置換ヒドロキシ基の平均数として定義される。
DSは、元素分析において検出された塩素含量から決定される。
例えば、凝固溶媒(塩素化多糖若しくはオリゴ糖について非溶媒)または他の凝固剤、特に塩基若しくは塩基性塩、例えばアンモニアまたはNH4OHを含む溶液を加え、溶媒系から凝固した塩素化多糖若しくはオリゴ糖を分離することにより、この溶液から塩素化多糖またはオリゴ糖を得ることができる。凝固溶媒および反応混合物の混合方法により、異なる塩素化種を得ることができる。例えば、主に単塩素化種は、反応混合物中に凝固溶媒を注入することにより得られる。一方、主に二塩素化種は、凝固溶媒中に反応混合物を注入することにより得られる。
で示すことができる。
セルロース(微結晶性セルロース:Avicel(登録商標)、DP=430)を、イオン性液体、1−ブチル−3−メチルイミダゾリウムクロライド(BMIMCl)に100℃で2時間加熱することにより溶解した。ジオキサンを共溶媒として加えた。反応物を60℃まで冷却し、塩化チオニル(5当量)を加えた。混合物を60℃で2時間攪拌した後、過剰の塩化チオニルを真空下で除去した。その後、混合物を5℃まで冷却し、NH4OHを添加した。沈殿物を濾過し、温水で洗浄し、65℃の真空オーブンで乾燥させた。DP=26、DS=0.8−1.13。乾燥生成物の不溶性の性質のため、分析はCP−MAS NMR(固体NMR)、IR、GPCおよび元素分析により行った。
塩素化セルロースは溶解性が乏しいため、溶液NMRにより分析することはできなかった。IRは、1428cm−1で典型的なCH2−Cl振動を、751cm−1でC−Clバンドを示した。
