項5
前記スルホン化合物が、スルホラン、3-メチルスルホラン、エチルメチルスルホン及びエチルイソプロピルスルホンからなる群より選択される少なくとも1種である、項3に記載の製造方法。
工程Aにおいて使用するアルカンスルホン酸化合物は、下記一般式(1)で表される化合物である。
工程Aでは、少なくとも1種の錯体を使用する。斯かる錯体は、ルイス塩基及び三酸化硫黄(SO3)を有する。工程Aで使用する錯体は、例えば、ルイス塩基と三酸化硫黄とが配位結合した構造を有し得る。この場合、例えば、ルイス塩基1分子と、三酸化硫黄1分子とで錯体が形成される。あるいは、三酸化硫黄1分子に2分子以上のルイス塩基が配位することもあり、この場合、2分子以上のルイス塩基はすべて異なる種類であっても、一部又は全部が同一種であってもよい。
工程Aでは、前記少なくとも1種のアルカンスルホン酸化合物と、前記少なくとも1種の錯体とを反応する。
攪拌機、冷却管、温度計及び滴下ロートを備えた四つ口フラスコに、ルイス塩基としてスルホラン36.1g(0.30モル)を仕込み、そこへ三酸化硫黄12.0g(0.15モル)を30分かけて滴下して混合液を得た後、該混合液を60℃まで昇温し、この温度で混合液を30分間攪拌した。得られた反応液を20℃まで冷却し、そのまま1時間攪拌した後、析出した白色結晶を乾燥窒素雰囲気で濾別し、その後、ジクロロメタンで洗浄した。得られたウェット体を乾燥窒素雰囲気で乾燥させることにより、ルイス塩基及び三酸化硫黄からなる錯体20.1g(0.10モル)を得た。この錯体がスルホラン-三酸化硫黄錯体であることは、下記に示す1H-NMR分析結果から判断できた。
1H-NMR(400MHz、CDCl3)δ(ppm):2.28(4H),3.17(4H)
なお、比較として遊離のスルホランの1H-NMR分析の結果は、
1H-NMR(400MHz、CDCl3)δ(ppm):2.23(4H),3.04(4H)であった。
攪拌機、冷却管、温度計及び滴下ロートを備えた四つ口フラスコに、原料Aとして、製造例1で得られたスルホラン-三酸化硫黄錯体40.1g(0.20モル)及びメタンスルホン酸19.2g(0.20モル)を仕込んだ。フラスコ内の原料Aを攪拌しつつ、150℃まで昇温し、この温度で反応を5時間続けることで反応液を得た。得られた反応液を適量採取してイオンクロマトグラフィー分析を行い、この分析で得られたピークの面積値に基づき、仕込みのメタンスルホン酸を基準として生成物である式(4)で表されるメタンジスルホン酸(R1及びR2が水素原子であり、nが1である化合物)の生成収率を算出した。その結果、得られたメタンジスルホン酸の生成収率は75mol%であった。
原料Aの調製において、スルホラン-三酸化硫黄錯体の使用量を80.1g(0.40モル)に変更したこと以外は実施例1と同様の手順によって式(4)で表されるメタンジスルホン酸(R1及びR2が水素原子であり、nが1である化合物)を製造し、生成収率を算出した。その結果、得られたメタンジスルホン酸の生成収率は82mol%であった。
攪拌機、冷却管、温度計及び滴下ロートを備えた四つ口フラスコに、メタンスルホン酸19.2g(0.20モル)及び三酸化硫黄16.0g(0.20モル)からなる原料を仕込んだ。フラスコ内の原料を攪拌しつつ、150℃まで昇温し、この温度で反応を5時間続けることで反応液を得た。得られた反応液を適量採取してイオンクロマトグラフィー分析を行い、この分析で得られたピークの面積値に基づき、仕込みのメタンスルホン酸を基準として生成物である式(4)で表されるメタンジスルホン酸(R1及びR2が水素原子であり、nが1である化合物)の生成収率を算出した。その結果、得られたメタンジスルホン酸の生成収率は40mol%であった。
