有機アルカノールアミン化合物を添加せずに、エチルイソプロピルスルホン250mLのみを用いて熱安定試験1および2を行った。用いたエチルイソプロピルスルホンの臭い、熱安定性試験1および2の結果、並びに、熱安定性試験1および2を行った後の30℃におけるスルフォランの外観を表1に示す。
実施例1~9、比較例2~6で得られたスルフォラン類組成物、比較例1のスルフォラン、比較例6のスルホンの全量をそれぞれ500mLのフラスコに入れた。フラスコ内の試料に、窒素ガスを83mL/minの流速で通気し、吹き抜けたガスを二酸化硫黄の吸収液として、3%過酸化水素水100mLを含むガス吸引瓶に導入しながら、フラスコ内の試料が約20分間で180±2℃に加熱されるようにフラスコを加熱し、試料温度を180±2℃に保ちながら、窒素ガスを83mL/minの流速で1時間通気した。その後、窒素ガスを40mL/minの流速で通気しながら、温度が100℃になるまで放冷した。放冷後、吸収瓶を取り外し、吸収液中の二酸化硫黄をイオンクロマトグラフィーにより定量した。
実施例1~9、比較例2~6で得られたスルフォラン類組成物、比較例1のスルフォラン、比較例6のスルホンの全量をそれぞれ500mLのフラスコに入れた。オイルバスを加熱して温度を180±2℃まで昇温し、そこにフラスコを浸した。1時間後、フラスコ内の試料中の二酸化硫黄をイオンクロマトグラフィーにより定量した。
蒸留水100mLを入れた300mLの共栓付きマイヤーフラスコにそれぞれ実施例1~9、比較例2~5で得られたスルフォラン類組成物、比較例1のスルフォラン、比較例6のエチルイソプロピルスルホンを1滴加えて、5分攪拌し、1時間静置した。
ついで5人のパネラー(官能試験者)に300mLの共栓付きマイヤーフラスコ中の臭気を、規定基準の「6段階臭気強度表示法」に準じて下記の基準により判定してもらい、その平均値で評価した。結果を表1に示す。
5:強烈な臭い
4:強い臭い
3:楽に認識できる臭い
2:何の臭いか分かる弱い臭い
1:やっと感知できる臭い
0:無臭
実施例2で得られたスルフォラン類組成物について、熱安定性試験1および2を実施後、その溶液を単蒸留し、それらの全量を混合してスルフォラン類組成物を得た。得られたスルフォラン類組成物の全量を500mLのフラスコに入れ、さらに熱安定性試験1および2を行った。結果を表2に示す。
参考例1で得られたスルフォラン類組成物について、熱安定性試験1および2を実施後、それぞれ、その溶液を単蒸留し、それらの全量を混合してスルフォラン類組成物を得た。得られたスルフォラン類組成物の全量を500mLのフラスコに入れ、さらに熱安定性試験1および2を行った。結果を表2に示す。
