Description
ソルビトール粉末(D−ソルビトール、Samyang Genex Inc.製)10,000gを撹拌器付き回分式反応器に入れ、110℃まで昇温して、溶解した。ここに、硫酸(Duksan Chemical社製)100gとメタンスルホン酸(Duksan Chemical社製)42gを投入し、反応器の温度を約140℃まで昇温した。約30mmHgの減圧条件下で脱水反応を行い、無水糖アルコールに転換させた。脱水反応完了後、反応混合物の温度を110℃まで冷却し、50%水酸化ナトリウム溶液(Samjeon Pure Chemical社製)約300gを添加して、反応生成液を中和した。中和した生成液の温度を100℃にした後、40mmHg以下の減圧条件下で1時間以上濃縮し、生成液内に存在する水分及び低沸点物質を除去した。中和及び水分除去の完了後、生成液を分析した。その結果、ソルビトールの転換率は74%であり、生成液内のソルビタン及びソルビタン異性体の含量は1重量%であり、その他の高分子の含量は15%であった。
転換率=[生成された無水糖アルコールのモル/投入したヘキシトール(ソルビトール)モル]×100
蒸留収率=[蒸留物内無水糖アルコールの重量%/転換生成液内無水糖アルコールの重量%]×100
実施例1で得られた中和及び水分除去が完了した転換生成液を外部コンデンサ型ワイプドフィルム蒸発器に投入し、蒸留温度185℃、蒸発器内部圧力1.3mmHgの条件下で1段階蒸留を行った。次いで、1段階蒸留の生成蒸留物を図1に示す構造の内部コンデンサ型短行程蒸発器に投入し、蒸留温度100℃、蒸発器内部圧力0.01mmHgの条件下で2段階蒸留を行った。このとき、真空ラインに加えて蒸留残留物排出ラインの真空形成用分岐ラインにも真空ポンプを連結し、蒸留を行った。
実施例1で得られた中和及び水分除去が完了した転換生成液を外部コンデンサ型ワイプドフィルム蒸発器に投入し、蒸留温度185℃、蒸発器内部圧力1.3mmHgの条件下で1段階蒸留を実施した。次いで、1段階蒸留の生成蒸留物を図1に示す構造の内部コンデンサ型短行程蒸発器に投入し、蒸留温度170℃、蒸発器内部圧力5.0mmHgの条件下で2段階蒸留を行った。このとき、真空ラインに加えて蒸留残留物排出ラインの真空形成用分岐ラインにも真空ポンプを連結し、蒸留を行った。
