补充资料:D(-)树胶醛糖
分子式:C5H10O5
分子量:150.13
CAS号:10323-20-3

性质:该品为白色结晶体。熔点为159-160℃,相对密度为1.585(20/4℃),折光率1.585。易溶于水,微溶于醇,不溶于醚、甲醇和丙酮。无气味。

制备方法:由葡萄糖酸钙经降解、氧化而得。将葡萄糖酸钙和水一起加热溶解,加入乙酸钡溶液和硫酸铁溶液混配而成的铁触媒。搅拌升温至95℃,滤去沉淀。清液于40℃加入双氧水氧化,反应温度不超过56℃,反应半小时。反应液变为黑色后静置半小时,降温至40℃,再加入双氧水,按上法氧化。半小时后加入草酸,过滤,除去草酸钙。将滤液真空浓缩至糖浆状,温度不超过48℃。加无水甲醇溶解,放冷结晶,过滤。滤饼用甲醇洗涤,干燥得粗品。粗品用甲醇重结晶,得D(-)-树胶醛糖。另一种制法是将葡萄糖酸钙和葡萄糖酸铁一起用双氧水氧化,反应物过滤后用强酸性苯乙烯系阳离子交换树脂和强碱性季铵I 型阴离子交换树脂处理而得成品。

用途:作医药中间体、生化试剂。
