D-葡萄糖醛酸内酯制备
1、 由葡萄糖醛酸(见前条)内酯化制得:淀粉用硝酸氧化再经水解得到的葡萄糖醛酸浓缩液,与冰醋酸混合,于60-65℃(5.32-14.6kPa)减压内酯化,同时回收乙酸,反就物冷却放置6-8d,即结晶出葡萄糖醛酸内酯。用乙醇水溶解液重结晶,尖性炭脱色精制即得成品。
2、 氧化 按淀粉(m):硝酸(67%±0.5%,V):水(V)=1:1.5:8.5的配料比投料。先将硝酸投入氧化釜内,开动搅拌,加热至60℃。加入淀粉,(全量的2%),在15min内升温至78℃进行引发,保持5min,然后于15min内均匀降温至50-60℃,隔20min加入淀粉,共分两次(全量的30%),最后在47℃±1℃的温度下,隔25min加入淀粉,共分四次(全量的68%)。控制温度使反应平均每小时升温5℃,保持7-8h,温度达到68℃,放料,于料液中加水(全量的12%),通蒸汽加热70-80℃,20min内,驱除NO2,静置后,再加水(全量的88%),得羧基淀粉液。
淀粉[HNO3,淀粉,水]→[47℃±1℃, 7-8h]羟基淀粉液
水解 将羧基淀粉液抽入水解罐中,蒸汽加热至100℃有黄烟和水蒸气冒出。然后密闭,内压升高至245.25kPa(2.5kgf/cm2),温度为140-142℃,水解2h,得水解液,即得葡萄糖醛酸溶液。
羟基淀粉液[245kPa]→[140-142℃, 2h]水解液(葡萄糖醛酸)
内酯化 将上述水解液通过122型弱酸性阳离子交换树脂进行脱色,脱色液抽入浓缩罐中,在真空度约为93.33 kPa (700mmHg)、50-60℃以下,减压浓缩至34-36°Be时为止。在浓缩液中加入淀粉投料量1.68倍的冰醋酸,置于酯化罐中,在常温下酯化16-24h,放冷至0-5℃结晶,过滤,得葡萄糖醛酸内酯粗品。
水解液[112型树脂,冰HAc]→[16-24h]葡萄糖醛酸内酯粗品
精制 按粗品(m):蒸馏水(V):乙醇(V):活性炭(m)=1:0.7:0.4:0.01-0.03的比例投料。将粗品和蒸馏水置于精制罐中,加热,不断搅拌,使之全溶,加活性炭脱色,再加乙醇,搅拌均匀,抽滤,滤液冷至0-5℃,放置16h,甩滤,滤饼用无水乙醇洗涤1次,甩干,80℃以下干燥,即得葡萄糖醛酸内酯精品。
葡萄糖醛酸内酯粗品[蒸馏水,乙醇,活性炭]→[0-5℃, 16h]葡萄糖醛酸内酯精品。
