Abstract

一种改性环糊精的制备方法,属于低聚糖制备技术领域。其是向反应瓶中加入乙醇和环糊精,一定温度下搅拌0.5h,然后在此温度下加入聚乙二醇单环己醚,并维持此温度搅拌1‑24h,最后蒸去乙醇,得到改性环糊精。由于步骤少,工艺简单,因而设备简单并降低成本;由于聚乙二醇单环己醚具有既亲水基团又有亲油基团,并且与环糊精有良好的分子间亲合力,因而制备的聚乙二醇单环己醚改性环糊精比原环糊精有更高的水溶性。

Description

改性环糊精的制备方法
技术领域
本发明属于低聚糖制备技术领域,具体涉及一种改性环糊精的制备方法。
背景技术
环糊精(Cyclodextrin,简称CD)是直链淀粉在由芽孢杆菌产生的环糊精葡萄糖基转移酶作用下发酵生成的一系列环状低聚糖的总称,通常含有6~12个D-吡喃葡萄糖单元。其中研究得较多并且具有重要实际意义的是含有6、7、8个葡萄糖单元的分子,分别称为α-环糊精、β-环糊精和γ-环糊精。可与许多无机、有机分子形成主客体包合物,并能改变被包合物的化学和物理性质,具有保护、稳定、增溶客体分子和选择性定向分子的特性,因而在食品、环 境、医药、化学检测等方面都有着重要的应用。由于环糊精水溶性较差,因而限制了其在工业领域的进一步应用。
水溶性环糊精主要应用于医药、食品领域,其改性水性树脂方面,特别没有涉及在水性聚氨酯领域的应用。随着人们环保意识以及环保法规的增强,环境友好的水性聚氨酯的研究、开发日益受到重视。水溶性环糊精能增强难溶药物在水中的溶解度,提高难溶药物的稳定性和生物利用度。
目前对于提高环糊精水溶性的方法主要是通过化学方法和酶工程法,由于化学法和酶工程法对环糊精水溶性改性工艺流程复杂,成本较高,而物理改性方法简单,成本较低,易实施,因此可以利用物理法对环糊精进行改性,得到新型环糊精体系。李媛等利用超声的方法将α-环糊精穿入肉桂酸改性的PEG分子链形成包含复合物,提高了环糊精的亲水性,作为新型的纳米药物载体,用于药物控制释放。CN103642190A提到用聚乙二醇改性环糊精,根据其制备方法制得的改性环糊精其水溶性并没有明显改善,因此,寻找一种能明显提高环糊精溶解性的方法很有现实意义。
发明内容
本发明的任务在于提供一种改性环糊精的制备方法,使用该方法制备的改性环糊精比已有技术中的环糊精具有更高的水溶性,并且设备简单有助于简化工艺、降低成本。
本发明的任务是这样来完成的,一种改性环糊精的制备方法,其是向反应瓶中加入乙醇和环糊精,一定温度下搅拌0.5h,然后在此温度下加入聚乙二醇单环己醚,并维持此温度搅拌1-24h,最后蒸去乙醇,得到改性环糊精。
在本发明的一个具体的实施例中,所述的环糊精与乙醇的质量比为1:1-5;所述的环糊精与聚乙二醇单环己醚的摩尔比为1:1-3。
在本发明的另一个具体的实施例中,所述的环糊精为β-环糊精或γ-环糊精。
在本发明的又一个具体的实施例中,所述的聚乙二醇单环己醚的分子量为300-1500。
在本发明的再一个具体的实施例中,所述的一定温度为10-80℃。
本发明提供的技术方案相对于已有技术的技术效果之一,由于步骤少,工艺简单,因而设备简单并降低成本;之二,由于聚乙二醇单环己醚具有既亲水基团又有亲油基团,并且与环糊精有良好的分子间亲合力,因而制备的聚乙二醇单环己醚改性环糊精比原环糊精有更高的水溶性。
具体实施方式
下面结合具体实施例,进一步阐述本发明。下面这些实施例只是用于对本发明的进一步说明,因而不能理解为限制本发明的范围。
实施例1:
向反应瓶中加入乙醇1135g和β-环糊精1mol(1135g),10℃下搅拌0.5h,然后在此温度下加入分子量为1500的聚乙二醇单环己醚1mol,并维持此温度搅拌24h。最后蒸去乙醇即得到改性环糊精。
实施例2:
向反应瓶中加入乙醇3891g和γ-环糊精1mol(1297g),60℃下搅拌0.5h,然后在此温度下加入分子量为1000的聚乙二醇单环己醚3mol,并维持此温度搅拌10h。最后蒸去乙醇即得到改性环糊精。
实施例3:
向反应瓶中加入乙醇5675g和β-环糊精1mol(1135g),80℃下搅拌0.5h,然后在此温度下加入分子量为300的聚乙二醇单环己醚2mol,并维持此温度搅拌1h。最后蒸去乙醇即得到改性环糊精。
实施例4:
向反应瓶中加入乙醇5000g和β-环糊精1mol(1135g),45℃下搅拌0.5h,然后在此温度下加入分子量为750的聚乙二醇单环己醚1.8mol,并维持此温度搅拌8h。最后蒸去乙醇即得到改性环糊精。
