挤压机作为反应器转化淀粉的研究——羟乙基葡萄糖苷的合成及其分离

摘要:

本文探索采用挤压机,特别是单螺杆挤压机作为反应器转化淀粉合成羟乙基葡萄糖苷的可能性,结果表明:在适宜的参数条件下,取螺杆挤压机可将90%的淀粉转化为葡糖苷,而采用单螺杆挤压机,转化率达75%;同时,对淀粉在酸催化下转化为乙二醇葡糖苷的过程、产物的构成进行了初步的探讨,并提出了挤出物分离的设想。

Abstract:

The possibility of the conversion of corn starches to hydroxyhyl glucosides by using extruders, especially single-screw extruders, as reactors is investigated in this paper. The results are revealed that under the proper conditions, 90% of the starch is c
