摘要: |
本文研究了从五棓子中提取单宁时五棓子粉碎程度、浸取溶剂、温度、时间对浸取率的影响。确定了最佳浸取条件。用磷钼钨杂多酸光度法测定了浸取率和产品纯度。此外,还进一步用红外光谱分析和热分析法对产品作了鉴定。 |

Abstract: |
This paper has studied the effects of the gall particle size,the leaching solvent,temperature and time on the leaching percentage while extracting tannin from Chinese gall; found out the best leaching conditions; examined the leaching percentage and the purity of products by using the phosphomolybdotungstic acid(hetero-poly acid) spectrophotometric method; identifined the products by using the IR spectrometry and thermal analysis. |
