| 摘 要： | 采用1102型气相色谱仪和紫外分光光度计分别对自制歧化松香产品的组成、含量分析。气相色谱法能够准确、全面地对歧化松香产品进行松香树脂酸含量的分析测定。按照ZB B 72002-1984《歧化松香》,使用两台不同型号的紫外分光光度计对产品中的枞酸和脱氢枞酸含量进行分析测定,选择狭缝宽度为0.1 nm,紫外分光光度法对枞酸含量在0.05%～4.88%、脱氢枞酸含量在41.1%～50.9%之间的歧化松香产品分析较准确。

| Abstract: | Prepared disproportionated rosin was analyzed by 1102 GC and UV spectrophotometer.It shows that the resin acids in disproportionated rosin can be determinated precisely and completely by GC.According to Chinese disproportionated rosin product standard ZB B 72002-1984,abietic acid and dehydroabietic acid in products were determinated by two different UV spectrophotometers.The width of slot is 0.1nm.Abietic acid and dehydroabietic acid can be determinated correctly in some concentration range by UV spectrophotometer,the range of abietic acid is from 0.05%-4.88%,and the dehydroabietic acid is from 41.1%-50.9%. |
