Abstract

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 0.1 nm. 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%.

Key words: disproportionated rosin, GC, UV spectrophotometry, abietic acid, dehydroabietic acid
