| Abstract: | The solid content of 25% of light-colored disproportionated rosin potassium soap was prepared by reacting with solid disproportionated rosin and potassium hydroxide solution. The influence of reaction temperature,saponification time,acid value and decolorising agent on reaction was studied. The results showed that the product was obtained under the condition of reaction temperature at 80℃,reaction time at 75 min,acid value（KOH） at 2. 0 mg /g and dosage of decolorising agent at 0. 2% of disproportionated rosin. The value of ghana color was lowered two grades than product obtained by the current preparation method. |
