| Abstract: | Thermal stability of hydrogenated rosin was studied under the conditions of heating at 200 ℃ for 2 h.Thermal stability of hydrogenated rosin was poor if iron content>21.5 mg/kg and unsaponifiable matter content>7.1%.Although hydrogenated rosin could be made from rosin below grade WG,its thermal stability was poor.Hydrogenated rosin of high thermal stability was made by method of disproportionrefinementhydrogenation. |

| Keywords: | hydrogenated rosin thermal stability color |
