在氢常压下，１４０～２００°Ｃ间系统考察了催化剂和反应条件对松香常压加氢的影响．首次在氢常压下，在钯和非钯催化剂上分别得到了合符工业要求的氢化松香（枞酸＜２％，去氢枞酸＜１５％）．
Hydrogen atmospheric pressure, 140 ~ 200 ° C between the system investigated the catalyst and the reaction conditions of rosin atmospheric hydrogenation. Hydrogenated rosins (<2% abietic acid, dehydroabietic acid <15%) were obtained for the first time under hydrogen atmospheric pressure on palladium and non-palladium catalysts, respectively.
