摘　　要：为了制备高含量二氢枞酸的氢化松香,以歧化松香为原料,200#溶剂油为溶剂,Pd/C为催化剂,在CQF-0.1L高压釜中进行加氢反应研究,考察了催化剂用量、反应温度、反应压力、搅拌转速和反应时间对加氢反应产物中二氢枞酸含量的影响。结果表明,影响歧化松香加氢反应产物中二氢枞酸含量的因素按显著水平依次为:催化剂用量>反应温度>反应压力>反应时间>搅拌转速;最佳反应条件:催化剂用量为0.15%,溶剂用量占50%,反应温度为250℃,反应压力为7 MPa,反应时间为80 min,搅拌转速为500 r/min,所得反应产物中二氢枞酸的含量为90.46%。In order to prepare high content of dihydroabietic acid of hydrogenated rosin,the hydrogenation reaction was studied in CQF- 0. 1 agitated autoclave using disproportionated rosin as raw material,200#solvent oil as solvent,and Pd /C as catalys. The effects of the amount of Pd /C catalyst,reaction temperature,reaction pressure,rotational speed and reaction time on dihydroabietic acid content obtained in the hydrogenation reaction were investigated. The results showed that the influence extent of these factors was in following order： the amount of Pd /C catalyst reaction temperature reaction pressure reaction time rotational speed. The optimum reaction conditions were as follow： catalyst content 0. 15%,solvent content 50%,reaction temperature 250 ℃,reaction pressure 7 MPa,reaction time 80 min and agitating speed 500 r /min. The dihydroabietic acid content in the hydrogenation reaction product was 90. 46%.
