摘　　要：将纳米镍催化剂首次应用于树脂酸的歧化反应中。对影响枞酸歧化反应的主要因素,如搅拌转速、催化剂种类及用量、温度和溶剂用量等进行了研究,得出纳米镍催化下枞酸歧化反应的适宜条件为:搅拌转速300 r/min,温度160℃,催化剂用量为枞酸质量的2.0%,溶剂200#溶剂油的质量分数为50%(相对于整个反应体系),反应时间3 h。Nano-Ni was first used as catalyst for disproportionation of resin acid. The main factors affecting disproportionation of abietic acid were investigated, such as stirring rate, the category and quantity of catalysts, temperature, quantity of solvent, etc. The optimum conditions for disproportionation of abietic acid over nano-Ni were determined as follows： stirring rate 300 r/min, reaction temperature 160 ℃ ,dosage of catalyst 2.0 % of abietic acid, 200^# solvent oil 50 % （weight） and reaction time 3 h.
