摘　　要：高酸值松香在高温高压条件下进行加氢反应,使分子内碳-碳双键饱和,得到稳定的工业化产品.以Pd/C为催化剂,研究了不同加氢工艺条件对产物性能的影响,得到最佳加氢反应条件:加氢反应压力5 MPa,反应温度200℃,反应时间2 h,催化剂用量0.3%.采用红外光谱法对加氢前后高酸值松香的结构进行了表征,并通过氧化性实验等方法对加氢效果进行评价.结果表明:在此条件下加氢,产物碳碳双键含量减少,其综合性能特别是高温耐氧化性得到了显著提高.The hydrogenation reaction of high acid rosin can be processed under high temperature and pressure,which can eliminate the intramolecular double carbon bond and obtain stable product.In this paper,using Pd/C catalyst,the effects on product properties were investigated under different conditions of hydrogenation reaction.Based on the experimental data,the optimum reaction conditions were as follows: reaction pressure,5 MPa;reaction temperature,200 ℃;reaction time, 2 h;quantity of catalyst 0.3% of rosin.The s...
