摘要: <正>研究了歧化松香胺席夫碱一铜配合物的合成及其对漆酚氧化聚合反应的催化性能。用歧化松香胺和水杨醛反应,生成席夫碱,再与醋酸铜反应,制备席夫碱一铜配合物。讨论了该配合物作为催化剂,催化漆酚氧化聚合反应时,催化剂浓度、时间、底物浓度以及温度对漆酚氧化聚合反应的影响。结果表明,氧化聚合反应的理想条件是以乙醇为溶剂,加入3%歧化松香胺席夫碱一铜配合物催化剂,漆酚浓度为0.0688g/mL,在30℃下反应36h后,漆酚聚合物的沉淀得率为51.3%。

Abstract: Based on the different levels of basal manure(800 g per plant, 1 200 g per plant, 1 600 g per plant, 2 000 g per plant, 2 200 g per plant), the effects of basal manure on growth, leaf mineral elements and chlorophyll contents in Acacia crassicarpa were studied. The results showed that the 1 600 g per plant treatment was most effective. With this treatment,the growth and leaf mineral elements and chlorophyll contents of A. crassicarpa all increased more greatly compared with the other treatments,and the analysis of variance shows that the differences between this treatment and others were significant.
