室温离子液体BPBF4为溶剂合成六羧基双核酞菁钴

Synthesis of Hexacarboxy biphtalocyanine Cobalt Using BPBF4 as Solven

摘要:

本文以偏酐、均酐、尿素、六水合氯化钴为原料，钼酸铵为催化剂，室温离子液体BPBF4为溶剂合成了中间产物六酰胺基双核酞菁钴，采用正交试验对影响六酰胺基双核酞菁钴收率的主要因素进行了考察，结果表明， V(BPBF4)= 60mL，n（均酐）：n（尿素）=50，T=200℃，t=2h为最佳条件。将中间产物进一步在碱性条件下水解得六羧基双核酞菁钴，并通过IR、UV-Vis、1HNMR、元素分析等进行了表征。与常规液相法相比，使用室温离子液体为溶剂，不仅避免了使用传统有机溶剂所造成的环境污染，且重复利用性好。

Abstract:

CoBPcN6 was synthesized respectively using trimellitic anhydride, pyromellitic dianhydride, urea, CoCl2 •6H2O as starting materials and ammonium molybdate as catalyst in BPBF4 , and then hydrolysed to CoBPcC6 under alkaline conditions. The products were characterized by IR and UV-Vis、1HNMR and elemental analysis etc. . The main factors which affect the yield of CoBPcN6 were investigated by Orthogonal test. The results indicate that the optimal conditions are as follows: V (BPBF4) = 60mL, n (PMDA): n (urea) = 50, T = 200 ℃, t = 2h . Compared with conventional liquid phase, it not only avoids environmental pollution caused by the use of conventional organic solvents, but also can be used repeatedly without reducing the activity.
