THE DEVELOPMENT OF NANO MEDIA FOR HIGHLY EFFICIENT SYNTHESIS OF PORPHYRINS

我们开发的纳米介质能够在相对较高的浓度(0.1mol/L)下由苯甲醛和吡咯合成四苯基卟啉。以Si(OEt)4和Al(O^IPr)3为原料，在四烷基铵盐和LiOH存在下，制备了含少量锂离子的纳米多孔铝硅酸盐催化剂。新型固体酸催化剂对合成卟啉的催化活性远高于传统的BF3等均相酸催化剂。

We developed nano media which is able to produce meso-tetraphenylporphyrin from benzaldehyde and pyrrole under relatively highly concentrated conditions (0.1 mol/l). We prepared nanoporous aluminosilicate which contains a small amount of lithium cations by use of Si(OEt)_4 and Al(O^iPr)_3 in the presence of tetraalkylammonium salts and LiOH.The new solid acid catalyst shows much higher catalytic activity for porphyrin synthesis than traditional homogeneous acid catalysts such as BF_3.
