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.

我们开发了纳米介质，这是能够产生meso-四苯基卟啉从苯甲醛和吡咯在相对高度浓缩的条件下（0.1摩尔/升）。在四烷基铵盐和LiOH存在下，以Si（OEt）_4和Al（O^iPr）_3为原料，制备了含有少量锂离子的纳米多孔硅铝酸盐，这种新型固体酸催化剂对卟啉的合成具有比传统的均相酸催化剂（如BF_3）高得多的催化活性。
