摘要：
经济的发展使得各种车辆在急剧增加,这一过程引起了燃油的大量使用,燃油中的含硫化合物燃烧便成了硫氧化物,严重污染了环境.为了保护环境,就要降低燃油中的含硫化合物.合成了四氨基酞菁铝配合物,利用元素分析、红外光谱以及紫外—可见光谱对其结构进行了表征,然后以四氨基酞菁铝作为脱硫催化剂,测定了它在去除乙硫醇时的催化活性,结果表明:在四氨基酞菁铝的作用下,乙硫醇的去除率达到了95％,催化活性能够持续540 min.然而四硝基酞菁铝对乙硫醇的去除率只有88％,而且催化活性仅仅有270 min.这是由于酞菁环上的取代基不同,氨基是一个供电子基团,使酞菁环上的电子云密度增大,有利于电子的传递,从而增加了催化活性.%With the development of economy, all kinds of vehicles are increasing rapidly. So a large number of fuel oil is used. Sulfur compounds in fuel combustion have become sulfur oxides, which seriously pollute the environment. In order to protect the environment, to reduce sulfur compounds in fuel oil, aluminum tetraaminophthalocyanine complexes were synthesized, and its structure was characterized by elemental analysis, IR spectra and UV Vis spectra, and then using aluminum tetraaminophthalocyanine as desulfurization catalyst, its catalytic activity was investigated by determining ethyl mercaptan removal rate. The results showed that, using aluminum tetraaminophthalocyanine as desulfurization catalyst, ethyl mercaptan removal rate reached 95％, the catalytic activity sustained for 540 min. However, using aluminum tetranitrophthalocyanine as desulfurization catalyst,the removal efficiency of was only 88％, and the catalytic activity only sustained for 270 min. This was because the substituents on the phthalocyanine ring were different, and the amino group was a donating electron group. The density of the electron cloud on the phthalocyanine ring was increased, which was favorable for the electron transport, thus increasing the catalytic activity.
