2-硝基酞菁铝的合成及其催化活性研究

The Research of Synthesis and Catalytic Activity of Aluminum 2-Nitrophthalocyanine Complexes

空气中的硫氧化物主要来源于油品中乙硫醇的燃烧,为了降低空气中的含硫化合物,必须降低油品中乙硫醇的含量。首先合成了2-硝基酞菁铝,通过元素分析、红外光谱及紫外可见光谱对2-硝基酞菁铝进行了表征,然后以2-硝基酞菁铝作为去除乙硫醇的催化剂,并和2-羧基酞菁铝及四硝基酞菁铝作为催化剂进行比较。结果表明,2-硝基酞菁铝的催化活性能达到91.6%,持续330 min,虽然没有2-羧基酞菁铝的催化活性高,但比四硝基酞菁铝的催化活性高。

The sulfur oxides in air mainly come from the combustion of ethyl mercaptan in oil. In order to reduce sulfur compounds in air, we must reduce the content of ethanethiol in oil. Firstly, the synthesis of Aluminum 2-nitrophthalocyanine,by elemental analysis, Aluminum 2-nitrophthalocyanine was characterized by infrared spectroscopy and UV Vis spectra, and then to Aluminum 2-nitrophthalocyanine as a catalyst to remove ethanethiol, Aluminum 2-carboxylphthalocyanine and Aluminum tetranitrophthalocyanine as catalyst were compared. The results showed that the catalytic activity of Aluminum2-nitrophthalocyanine reached 91.6%, which lasted for 330 min. Although Aluminum 2-carboxylphthalocyanine had high catalytic activity, it had higher catalytic activity than Aluminum tetranitrophthalocyanine.
