摘　　要：以4-硝基邻苯二甲腈和5-羟基间苯二甲酸为原料,合成中间体4-(3,5-二羧基)苯氧基邻苯二甲腈;在1,8-二氮杂二环十一碳-7-烯液相催化条件下,合成新型四(间二羧基苯氧基)酞菁钴化合物;通过柱色谱分离方法对中间体进行提纯,利用红外光谱、1H-NMR以及MALDI-TOF MS对中间体及最终产物进行表征。在液化气脱硫醇模拟体系中,对四(间二羧基苯氧基)酞菁钴的催化性能进行评定。结果表明,所合成的新型酞菁钴类催化剂对正丙硫醇和正丁硫醇转化率达到98.0%左右,对叔丁硫醇转化率达到68.2%,其脱硫醇性能优于工业应用催化剂。The 4-( 3, 5-dicarboxy) phenoxyphthalonitrile as an intermediate was synthesized with4-nitrophthalonitrile and 5-hydroxy isophthalic acid as raw materials,followed by the purification by column chromatography. Afterwards,a new tetra-( 3,5- discarboxylphenoxy) phthalocyanine cobalt was obtained from the intermediate under the catalytic action of 1,8-diazabicyclo undec-7-ene( DBU). The intermediate and the final product were characterized by mass spectrum,Fourier transform infrared spectroscopy( FT-IR),nuclear magnetic resonance(1H-NMR) and MALDI-TOF-MS techniques. The sweetening performance of the synthesized phthalocyanine cobalt was evaluated using mercaptan compounds and compared with the industrial catalysts. The sulfur conversions of n-propyl mercaptan and n-butyl mercaptan of the synthesized phthalocyanine cobalt are both around 98. 0%,and for t-butyl mercaptan the conversion is 68. 2%. The results show that the sweetening performance of the synthesized phthalocyanine cobalt is better than the industrial catalysts.
