摘要/Abstract

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-β-（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MADLI-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-β-（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。

Abstract:

The 4-(3,5-dicarboxy) phenoxyphthalonitrile as an intermediate was synthesized with 4-Nitrophthalonitrile and 5-hydroxy isophthalic acid as raw materials, followed by the purification by column chromatography. Afterwards, a new tetra -2(3), 9(10), 16(17), 23(24) - (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 MADLI-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.
