用自行安装的精密静弹燃烧量热计测定了四苯基卟啉(TPP)、四甲苯基卟啉(T_((PCH)_3)PP)、四对甲氧苯基卟啉(T_((P-OCH)_3)PP)和四邻氨苯基卟啉(T_((O-NH)_2)PP)的标准燃烧能,并计算出标准生成焓。样品 1.将苯甲醛加入沸腾的丙酸中迥流30分钟后冷至50～60℃,加入乙醇,冷却,过滤,紫色产物用甲醇洗,干燥后得TPP粗品。将粗品溶于迥流的二氯甲烷,加入溶于苯的DDQ迥流30分钟,蒸除溶剂,残渣溶于氯仿,氧化铝-氯仿柱层析,氯仿-甲醇重结晶制得纯TPP.
(TPP), tetramethylporphyrin (T_ (PCH) _3) PP) and tetrakis (methoxyphenyl) porphyrin (T_ ( P-OCH) _3) PP) and tetra-o-aminophenylporphyrin (T_ ((O-NH) _2) PP) were calculated and the standard enthalpy of formation was calculated. Sample 1. Add benzaldehyde to boiling propionic acid for 30 minutes, cool to 50-60 ° C, add ethanol, cool and filter. The purple product is washed with methanol and dried to give crude TPP. The crude product was dissolved in methylene chloride. The DDQ dissolved in benzene was refluxed for 30 minutes. The solvent was distilled off. The residue was dissolved in chloroform and purified by alumina-chloroform column chromatography to give pure TPP by recrystallization from chloroform-methanol.
