Studies of aromatic series compounds in source rocks 生油岩芳烃镏份中系列化合物的研究
The content of aromatic structures, polar groups in Daqing series fractions was lower than that in Iranian light series, at the same time, the oil-water interfacial activity of Daqing series fractions was lower than that of Iranian light series fractions. 结果表明,大庆减渣馏分较伊朗轻质减渣馏分的芳香共轭结构和极性基团含量少,界面活性低。
Complexans containing aromatic ring and phenolic hydroxyl series 含芳环和酚羟基系列的氨羧络合剂
The amide of the peptide bond in the Dipeptide inhibitors which included aromatic series amino acid showed trans configuration with the hydroxide of the benzene ring. There were seven bonds between them. 含芳香族氨基酸的二肽抑制剂中的肽键的氨基和苯环部分羟基端呈反式构型,它们相隔7个键位。
