The chemical characteristic and distribution of polycyclic aromatic compounds occurring in the core from the South China Sea are studied. The compositions of polycyclic aromatic compounds are the series of naphthalene, phenanthrene, fluorene and chrysene. There are a few isomers of dimethyl and trimethyl naphthalene compounds present in 0~100cm layer. Nine isomers of dimethyl naphthalene and six isomers of trimethyl naphthalene are in 400 - 500cm and 700~800cm layers, with 1, 2-dimethyl naphthalene predominant...

The chemical characteristic and distribution of polycyclic aromatic compounds occurring in the core from the South China Sea are studied. The compositions of polycyclic aromatic compounds are the series of naphthalene, phenanthrene, fluorene and chrysene. There are a few isomers of dimethyl and trimethyl naphthalene compounds present in 0~100cm layer. Nine isomers of dimethyl naphthalene and six isomers of trimethyl naphthalene are in 400 - 500cm and 700~800cm layers, with 1, 2-dimethyl naphthalene predominant in the two layers. phenanthrene fraction is higher in value and most variant in isomers among the aromatic compounds. The series of fluorene compounds contain fluorene, furan, thiophene, benzene fluoreneone and pyrrole. The occurrence of chrysene and retene indicates that the source of sedimentary organic matter is derived from terrenstrial higher plants. The low maturity of the sedimentary organic matter is demonstrated by the fact that 1) absence of methyl naphthalene (α- or β-) compounds; 2 ) low ratio between the isomers of dimethyl naphthalene; 3) low indices of methyl and dimethyl phenanthrene and 4) low coefficient of fluorene.

报道了南海北部沉积物中萘、菲、芴、蒽、芘和茁化合物的组成和分布.在0~100cm试样中含有少量的二甲基萘和三甲基萘化合物,400~500cm和700~800cm层段中的二甲基素有9个异构物,6个三甲基萘异构化合物,并且均以1,2-二甲基萘占优势.菲化合物在芳烃组分中含量最高(27%~42%),异构化合物亦最多.芴系列中有药、氧药、硫芴.苯并芴酮和氮芴等.茁和惹烯的存在,表明沉积有机质的母源物质来自陆源高等植物.二甲基萘异构化合物的比值、甲基菲和二甲基菲指数、芴系数,以及缺乏甲基萘等,标志南海北部沉积物的有机质成熟度低.

There are significant differences in distribution and compositions of the aromatic hydrocarbons from various Tarim oils. The terrestrial oils have relatively low amount of naphthalene and dibenzothiophene (1.41%─3.07%) homologues, and abundant phenanthrene, biphenyl (with an average of 20.4%) and dibenzpfuran homologues, with predominance of l,2,5─trimethylnaphthalene and l,2,5,6─tetramethylnaphalene in naphthalene homologues. The marine oils are characterized by abundant dibenzothiophene compounds (7.7%─31.4%)....

There are significant differences in distribution and compositions of the aromatic hydrocarbons from various Tarim oils. The terrestrial oils have relatively low amount of naphthalene and dibenzothiophene (1.41%─3.07%) homologues, and abundant phenanthrene, biphenyl (with an average of 20.4%) and dibenzpfuran homologues, with predominance of l,2,5─trimethylnaphthalene and l,2,5,6─tetramethylnaphalene in naphthalene homologues. The marine oils are characterized by abundant dibenzothiophene compounds (7.7%─31.4%). These differences suggest that the two oil families have different depositional environment and original organic mattere source. According to aromatic maturity parameters, these oils have equivalent R.. values from 0.6% to 1.1%. The aromatic maturity indicators of the oils, to some extent, are affectted by the lithology of their source rocks.

塔里木不同类型原油的芳烃分布和组成有较大差异。陆相原油的萘系列、二苯并噻吩系列(1.41%─3.07%)较少;菲系列、联苯系列(平均值20.4%)和二苯并呋喃系列较丰富;萘系列中有较高的1,2,5─三甲基萘和1,2,5,6─四甲基萘。海相原油中二苯并噻吩化合物含量高(7.70%─31.24%)。这反映出两类原油成油母质的沉积环境和生源的差别。芳烃成熟度指标表明,这些原油相当的R0值在0.6%─1.l%范围。在一定程度上原油芳烃成熟度指标受源岩岩性的影响。

Effects of diluent properties on phase separation properties in solvent extraction of copper has been investigated.The chemical compositions of organic phase in interfacial crud from solvent extraction of copper in Dexing Copper Mine are identified by combined gas chromatography mass spectroscopy.It is found that main impurities in the organic phase are degradation products of Lix84 and nonylphenol ,and methylnaphthalenes,di methylnaphthalenes and tri methylnaphthalenes which originated from commercial 260 #kerosene.The diluent is unfavorable to phase separation because arenes with condensed rings and unsaturant are contained in it .The physiochemical and phase separation properties of 260 #kerosene can be modified by proper sulfonating and stable interfacial emulsion is not yielded.

用气相色谱质谱联用分析仪鉴别了萃取界面污物中有机相的化学成分 ,发现其中存在有萃取剂降解产物和甲基萘、二甲基萘、三甲基萘等稠环芳烃。稀释剂 2 6 0 #工业煤油中由于含有稠环芳烃及其它杂质而使萃取分相性能变坏。通过适当的磺化方法可使稀释剂的物化性能和分相性能得以改善 ,最终达到防止乳化的目的。
