By means of chromatography-mass spectrography and gas chromatography, isoprenoids (i15-i20) have been identified in 49 crude oil samples and 3 rock samples from oil fields in Shengli, Huabei, Subei, Dagang, Liaohe and Daqing and also from Sichuan, Gueizhou etc. The relative contents, in percentage, of phytane (Ph), pristane (Pr), norpristane (i18), 2. 6.10-trimethyl-tridecane (i16)and farnesane (i15) are determined, as well as the ratios of Pr/Ph, Pr/nC_(17), Ph/nC_(18) and (i18+i16+i15)/(Ph+Pr). The curves of the relative contents of Ph, Pr, i18, i16 and i15 may show the character of different oils, useful for correlation purpose. The evolution of isoprenoids in crude oils is divided into sub-mature stage (Pr/Ph<0.8, (i18+i16+i15)/(Ph+Pr)=0.2-0.5); mature stage (Pr/Ph>0.8, (i18+i16+i15)/(Ph+Pr)=0.3-0.6) and highly mature stage (Pr/Ph>1.0, (i18+i16+i15)/(Ph+Pr)>0.6)

本文用色谱-质谱法和气相色谱法鉴定了胜利油田、华北油田、苏北油田、大港油田、辽河油田和大庆油田以及四川、贵州等49个原油和3个岩样中的类异戊二烯烷烃(i15~i20),测定了植烷(Ph)、姥鲛烷(Pr)、降姥鲛烷(i18)、2、6、10-三甲基十三烷(i16)和法呢烷(i15)的相对百分含量(五个组分的含量为100%),以及Pr/Ph、Pr/nC_(17)、Ph/nC_(18)和(i18+i16+i15)/(Ph+Pr)。Ph、Pr,i18,i16和i15的相对百分含量分布曲线可以表明原油的特征,用来对比原油。原油中类异戊二烯烷烃的演化可以分成低成熟阶段,成熟阶段和高成熟阶段。

In this paper, identification of Chinese medicinal herbs have been tried by pyrolysis-capillary gas chromatography. The pyrolytic behaviors of fouteen Chinese medicinal herbs have been discribed The herbs may be identifed on the basis of the retention Values and relative intensities of the characteristic peaks of their pyrolytic chromatograms. The condition of pyrolysis has been studied.

本文尝试用裂解—毛细管气相色谱法鉴定中草药,对十四种中草药的裂解行为进行了探讨。通过比较各中草药裂解色谱图中的特征峰或八个主要峰的保留值和相对强度,借以鉴定中草药;通过比较不同产地中草药特征峰的强度,借以评价中草药的质量。文中还对用裂解色谱法鉴定中草药的条件进行了探讨。由实验结果初步看出,裂解色谱法是可以鉴定和评价中草药的。

本文以对羟基苯甲酸、2,7-萘二酚、对苯二甲酸和少量的聚2,6-萘二甲酸乙二酯为单体制备了一系列具有不同配比的液晶共聚芳酯。用红外光谱法、直接裂解质谱法和裂解气相色谱法鉴定了共聚芳酯的分子链结构,指出共聚芳酯的分子链结构与所加5种单体链节结构基本一致。借助于热重分析仪研究了共聚芳酯的热稳定性及其与分子链结构之间的关系。结果表明:在空气介质中该共聚芳酯开始裂解的最低温度为320℃,裂解反应速度最快时的温度均高于490℃;并且发现,共聚芳酯的分子链结构对热稳定性有较明显的影响,链结构规整性好的共聚芳酯具有较高的热稳定性。实验结果指出,共聚芳酯在空气及氮气介质中的热裂解反应均分两步完成。正像文中的3号样品,空气中的第一步裂解反应在326℃开始发生,第二步裂解反应则发生在540℃左右。本文还探讨了共聚芳酯的热裂解机理。
