  • 1.

    1. The physicochemical characteristics of resinous-asphaltene substances isolated from >450°C vacuum residues of different Azerbaidzhan crude oils been determined; integral structural analysis of molecules of the resins has been carried out.

  • 2.

    2. The molecules of the vacuum residue resins are based on compounds with a hybrid structure that are similar in skeleton to the structure of high-boiling aromatic fractions. The resin molecules contain about two polycyclic blocks built from an average of two condensed highly substituted benzene rings and (with the exception of highly paraffinic Sangachal'sk crude oil) four or five naphthenic rings, irrespective of the depth of occurrence and the site of oil production.

1.1. 测定了从阿塞拜疆不同原油450°C真空渣油中分离得到的树脂沥青质物质的物理化学特性;对树脂分子进行了整体结构分析。真空残渣树脂的分子是基于具有混合结构的化合物，其骨架与高沸点芳香馏分的结构相似。树脂分子包含大约两个多环块，由平均两个浓缩的高取代苯环和四个或五个环烷环组成(高石蜡的Sangachal'sk原油除外)，与发生深度和石油生产地点无关。

  • 1.

    1. The pyrolysis of p-xylene at temperatures of 830°–1000°C with different hydrocarbon partial pressures (argon/p-xylene=10 : 1, 20 : 1, 30 : 1) has been investigated.

  • 2.

    2. The suggested radical-chain mechanism of p-xylene pyrolysis at high temperatures has an initiation stage leading to the formation of a p-methylbenzyl radical.

  • 3.

    3. It is concluded that toluene is formed mainly by the hydrodealkylation of p-xylene under the given conditions.

1.1. 研究了不同烃类分压(氩气/对二甲苯= 10:1、20:1、30:1)下对二甲苯在830℃~ 1000℃温度下的热解过程。提出的对二甲苯高温热解的自由基链机制存在一个起始阶段，导致对甲基苄基自由基的形成。在一定条件下，甲苯主要由对二甲苯的加氢脱烷基反应生成。
