In order to study the possibility of enriching jet fuels with diamond-like hydrocarbons to improve their physicochemical and operational properties the catalysis of narrow 10-degree fractions of marine oil in the range of 190-250°С with aluminum bromide was realized. The catalysis products were taken at various times and analyzed by chromatomass spectrometry. It was shown that the non-adamantane hydrocarbons and the “naphthene background” disappeared completely on the mass-chromatograms with m/z 135, 149, 163, and 177. The formation of new thermodynamically unstable adamantane isomers was observed at the initial stages of catalysis with the formation of high-molecular adamantanes from the low-molecular compounds at the later stages. It was found that hydrocarbons of the С₁₂–С₁₄ adamantane series are formed from the “naphthene background”. It is suggested the reason for the formation of high-molecular adamantanes from the low-molecular compounds is transalkylation.

为了研究用类金刚石碳氢化合物富集喷气燃料以改善其物理化学和操作性能的可能性，实现了用溴化铝催化 190-250°С 范围内的 10 度海洋石油窄馏分。在不同时间取出催化产物并通过色谱质谱法进行分析。结果表明，非金刚烷烃和“环烷烃背景”在 m/z 135、149、163 和 177 的质谱图中完全消失。在初始阶段观察到新的热力学不稳定金刚烷异构体的形成。催化后期由低分子化合物生成高分子金刚烷。发现 С ₁₂ –С _{14的碳氢化合物}金刚烷系列是由“环烷背景”形成的。建议由低分子化合物形成高分子金刚烷的原因是烷基转移。
