摘要
以四氢萘、1 甲基萘及十六烯等模型化合物为主 ,考察了不饱和烃类在氧化过程中氢过氧化物含量的变化 ,并对最终氧化产物进行了GC/MS分析。结果表明 ,萘满类非常活泼 ,很容易被氧化产生氢过氧化物及其它含氧化合物。四氢萘通空气氧化 30h后 ,体系中氢过氧化物的含量达5.0 1 % ,最终氧化产物有 1 四氢萘醇、1 四氢萘酮及四氢萘 1 酮 4 醇等 ;1 甲基萘的氧化产物主要是 1 萘甲醇和 1 萘甲醛 ;十六烯的氧化产物主要是长碳链醛及环氧化合物等。四氢萘与十六烯共存有协同氧化作用 ,使体系中的氢过氧化物含量在 1 6h高达 4.64% ,氧化深度增大。
The changes of hydroperoxide content during the oxidation course of unsaturated hydrocarbons were investigated by using tetralin, 1 methyl naphthalene and hexadecene as model compounds. The final oxidation products were analyzed by GC/MS. The results indicated that tetralin was easily oxidized into hydroperoxide, and the hydroperoxide content reached 5.01wt% after 30hr air oxidation together with the formation of other oxides, such as 1 tetralone and 1 tetralol, etc. Tetralin showed synergistic action with hexadecene, which accelerated the oxidation and increased the hydroperoxide content up to 4.64wt% after 16hr oxidation.
