1.In the oxydehydrogenation of ethylbenzene an active coke,formed in the course of the reaction,is the catalytically active material.
在乙苯氧化脱氢过程中,生成了一活性焦炭,是一具有催化活性的物质。
2.The team identified 42 such molecules and settled on four to track with the nanoparticles: decane, trimethylbenzene, ethylbenzene, and heptanol.
研究小组确认了42的分子，选定其中4，利用纳米级粒子进行跟踪监。
3.two tech-nologies,hydroearbylation to produce ethylbenzene and carbonylation to propionic aldehyde and pro-pionic acid, are emphatically evaluated.
结果表明，烃化制乙苯经济性能较差，但技术、市场，议先考虑；
4.p-Ethyl-phenylacetylene was synthesized from starting materials ethylbenzene via five steps by acylation、reduction、dehydration、bromize、eliminition reaction.And the conditions were optimized.
