The result of simulated xylene formation conforms with that of industrial production, and xylene concentration can be controlled below 0.2

二甲苯生成反应的模拟计算结果与工业生产的结果相吻合，二甲苯的质量分数可控制在0.2％以内

Results: The 12 kinds of toxicants including methyl acetate, ethyl acetate, benzene, toluene, ethylbenzene, butyl acetate, p-dimethylbenzene, m-dimethylbenzene, o-dimethylbenzene, n-butanol, cinnamene and cyclohexanone were separated well. Good linear relationship sensitivity and reproducibility were obtained and detection limits (S/N=3) of them were 0.2 mg/l respectively. Conclusion: In this paper, a new method for simultaneous determination of 12 kinds of toxicants by using gas chromatography has been described.

结果：对乙酸甲酯、乙酸乙酯、苯、甲苯、乙酸丁酯、乙苯、对二甲苯、间二甲苯、邻二甲苯、正丁醇、苯乙烯、环己酮12种有毒物质的分离效果好，线性和重现性均较好，方法的检测限达到0.2 mg/L。

Enshi fire officers and men arrived at the scene, according to xylene has a high flash point, flammable, toxic, volatile and not soluble in water features, on-site incident commander ordered fire engines parked in the area upwind direction.

当日凌晨3时46分，沪渝高速宜昌往恩施方向崔坝服务区2公里处一辆载有二甲苯的槽罐车发生侧翻，二甲苯随即泄漏出来，带有浓烈刺激性气味的二甲苯在现场扩散。4时54分，恩施消防官兵到达现场，根据二甲苯具有高闪点、易燃、有毒、有挥发性且不溶于水的特点，现场指挥员命令消防车停靠在事故区上风方向。

There existed the specific interaction of xylenes molecule with framework of CoAlPO〓-5 due to introduction of Lewis sites by Co substitution, while xylenes were just condensed in AlPO〓-5, which would cause different adsorption selectivity of xylenes in them.

钴同晶取代AlPO〓-5分子筛骨架中的铝所引入的Lewis酸中心使二甲苯分子与骨架之间存在特殊相互作用，而二甲苯仅仅是浓缩在AlPO〓-5分子筛孔道中，这使得二甲苯在它们中的吸附选择性不同。

The toluene column bottoms is combined with the reformate splitter bottoms and Isomar effluent and sent to the xylene column. The mixed xylenes from the top of the xylene column are sent to the Parex unit where PX is recovered as product.

甲苯塔底物料与重整油塔底物料、异构化产物混合送到二甲苯塔，二甲苯塔塔顶的混合二甲苯送到吸附分离装置，在这里 PX 作为产品被分离出来。
