Taking trimethylbenzene precise distillation for example,a new heat integration technology for energy saving was put forward.

以三甲苯精密精馏过程为实施案例，对多塔分离过程提出了热集成节能工艺。

Through the measurement of liquid-liquid equilibrium of DMSO-multicomponent heavy aromatics-tetradecane system, it was found that the concentration of trimethylbenzene and 1-methylnaphthalene had more effects on the distribution coefficient of other aromatics than that of the naphthalene and 2-methylnaphthalene.

用单一溶剂DMSO对多组分混合芳烃进行了萃取实验，发现在混合重芳烃中，三甲苯和1-甲基萘的浓度对其它芳烃分配系数的影响大于萘、2-甲基萘等对分配系数影响。

Methods 100 mg of muscle of rat corpse was preprocessed before trimethylamine was extracted with anhydro-methylbenzene, then trinitrophenol was added into extracts, and yellow compounds emerged. The optical density was detected by spectrophotometer at 410 nm and the concentration of TMA-N was calculated using the standard curve. Results There was good linear correlation (R^2=0.9991, P.001) between OD and the concentration of TMA-N in the range of 1~10 mg/L.

大鼠肌肉组织样本100 mg经预处理后，将三甲胺抽提于无水甲苯中，与苦味酸作用，形成黄色的苦味酸三甲胺盐，用分光光度计在410 nm处检测吸光度，标准曲线法计算TMA-N含量。

The steady state kinetics of the lignin peroxidase catalyzed oxidation of veratryl alcohol by H2O2 in a sodium bis(2-ethylhexyl) sulfosuccinate/isooctane/toluene/water reverse micellar medium was studied and a comparison with the corresponding aqueous medium was made to understand the effect of the reverse micellar medium on the catalytic mechanism and kinetic parameters.

为了理解木素过氧化物酶在反胶束介质中的催化性能与动力学行为，本文以LiP催化过氧化氢氧化藜芦醇反应为模型反应，研究了2-乙基己基琥珀酸磺酸钠/异辛烷/甲苯/水反胶束中上述模型反应的稳态动力学并与水介质做了比较。

Thus. Treatment of CR1R2=C=CH2 (R1 = R2 = Me; R1 = H, R2 = n-Bu; R2 = Ph; R2 = cyclohexyl; R2 = cyclopentyl, R2 = C6H5O, R2 = 2-IC6H4O, R2 = 4-IC6H4O) with bisdiborn in the presence of Pd2 (5 mol %) and 3-iodo-2-methyl-2-cyclohexen-1-one (5 mol %) in toluene at 80 oC gave products bearing both vinylic and allylic boron moieties in good to excellent yields.

但我们发现可以使用Pd金属错合物与有机碘化物共同催化下的系统，来进行此种加成反应。溶剂的选择以甲苯为最佳，Pd错合物以没有强配位基存在为最好的选择。

The GC-MS results indicated that a small quantity of lesser carbonnumber of aldehyde compounds were included in the organic compounds of PM, besidesbiggish carbon number of fatty hydrocarbon and volatilizable aromatic hydrocarbon, such asbenzene, methylbenzene, dimethylbenzene and etc.

GC/MS定性分析结果表明，在颗粒物所含有机化合物中，除了含有较高碳数的脂肪烃化合物、芳香族化合物如：苯、甲苯、二甲苯等低沸点易挥发的化合物外，还发现了微量的低碳数醛类化合物。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
