查询词典 butanol

Determination of methyl ethyl ketone and sec-butanol by gas chromatography was reported.

丁酮在合成抗氧防胶剂N，N'-二仲丁基对苯二胺过程中是过量的，回收利用可以节省不少成本，但其可以加氢生成仲丁醇，有必要测定回收丁酮中仲丁醇的含量。

Side-stream experiment for the removal of sec-butanol from recycle butylenes by adsorption on adsorbent PUMS-01 was carried out in a methyl ethyl ketone unit.

对甲乙酮装置循环丁烯脱除仲丁醇吸附剂PUMS-01进行了工业放大实验，实验结果表明产品性能达到了小试实验的水平。

The infrared spectrogram of loaded organic phase illustrated that ethanol and butanol are Lewis bases when they act with hexanoic acid, octanoic acid, etc, and are Lewis acids when they act with TBP, etc.

利用红外光谱对萃取机理进行了探讨，证实了醇与己酸、辛酸等作用时表现出Lewis碱性，而与磷酸三丁酯等作用时表现为Lewis酸性。

The initial rate V0 was influenced by the ratio of molar concentration for butanol to hexanoic acid C(superscript 0 subscript ROH)/C(superscript 0 subscript HA)(at a range of 0.2-17). As C(superscript 0 subscript ROH)/C(superscript 0 subscript HA) decreases, especially when C(superscript 0 subscript ROH)/C(superscript 0 subscript HA), the V0 increases rapidly.

反应初始速率V0与正丁醇和正己酸摩尔浓度的比值C(上标 0 下标 ROH/C(上标 0 下标 HA)有关，在C(上标 0 ROH)/C(上标 0 下标 HA)=0.2-17范围内，随C(上标 0 下标 ROH)/C(上标 0 下标 HA)比值减小，初始速率V0增大，尤其是当C(上标 0 下标 ROH)/C(上标 0 下标 HA)时，V0迅速增大。

The esterification reaction kinetics of hexanoic acid with butanol, catalyzed by Novozym 435 lipase, was studied in water-in-oil microemulsions formed by alkyl polyglucoside C10G1.54/n-butanollcyclohexane/water buffer solution.

研究了Novozym435脂肪酶在烷基聚葡糖苷形成的W/O微乳液体系中，催化正丁醇与正己酸合成酯的反应动力学。

It studies the synthesis of n-butylacetate with acetic acid n-butanol as raw material,sodium bisulfate monobydrate as catalyst.

以一水合硫酸氢钠为催化剂，冰乙酸与正丁醇为原料合成了乙酸正丁酯。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
