辛烷

The catalyst was applied to hydrogenateα-octene in normal temperature and pressure, the conversion ofα-octene was 98.6%, and the yield of octane was 63.1% by the bimetallic catalyst.

CTS-ACRPd用于常温常压下α-辛烯的催化氢化，并在催化氢化过程中添加Ni~(2+)，Ni~(2+)-pd双金属催化剂催化α-辛烯的加氢反应150 min时α-辛烯的转化率为98.6%，正辛烷产率63.1%。

Addition of small amount of inert solution, such as, pentane and isooctane, to the bulk polymerization system is helpful to remove the reaction heat.

向本体聚合体系中加入少量溶剂如戊烷、异辛烷有助于改善这一问题，使反应平稳地进行。

Bromooctane was synthesized from potassium bromide(by-product of synthesizing 2-hydroxy-4-octyloxybenzophenone) and n- octanol using concentrated sulfuric acid as a catalyst.

以生产2-羟基-4-正辛氧基二苯甲酮的副产物溴化钾和正辛醇为原料，浓硫酸为催化剂，合成了溴代正辛烷。

The results indicated that compared with AOT reversed micellar system, SEDSS reversed micellar system has higher extract ratio, no undissolved substance on the interface, and need not co-surfactant.

结果表明，该表面活性剂与异辛烷形成的体系具有反胶束的性质，与AOT/异辛烷体系相比，血红蛋白的提取率更高，且无界面膜状物产生。

Adamantane and bicyclo (222) octane are predominantly Chlorinated at the bridgeheads by this procedure.

金刚烷和二环〔222〕辛烷主要是按照这个程序在桥头氯化。

Results showed that AOT reversed micellar systems provided a suitable micro-environment for biodiesel production. The optimal parameters were: the ratio of water and AOT 11, AOT concentration 50 mmol/L, temperature 40℃, pH 7, molar ratio of methano and oil 3, and rotating speed 180 r/min. The transesterification rate reached 90% when a 3-step methanolysis protocol was used.

研究结果表明： AOT/异辛烷反胶束体系为Candida sp.99-125脂肪酶催化提供了较为合适的微环境，在W0为11，表面活性剂浓度为50 mmol/L，温度为40℃，缓冲液pH值为7的AOT/异辛烷反胶束体系中，醇油摩尔比为3∶1，摇床转速为180 r/min，采用12h3次流加1 mol当量的甲醇，单批最高酯转化率可以达到90%。

Companies are producing various specifications heptane, n-heptane, iso-octane, n-hexane, and environmental protection-type special solvent oil, 120 # solvent oil, industrial products and reagents, welcome customers at home and abroad came to negotiate and buy.

公司现生产各种规格的庚烷、正庚烷、异辛烷、正已烷、环保型特种溶剂油、120#溶剂油等工业品和试剂，欢迎国内外客户前来洽谈、选购。

The addition of iso-octane extends the knocking limit in equivalence ratio somewhat, however the knock occurrence mainly depends on the total concentration of mixture. Although the operation range in equivalence ratio becomes narrow with the increasing of iso-octane, the maximum load is improved 80% by n-heptane/iso-octane controlled real-time in contrast with the HCCI fueled with n-heptane only.

结果表明：混合燃料HCCI着火以及燃烧相位主要取决于正庚烷实际的燃空当量比；异辛烷的加入对爆震当量比界限有所拓展，但HCCI爆震主要与混合燃料总当量比有关；随着辛烷值比例的提高，导致HCCI运行范围变窄，但是实时调控证明相对纯正庚烷，混合燃料的HCCI燃烧最大负荷提高了80%。

The results showed that, with increase of polymerization number , the activities of lipase in SEPESes/isooctane reversed micelles reached the maximum and then decreased. The lipase activity at optimal n (=2. 0) was 2. 2-fold of that in AOT/isooctane system.

结果表明，脂酶在SEPES／异辛烷反胶团中的活性随氧乙烯聚合数增大先增后降，在n=2.0左右达到最大，为AOT／异辛烷反胶团中的2.2倍。

The high selective resolution system was constructed with the mixture of isooctane with octanol acting as reaction medium and octanol as acyl acceptor.

建立了异辛烷／正辛醇的混合溶剂为反应介质、正辛醇为酰基受体的高度选择性的酯化拆分体系，并利用水合盐缓冲技术使反应过程中水活度保持恒定。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
