丙烯基

Rice seed storage glutelin could be separated into three acidic and three basic subunit components by SDS-PAGE using 15%~25% gradient acrylamide gel.

利用15%～25%丙烯酰胺梯度凝胶的SDS-PAGE分析法可将水稻种子贮藏谷蛋白分离为3个酸性亚基和3个碱性亚基。

The reaction takes place as soon as 3a is dissolved in solution. With the presence of a tethering terminal vinyl group bound to the vinylidene ligand, the [2+2] cycloaddition of two C=C double bonds readily occurred.

当有一乙烯基键结在丙二烯基上，分子内的两个碳碳双键会马上发生[2+2]的环化加成反应。

The presence of a gem-diphenylmethylene moiety at the vinylidene ligand with the appropriate terminal vinyl or alkynyl group along with the proper steric environment implements such a novel reactivity in the ruthenium vinylidene complexes.

因此推测丙二烯基与末端的不饱和键确实可以进行一些分子内的反应，但是gem-diphenylmethylene 官能基需位於适当的立体位置方可进行。

It starts with an aldol-type condensation in which a solution of the now commercially available E -[3-(4-fluorophenyl)-1-(1-methylethyl)-1 H-indol-2-yl]-2-propenal, 4 , 5 in THF is added to the preformed sodium-lithium salt of tert -butyl acetoacetate 5 at room temperature in THF.

它从一个醛型缩合其中一个解决现在的电子商业可-[3-(4-fluorophenyl)-1-(1-methylethyl)-1吲哚-2-基]-2-丙烯醛、4，5年增加了预四氢呋喃钠-锂盐叔丁基乙酰四氢呋喃在常温5。

4R,5S,6R-5,6-Bis-allyl-6-aldehyde-γ-hexanelactone I-145 was prepared from D-arabinose by six steps. Compound I-145 underwent Mukaiyama-type intramolecular aldolization to produce bicyclooctane I-147 stereospecifically.

我们以D-阿拉伯糖为起始原料，经六步反应，得到(4R，5S，6R)-5， 6-二烯丙氧基-6-醛基-γ-己酸内酯I-145，然后I-145发生分子内的Mukaiyama式aldol缩合反应，完全立体专一性地得到环化中间体I-147。

The surface activity and micelle behavior of the copolymers in aqueous solution were deterimned by surface tension methods.

在水溶液中，聚N-异丙基丙烯胺大分子随著温度升高会产生分子链的折叠，它的最低临界溶解温度为3236℃﹝4﹞，即在低于LCST时，它能完全溶解于水溶液中，而在LCST之上，则会产生沉淀。

By using competitive adsorption of activated carbom to remove unfavorable influence of carbon in carbonaceous gold concentrate on leaching process, the leaching rate of gold concentrate can be improved to 88% as compared with 10%by direct cyanidation.

本文论述了利用活性炭竞争吸附作用，消除含炭金精矿中炭在浸出过程中的影响，使金精矿的浸出率可由直接氰化的10％提高到88％。
