查询词典 react

The research conclusions above mean that polysilicic acid can react with hydrolyzed aluminum species to form aluminum-silicate polymer composite, which made the species distribution in PASC changed.

但对PASC而言，情况有所不同，在低碱化度和低Al/Si摩尔比情况下，Al13和Alb之间不存在对应关系，Al13和Alb比值远远小于1.0，随着B值和Al/Si摩尔比的升高，Al13/Alb比值逐渐趋近于1.0。

A successful leader is precontrol the things rather than react when it happened.

成功的领导者是事先控制事件，而不是事后才做反应。

A successful leader always precontrol the situation instead of react after it happened.

成功的领导者是事先控制事件，而不是事后才做反应。

A successful leader should precontrol the situation rather than react it after its happening.

成功的领导者是事先控制事件，而不是事后才做反应。

Promoted by metal dysprosium, aldehydes and ketones could react smoothly with propargyl bromide to afford the corresponding homopropargylic alcohol s in good to excellent yields, and no allenic alcohols were found.

在金属镝的促进下，醛、酮可与炔丙基溴反应，高选择性高产率地得到相应的高炔丙醇，没有发现连二烯醇的存在。

Promoted by metal dysprosium, aldehydes and ketones could react smoothly with propargyl bromide to afford the corresponding homopropargylic alcohols in good to excellent yields, and no allenic alcohol s were found.

当用苯基炔丙基溴代替炔丙基溴与醛、酮反应时，主要得到了相应的连二烯醇，而没有发现高快丙醇的存在，由此提出了六元环过渡态的反应机理

In previous results, Alkyl substituted propargylic dithioacetals treating with butyl lithium then were allowed to react with carbonyl compounds to form homopropargylic alcohol with high yields and highly regioselective.

在本实验室先前的研究中发现，烷基取代炔丙基硫缩酮与正丁基锂进行开环反应后，若是与羰基化合物反应，能够以高产率、具位向选择性的生成高炔丙基醇。

The resin is prepared by swelling chlorine balls in a solvent such as nitrobenzene; adding catalyst to obtain polystyrene-divinylbenzene adsorptive resin; removing reaction mother solution; washing to remove residual solvent and catalyst; swelling; adding pyrane reagent to further react with chloromethyl residual on inner and outer surfaces of the resin to obtain the pyranyl modified adsorptive resin with the composite function.

该树脂的制备方法：将氯球溶胀于硝基苯等溶剂中，加入催化剂，得到聚苯乙烯-二乙烯苯吸附树脂；抽尽反应母液，洗去残留的溶剂和催化剂；溶胀，加入吡喃试剂与树脂内外表面残留氯甲基进一步反应，可制得吡喃基修饰复合功能吸附树脂。

It was reported that benzylidenemalononitrile did not react with 1-benzyl-1,4-dihydronicotinamide. However, similar reaction easily takes place under the same condition when the phenyl group is replaced by the pyridyl group.

本课题组之前报道了苯亚甲基丙二腈在室温下不能被BNAH所还原，本论文将反应底物中的苯基换成吡啶基之后，在同样的实验条件下，反应可以比较顺利的进行。
