查询词典 benzaldehyde

Adding Cr in the catalyst enhances the selectivity to benzaldehyde (from 85.6 to 91.2％ at 400℃). Cu or Ti is very beneficial for the hydrogenation of methyl benzoate to toluene or the hydrogenolysis of methyl benzoate.

Cr调变的催化剂提高了甲醛选择性(在400℃，从85.6提高到为91.2％)，Cu和Ti调变的催化剂则显示较高的苯甲酸甲酯深度加氢活性，即氢解活性。

A salt of iodic acid .A white or yellowish crystalline compound, C14H12O2, derived from benzaldehyde.

以对氯苯甲醛、丙二腈和α-萘酚为模板反应，离子液体可重复使用3次，其催化活性没有明显降低，同时还探讨了该反应体系下的可能反应机理。

In order to obtain higher effect antitumor drugs, we synthesized the derivatives of benzaldehyde nitrogen mustard and their metal complexes. Our works are concentrated on the following

为获得更好的抗肿瘤药物，我们以苯甲醛氮芥为母体合成了一系列它的衍生物及金属配合物，围绕这一课题做了如下工作

The biological activities of the metal complexes of derivatives of benzaldehyde nitrogen mustard were investigated against 〓,〓 and SMMC-7721 cell lines. The interesting results were found. When the non-activity ligand combines with cobalt and nickel , the complexes have good antitumor activity, while active ligand binds to the metal, the complex has no activity, indicating there are synergic effect and counteraction between the metals and the ligands.

对所获得苯甲醛氮芥衍生物的金属配合物进行研究，观察它们对SMMC-7721、〓细胞株的作用，发现某些有趣的实验结果，无活性的配体，当与钴，镍形成配合物后，具有很好的抗肿瘤活性，而有活性的配体形成配合物后无活性，揭示在它们存在有协同作用及拮抗作用。

In the research, toluene and xylene were employed as raw materials, Mn/Mn , Ce/Ce and Mn/MnO_2 as oxidative medias, respectively. Corresponding oxidants Mn, Ce, MnO_2 were electrolyzed through sonoelectrooxidation method, and were applied to oxidate the raw materials to prepare benzaldehyde and its derivatives under the ultrasonic radiation.

在研究中选择甲苯和二甲苯为原料，分别以Mn／Mn、Ce／Ce和MnO_2／Mn为氧化媒质，通过超声电氧化的方法，电解得到相应的氧化剂Mn、Ce和MnO_2，并在超声波作用下，将其用于氧化原料制备相应的苯甲醛及其衍生物。
