diphenyl

This paper reviews the research and development of phosgene Derivates,including diphenyl ketone,chlorocarbonate,isocya-nate,acyl chloride and carbonates.

本文综述了光气下游精细化学品的开发及产进展,包括酮类、氯代酯类、异酸酯类、酰氯类、碳酸酯类化合物。

As the isocyan group is polymerized further, diphenyl carbondiimine may be formed, further polymerization of which forms a nitrogen-containing polycyclic aromatic compound.

异基化合物进一步聚基碳化亚胺，后者又聚合氮杂环的多环芳烃。

The oxidative dimerization of aryl methanes in organic solvents by using alkaline catalysts is an important way to prepare diphenyl ethanes and diphenyl ethylenes.

芳基烷在有机溶剂介质中、碱催化下的氧化缩合反应,是合乙烯(烷)类化合物的重要途径.

Methods Using the assay system of peroxide value (POV), diphenyl picryl-hydrazyl (DPPH), the antioxidative activities of various extracts were studied and comparedwith VE and VC.

方法以过氧化值(POV)法和DPPH法对提取物进行抗氧化活性的测定,以维素E(VE)和维素C(VC)作抗氧化性能对照。
