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学品的开发及生产进展,包括二苯甲酮、氯代甲、异氰酸、氯、酸物。

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

芳基甲烷在有机溶剂介质中、碱催下的氧缩反应,是成二苯乙烯(烷)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.

方法以过氧值(POV)法和DPPH法对提取物进行抗氧活性的测定,以维生素E(VE)和维生素C(VC)作抗氧性能对照。
