phenyl hydrazine

Adiabatic stability analysis of benzoyl hydrazine and p-Nitro phenyl hydrazine

苯甲酰肼与对硝基苯肼的热稳定性分析

The sodium salt condensed with phenyl hydrazine in the acid condition to prepare 1 phenyl 3 carbethoxy 5 pyrazolone .

用此盐与苯肼在酸性条件下进行加成缩合反应可制得1苯基3羧酸乙酯5吡唑啉酮。

The oxygen absorption and oxidation of acrylic esters will promptly increase in the presence of phenyl hydrazine and polymerization will proceed by using 0.1-1 % of phenyl hydrazine .

苯肼存在下丙烯酸酯的吸氧和氧化速度迅速增加，苯肼浓度约0.1&1.0%范围时，并发生聚合。

This paper studied that liquid natural rubber ( LNR ) was prepared respectively by four types of oxidative degradation agents ( phenyl hydrazine , nitrobenzene-hydrogen peroxide , potassium persulfate-propionaldehyde and periodic acid ) .

本文采用四种降解体系（苯肼、硝基苯-过氧化氢、过硫酸钾-丙醛和高碘酸）制备液体天然橡胶（LNR）。
