2025年2月25日 · Aldehydes and ketones can be converted to a hydrazone derivative by reaction with hydrazine (H 2 NNH 2). Hydrazone formation is a variation of the imine forming reaction discussed in the previous section. Hydrazones can be further converted to the corresponding alkane by reaction with a base, usually KOH, and heat.

The reaction of N(2)H(4) with OH has been investigated by quantum chemical methods. The results show that hydrogen abstraction mechanism is more feasible than substitution mechanism thermodynamically. The calculated rate constants agree with the available experimental data.

2021年6月24日 · It has been found that the H-abstraction mechanism (to form N2H3) is dominant relative to the SN2 reaction and OH-addition to the N center of N2H4 moiety (to form H2NOH + NH2).

2009年11月4日 · The reaction of N 2 H 4 with OH has been investigated by quantum chemical methods. The results show that hydrogen abstraction mechanism is more feasible than substitution mechanism thermodynamically. The calculated rate constants agree with the available experimental data.

2021年12月1日 · Hydrazine (N 2 H 4) and hydroxyl (OH) coadsorption on the Ni(211) surface is investigated using Density Functional Theory (DFT) based calculations. Effects of the vicinal steps and edges on the stability of various N 2 H 4-OH

2019年10月3日 · The detailed reaction mechanism of the N 2 H 4 + OH reaction is comprehensively reported for a wide range of conditions (i.e., T = 200–3000 K & P = 1–7600 Torr) using the CCSD(T)/CBS//M06-2X/6-311++G(3df,2p) level and the master equation/Rice–Ramsperger–Kassel–Marcus (ME/RRKM) rate model, which includes corrections of the hindered ...

肼(n2h4)，又称为联氨，溶于水呈碱性，类似于氨气，已知 n2h4 在水溶液中的电离方程式：n2h4+h2o⇌n2h+5+oh−，n2h+5+h2o⇌n2h2+6+oh−。 常温下，将盐酸滴加到联氨(N2H4)的水溶液中，混合溶液中 pOH[pOH=−lgc(OH−)] 随离子浓度变化的关系如图所示。
