Problems solved by technology

However, zinc electrodes generally have problems such as corrosion, deformation, dendrites, and migration under alkaline conditions, which shorten their lifespan.
In the past, the homogenization of mercury on the surface of zinc was often used to solve this series of problems, but mercury is a toxic and harmful substance that poses a huge threat to human health and environmental protection

Embodiment

[0012] (1) The structural formula of 2-octanone ethylenediamine:

[0013] .

[0014] (2) The preparation method of 2-octanone ethylenediamine is:

[0015] Measure 3.2 ml (20 mmol) of 2-octanone, dissolve it in 15 ml of absolute ethanol, then add it to a three-necked flask, and add 0.8 ml of ethylenediamine under a water bath at 50 °C (because ethylenediamine is easily lost by volatilization, so Make it slightly excessive), then add 1 ml of glacial acetic acid as a catalyst to start the reaction, after 3 hours of reaction, take out the three-necked flask and put it in the refrigerator to cool to 2°C, at this time, the glacial acetic acid becomes solid and precipitates, then filter to remove Remove the catalyst glacial acetic acid, and then use a rotary evaporator to evaporate the solvent anhydrous ethanol at 60°C to obtain a yellow-brown viscous substance, which is dried at 50°C to obtain a yellow-brown solid that is 2-octanone ethylenediamine.

Abstract

The invention discloses a Schiff base surface active agent named 2-octanone condensation-compound ethylenediamine and application thereof. The structural formula of the 2-octanone condensation-compound ethylenediamine is as follows. The 2-octanone condensation-compound ethylenediamine is applied to alkaline Zn-Ni batteries as mercury substituting corrosion inhibition additives and used for preventing corrosion, dendritic growth, deformation, migration and the like of zinc electrodes. The 2-octanone condensation-compound ethylenediamine can effectively prevent alkaline electrolytes from corroding the zinc electrodes. Moreover, the cyclic voltammetry and zinc migration experiments prove that the 2-octanone condensation-compound ethylenediamine plays good roles in inhibiting the dendritic growth, the deformation and the migration of the pasted zinc electrodes.

Description

technical field [0001] The invention belongs to the technical field of mercury-substituting corrosion-inhibiting additives for alkaline zinc-nickel batteries, in particular to a Schiff base surfactant 2-octanone ethylenediamine and its use as a mercury-substituting corrosion-inhibiting additive in alkaline zinc-nickel batteries Applications. Background technique [0002] With the development of society, the application of secondary alkaline zinc batteries is also increasing. At present, various portable electrical appliances are developing rapidly. Secondary alkaline zinc batteries are widely used in military, aviation, commercial and other fields. However, zinc electrodes generally have problems such as corrosion, deformation, dendrites, and migration under alkaline conditions, which shorten their lifespan. In the past, the homogenization of mercury on the surface of zinc was often used to solve this series of problems, but mercury is a poisonous and harmful substance that...
