Dielectric Strength Of Liquids: looking for data

Click For Summary
The discussion centers on the search for reliable data regarding the dielectric strength of liquid insulators that possess high permittivity, low viscosity, and safety. The user inquires about specific liquids such as ethylene glycol carbonate, propylene glycol carbonate, ethanol, methanol, and various small organic compounds. They express difficulty in finding this information in standard references like the Handbook of Chemistry and Physics and Wikipedia. A suggestion is made to utilize the handbook's index for dielectric constants, specifically in the 84th Edition, while another participant recommends exploring more technical databases like Scirus and IEEE Xplore for relevant research papers. The context of the inquiry relates to the application of these liquids in an electrostatic alternator project.

Hello all of you!

I'm looking for reliable data about the dielectric strength (=breakdown field) of liquid insulators with a high permittivity and a low viscosity and not too dangerous.

Examples of such liquids:
- Ethylene glycol carbonate. Propylene glycol carbonate. Maybe the oxalates and sulphates.
- Ethanol. Methanol.
- Small ketones and aldehydes
- Small phosphates?
- Furfuraldehyde maybe.

I couldn't find them in my Handbook of Chemistry and Physics (1990), in Wikipedia, nor on the Web.

The use would be in an electrostatic alternator which looks very interesting (MW or GW range!), as I describe it there:

I suggest beginning to read on page 2 with the sketches and diagrams.

Thank you!

Learn to use the index of the handbook! Look under "Dielectric Constant - Liquids" . In the 84th Edition it is in Section 6 pages 155 to 177.
 
I already have all permittivities.

Where do you find the dielectric strength?
 
Thank you!
