Electrical Conductivity of Fluids

[mcesm2]

Hello,

I am after the electrical conductivities of a number of reasonably common fluids. I've looked in a number of literature sources but these properties have been, so far, fairly elusive. Does anyone know of any literature sources that have any data on electrical conductivity?

The fluids I'm after are:

Toluene
Xylene
Butyl acetate
Ethyl methacrylate


Thanks,
Shaun

Perhaps the dielectric constants might be helpful. I have tables for selecting ultrasonic level instruments.

Toluene dielectric constant is 2.4
Xylene dielectric constant is 2.3
Butyl acetate dielectric constant is 5.1
Ethyl methacrylate dielectric constant is 5.7

The dielectric constand pertains to the ability to conduct alternating current. The dielectric constant of a vaccum is one. Distilled water is 34. The dielectric constants are published for specific temperatures.

JLSeagull,

Thanks for the response it is much appreciated. I have heard dielectric constants mentioned along these lines but could not find any data on the above fluids.

Regards,
Shaun.

I just looked in my old CRC handbook because we are ordering a level controller. Methane, ethane, propane all run in the 1.7 area.

Not checked for the fluids you refer but Endress+Hauser has a pretty good reference on Dielectric Constants.

Googling for static charge relaxation (aka decay) times I found the following values for conductivities in mho/cm at 25 Celsius:

Toluene: 5[×]10[sup]-14[/sup]
m-Xylene: 9[×]10[sup]-14[/sup]
Butyl acetate: 2[×]10[sup]-8[/sup]

I didn't find anything on ethyl methacrylate.
