A leetle tricky. I don't believe they were invented until the
1930s, certainly not popularized untill then. (they are a manmade
compound.) (what happened was that the growing use of AC power led to
growing use of oil insulated transformers. HOT transformers & Hot oil
led to some nasty fires, with electric sparks to get things going.
Europe tended towards air insulated/cooled transformers. In the US
"inert" "oils" (Pyranol, a PCB mix was a common one) were used in oil
cooled/insulated gear. It was THOUGHT to be quite inert...

What we do have records of is Tesla working in C Springs with Glass
for dielectric & salt water for electrodes. I bet he GENERATED some Cl,
in passing. I have not seen records of what was used in
LI/Wardenclyffe. Tesla does describe working with oil immersed coils,
however i THINK these are all defined as mineral oil, or whatever.
