 Occupational Safety and Health Guideline For Ethyl Chloride
Ethyl chloride is a gas at room temperature and a volatile liquid when compressed, or at lower temperatures.
Before a worker is placed in a job with a potential for exposure to ethyl chloride, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.
Containers of ethyl chloride should be protected from physical damage and water or steam, and should be stored separately from chemically active metals such as sodium, potassium, calcium, powdered aluminum, zinc, and magnesium, oxidizing materials, or alkalis.

 Tetra-ethyl lead - Wikipedia, the free encyclopedia
TEL is a viscous colorless liquid, produced by reacting ethyl chloride with a sodium-lead alloy.
TEL has a very weak carbon-lead bond, and at the temperatures found in internal combustion engines it decomposes into lead and ethyl radicals, propagating the combustion by radical reactions.
TEL was once used extensively as an additive in gasoline (petrol) for its ability to increase the fuel's octane rating (that is, to prevent its detonation ("knocking") in the engine) thus allowing the use of higher compression ratios for greater efficiency and power.

In this regard, management of hydrogen chloride (and affiliated hydrochloric acid) within the process is a key issue to be resolved when a catalyst system capable of conversion of both ethane and ethylene into vinyl chloride monomer is used.
In contemplation of vinyl chloride facility construction, there is also a need to enable use of prior equipment as much as possible, where some existing equipment may have the ability to handle hydrogen chloride and other existing equipment does not have the ability to handle hydrogen chloride.
The invention further provides an apparatus for manufacturing vinyl chloride, comprising : a reactor for generating a reactor effluent stream by catalytically reacting together ethane, ethylene, oxygen, and at least one chlorine source of hydrogen chloride, chlorine, or a chlorohydrocarbon, wherein the molar ratio of said ethane to said ethylene is between 0.

I'm probably biased in my assessment of ethyl chloride from the fact that this liquid is used in medicine clinically as a local skin "chill" anaesthetic, and so I've gotten to work with it some.
I don't have the numbers, but I can predict that heat of fusion for ethyl bromide will be similar to ethyl chloride per MOLE and per VOLUME, but (mostly because bromine is heavier) only about 60% as much per weight.
The other main candidate is n-propanol, which melts at -126 C and has 25% better performance then ethyl chloride on heat of fusion (I have to say, however, that this compound had a really lousy looking phase transition in my experiments).

In such a design we'd have to have much thicker aluminum heat conductors radiating from the central ethyl chloride heat dump out to our hexagonal cryogrub cells ("cryogrub" = frozen TV dinner for whatever creatures come to inhabit the future Earth...), and essentially no insulation between conductor and the inside of our cells at all.
Still, it would be a much simpler design than one that had to deal with the 60 C temp gradient of LN2 to -135 all the time.
