I lifted this from a website about camp stoves old & new. It doesn't
explicitly say it but I suspect naphtha burns the hottest.

*Naphtha (aka. Coleman Fuel, MSR Fuel, White Gas [North America, Australia,
and New Zealand], Shellite, Fuelite, Zippo fuel, Ronsonol fuel, heptane,
Blazo, cigarette lighter fluid, some charcoal lighter fluid)*
Naphtha is a term relating to a range of hydrocarbons used as solvents or
feedstock for petroleum products. For purposes of categorizing fuels for
stoves, "naphtha" is used to include all naphtha and gasoline-like fuels
that have been refined to be as aromatic and additive free as practical for
stove use. This is a much "cleaner" stove fuel than other petroleum
products (except possibly the liquefied gases) so it is less likely to clog
stoves. It is also considered by many to be the best fuel for high altitude
and extremely cold treks. It evaporates quickly, is quite volatile, burns
very hot, and leaves little residue compared to kerosene. Naphtha requires
a lot of oxygen to burn and therefore may be a little easier to extinguish
than other petroleum fuels. Naphtha is much more explosive than kerosene
but is a bit less explosive than gasoline. This fuel category might be
slightly less toxic than gasoline but is still very caustic, and releases an
unpleasant odor that lingers.
Naphtha is a mix of 5 to 9 carbon alkanes with a boiling range of 104 to
401°F (40 to 205°C). The term "naphtha" has several accepted and obsolete
definitions and can even be inclusive of gasoline and kerosene.
*Coleman Fuel (Calumet Lantern Fuel )*
Coleman fuel contains about 50% naphtha, 50% aliphatic petroleum
distillates, 2% xylene, 2% toluene, 0.5% benzene, green dye and rust
inhibitors (to help prevent rusting of internal parts and facilitate long
shelf life). The carbon number range is C5 to C9 with a boiling point range
of 100-350° F. Coleman Fuel contains up to 25% n-hexane and up to 15%
cyclohexane by weight and it is fully hydrotreated to remove aromatics,
(reported to contain less than 0.001% benzene).
*Fuelite (Shellite)*
Contains >60% Paraffins and naphthenes, N-hexane 13%, <5.0% Aromatic
hydrocarbons (3.5% Toluene, 1% Ethylbenzene, <0.5% Benzene, 1% C8 and higher
aromatics) and other stuff
*White Gas*
This is an old term referring to overpriced unleaded gas marketed as lamp
and stove fuel back when leaded gas was referred to as Red Gas. True white
gas is gasoline without additives, is more volatile than true naphtha and
not as safe to use. Some white gas (not made for stove use) even has
tetraethyllead added to it.
