I has searched the Coleman fuel and i can not fint the autoignition for the coleman fuel/white gas. Here are information about Coleman fuel:
http://www.coleman.com/coleman/msds/lantern.pdf
But these fuels are not same as our Norwegian language. I can see there are some words i searched for my language norwegian in similar to coleman fuel and white in this site: gashttp://members.iinet.net.au/~mbuckler/fuel/index.shtml#whitegas .

These fuels are full usable for the modeldiesel as fuel because these fuels are near same in ignition temperature range as kerosene, autodiesel and gasoline.

In Norway we used these fuels as kerosene, white spirit (paint cleaner), gasoline, autodiesel to our model dieselengines. White spirit and gasoline was used before 1950 years, after rare used, mostly used kerosene.

S.I.T. (Self ignition temperature / autoignition)
Autodiesel: 240...260 degree celsius
Kerosene: about 250 degree celsius
High cetane val. Gas oil: 220...240 degree celsius


About ether formula..

Ether is manufactured from ordinary from ethyl alcohol, two molecules of which join together, with the elimination of water, thus:

{C2H5-O-H + H-O-C2H5} = 2 Ethyl Alcohol -----> C2H5-O-C-2H5 + H2O = 1 Ethyl Ether Water

The process is usualy carried out by heating the alcohol with concentrated sulphuric acid, which absorbs the water formed-which is why the product is called "Sulphuric Ether". The ether which distils over is washed free from acid, purified, dried and re-distiled. It therefore contains no acid whether it is sold as "Anaesthetic Ether"


These ether sold under difference names as: Dietylether, anaesthetic ether, Ether .720, Ether B.S.S. 759,
Sulphuric ether, Ether Meth. , Ether "Nafta".

These unuseful ether: Amyl ether, Butyl ether, Isopropylether cause too high S.I.T. and is not suitable for use in dieselfuels.

Lower S.I.T. =much easier to ignite and burn the mainfuel as kerosene..
