Default Petroleum Ether????

Hi:

There is a type of ether that is called Petroleum Ether. A couple of friends of mine use it for years to clean lab test equipment. The concensus is that it will work for our Diesel and may NOT be on any restricted list. I guess that it can not be used to make meth etc.

Anybody know what this stuff is and can one buy it at a chemical supply firm? Will it work in our model Diesels?

One can always hope,

Franchi

Petroleum ether or "PET Ether" is not an ether (R-O-R) but a straight chain hydrocarbon (CnHn+2), much like gasoline, but a shorter chain, lower flash point.

see


http://en.wikipedia.org/wiki/Petroleum_ether

Petroleum ether, also known as benzine, VM&P naphtha (varnish makers' & painters'), petroleum naphtha, naphtha ASTM, petroleum spirits, X4 or ligroin, is a group of various volatile, highly flammable, liquid hydrocarbon mixtures used chiefly as nonpolar solvents. Chemically, it is not an ether like diethyl ether, but a light hydrocarbon.
Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene. It has a specific gravity of between 0.6 and 0.8 depending on its composition. The following distillation fractions of petroleum ether are commonly available: 30 to 40 °C, 40 to 60 °C, 60 to 80 °C, 80 to 100 °C, 80 to 120 °C and sometimes 100 to 120 °C. The 60 to 80 °C fraction is often used as a replacement for hexane. Petroleum ether is mostly used by pharmaceutical companies and in the manufacturing process. Petroleum ether consists mainly of pentane, and is sometimes used instead of pentane due to its lower cost.[1]
Petroleum ether, despite its synonym of benzine, should not be confused with benzene or benzyne, nor should it be confused with gasoline although many languages call that with a name derived from benzine, e.g. "Benzin" (German), "benzine" (Dutch), "benzina" (Italian) or "benzină" (Romanian). Petroleum ether is a mixture of alkanes, e.g., pentane, hexane, and heptane, whereas benzene is a cyclic, aromatic hydrocarbon, C6H6. Likewise, petroleum ether should not be confused with the class of organic compounds called ethers, which contain the R-O-R' functional group.
During the Second World War some extermination camps experimented by killing people with benzine injections.[2]
Petroleum ether is useful for removing the gum from self-adhesive stamps. It is the main ingredient of some 'label remover' or 'sticker remover' products.[3]

Is "Petroleum Ether/Benzine" the same as or related to Colemans's lantern fuel? Thanks

NO, NO and NO! No use for model diesels whatsoever-take it from a chemist. Let me spell it out-there is no other chemical in existence that will substitute for diethyl ether in model diesels-no other chemical compound has the combination of properties including miscibility, SIT, volatility, explosive limits etc that allows ether to function as it does in our fuel mixtures. Note that I use the word SUBSTITUTE-there is no other chemical that has similar properties that can be used as an ALTERNATIVE to diethyl ether in model diesel fuel. It IS possible-with a bit of work-to use fuels without ether-providing you start on an ether containing fuel, or use a heat gun to warm the engine up.

Petroleum ether is just a low cut napthenic hydrocarbon fraction, and may well have differing compositions from different suppliers. It is a fairly common solvent in organic chemistry labs-along with a host of others. There is also a range of chemical products known as 'Crown Ethers'- these too are of no use for model engine fuel.

It is the same chemical that is used for making pot oil.  It boils and evaporates at a very low temp.  and explodes in houses where these experiments occur.

I am curious, what is "pot oil" and what experiments would one do with it?

For smoking.  The illegal newer alternative to booze.

I thought pot oil was a low grade kerosene. Used for those round black road work lamps years back.

SPORT PILOT Yup thats the legal one, back then do not think the druggies want that one, you can thank them. for the amyl nitrate IPN issue also .msrtin
