Talk:Methylated spirit

Azeotrope

The article mentions an ethanol/methanol azeotrope forms should ethanol denatured with methanol be distilled. I've searched high and low in the literature and find no such mention of an azeotrope. Can verify that such an azeotrope exists and if so at what temperature?

Temperature?

How hot does it burn F/C?

The D.A. lede

Some points in this original lede to the Denatured alcohol article still need to be worked-in to the now-merged article; I think this was stronger, more-succint lede:

Denatured alcohol is ethanol with added adulterants that make it useless for consumption as an intoxicating beverage by rendering it toxic or extremely distasteful to drink, but still useful for industrial processes or as a household chemical. This is done in order to make it exempt from taxes that apply to potable alcohol.

(By the way, the merge should probably have been discussed first.) Atlant 13:52, 30 May 2006 (UTC)

Sorry, did not mean to cause offence with the merge. Your new lead looks good, why not be bold and go ahead and put it in? Scheinwerfermann 15:16, 30 May 2006 (UTC)

Renaturating denaturated alcohol?

I've heard a rumour that Finnish alcoholics (is there a word for "puliukko" or "pultsari" in English?) have tried, more or less successfully, to renaturate denaturated alcohol by running it through slices of bread. Is this true, or just an urban legend? JIP | Talk 19:06, 29 June 2006 (UTC)

Whether or not something like this would work would depend on what the denaturing agent is; the chemical challenge is a lot different if the denaturing agent is a bittering agent versus if it's, say, methanol. Sounds like an urban legend to me.

Treatment via EtOH

(In a documented case, a shipworker poisoned while cleaning out a methanol tank was successfully treated with administration of a good portion of the liquor in the ship's "medicine chest.")

What was said there was taken from the paragraph below and, to me, that paragraph seems to be extrapolating on the facts given the paragraph the writer took it form (which I apsted below this paragraph)

Methanol (CH3OH) is a chemical feedstock of increasing importance as well as a commonly used solvent. In the early 1980s methanol production was introduced at a new petrochemical complex in the Saudi port of Jubail. A case is presented of a consultant supervising tank cleaning prior to methanol loading. He wore positive pressure breathing apparatus but no protective clothing. After 2-3 hours working in the confined space of the tank, he worked on deck and continued to wear his methanol-soaked clothing which eventually dried out. Visual symptoms of acute methanol toxicity presented some 8 hours after exposure. The appropriate treatment (with ethanol provided by the ship bond) was carried out in hospital and the individual recovered completely. Most reported cases of methanol toxicity are social in origin, arising from ingestion. This particular case, though unusual, does present some interesting lessons.

Denatured jam?

I don't understand this last line:

When making jam, add one teaspoon of fruit pulp to three teaspoons of methylated spirit. If the mixture makes a good clot, then the jam has sufficient pectin to set properly. However, the dye in the methylated spirit can make it difficult to see whether or not you have a good clot.

I thought the methylation of alcohol makes it toxic, as stated above in the article. Then what are we doing making jam with it? Someone with knowledge definitely needs to clarify this part.

Err, I'd assume that you don't put that jam back in the jam mix. Much like dropping some fudge mix in cold water tells you whether it's ready or not. No idea on this particular ideas veracity, however.--Limegreen 07:59, 14 December 2006 (UTC)

This really works. The pectin in the fruit juice is precipitated by the ethanol forming a jelly like clot. Obviously the test should be carried out in an old jar or something not intended for food use later. The mixture may be safely flushed down the drain with plenty of water after the test, it is not added back to the jam mix! :-) Socksysquirrel 00:49, 1 April 2007 (UTC)

Ph Level????

i need the ph level of methylated spirits for an assignment, and cannot find this information on the net. any help would be appreiciated.121.216.119.24 08:04, 27 August 2007 (UTC)

Move

Should this article be moved to denatured alcohol? Afterall, methylated spirits are only one type of denatured alcohol. --Rifleman 82 18:04, 14 September 2007 (UTC)
