Methylated Spirits / Methyl Hydrate

[VocalNeal]

I need some Methylated Spirits or as North Americans would say Methyl Hydrate. Firstly I don't know what it would be called in Thai and so far have not found any in local hardware shops. Just wondering if anyone has seen any for sale?

"Metho" Its great for displacing the water that accumulates in petrol tanks, also good in wiper washer fluid to help dissolve bugs on the windshield.

Would like to know too as I have never seen it.

Googling, I find methyl hydrate is a synonym for methanol, methyl alcohol. Cheap by the gallon in home pro type stores, They also sell it in smaller brown bottles in the village paint store. Looks like a loa khao bottle about 2/3 full

ask them for "metanon"

Methylated Spirits

Methylated spirits ("metho") is a mixture of ethyl alcohol (95%) and methyl alcohol (%5). The methyl alcohol is poisonous and is added to prevent the methylated spirits being used as cheap drinking alcohol.

Ethyl alcohol

Ethyl alcohol, or ethanol, is produced by the fermentation of sugars, or from direct synthesis from ethylene. It is a renewable energy source.

Ethanol's formula is C₂H₅OH. Its boiling point is 78.5 deg C, and its melting point is -117.3 deg C.

Ethanol burns with a hot, pale-blue flame. It is miscible with water. Uses include consumption in alcoholic beverages, a solvent, an anti-freeze solution, and a fuel. Ethanol is used as an additive to car fuel and is burnt with liquid oxygen in some rocket engines. When Ethanol is burnt in air, the results of combustion are carbon dioxide and water.

Methyl alcohol

Methyl alcohol, or methanol, is also sometimes called wood spirit. It is produced by the destructive distillation of wood, or by a synthetic process which involves reacting carbon monoxide with hydrogen gas.

Methanol's formula is CH₃OH. Its boiling point is 64.6 deg C, and its melting point is -97 deg C.

Methanol burns with a pale, non-luminous flame. It is poisonous and, if consumed, causes blindness, insanity, and eventual death. It is commonly used as a denaturant for ethyl alcohol, and is miscible with water.

Methylated spirits as a fuel

The energy released from burning ethanol is approximately 30 kJ/g. For comparison, the energy released during the combustion of propane and butane are about 50 kJ/g and 49 kJ/g respectively.

It is simple to use metho as a cooking fuel - simply place about 30 ml in a small metal container and light it. If you support a cooking pot over the flame, you can boil a litre of water in about 16 minutes - no special equipment required! I tried a stainless steel egg cup and it worked fine.

More efficient metho burners have a series of small holes which act as jets that the metho burns from. Such burners can boil a litre of water in about 8 or 9 minutes.

Its also usful to know that mixing metho with 10% water can reduce the soot produced when its burnt.

Safety precautions with metho

Although relatively safe compared to other stove fuels, metho is a flamable and toxic substance which needs to be handled carefully. Here are a couple of safety hints:

• Do not refill a metho burner until it is cool enough to touch. This is to avoid accidentally igniting the fuel bottle.
• Do not store metho in a container which you later intend to use to hold drinking water - you will not be able to get rid of the foul taste! It is best to store it in a properly labelled fuel container such as a Nalgene fuel bottle.
• If you get metho on your hands, rinse them thoroughly before handling food.

Names for methylated spirits around the world

In the UK, Australia, and New Zealand, metho is called methylated spirits. In the US and Canada its called denatured alcohol, methyl hydrate*, or fondue fuel. In Europe, it may be called spirits, brennspirits (Germany), alcool a bruler (France), or alcool etilico denaturato (Italy). It is generally available in hardware stores, supermarkets, service stations, and camping/outdoors stores. Methylated spirits may not be available in some countries due to alcohol restrictions (e.g. Pakistan).

Other uses for Metho

Metho is also a handy solvent for cleaning applications such as removing water based paint

also good in wiper washer fluid to help dissolve bugs on the windshield.

Windex works OK to.
