Question

A compound dissolved in methanol and need to remove by distillation because heat is sensitive, a person hesitate to rait temp above 0C and instead decide to use vacuum distillaion. What required pressure for pure methanol to boil at this temp?

Answer 1

Methanol of course is another fluid which can be used with our water methanol injection systems. Either in pure form or mixed with water. Generally most users will run some type of water methanol mix. The most popular mix is 50/50. That is mixing 50% water with 50% methanol by volume. Not only does this make mixing easy, it's more affordable then using pure methanol and more importantly it's non-flammable. For most gasoline EFI forced induction applications, we recommend a 50/50 mixture.

The use of pure methanol is also quite common amongst users. With no water in the mix, users are able to run significantly higher amounts methanol through the engine. When running pure methanol it will make your air fuel ratio go very rich in which you will need to reduce fuel through the ECU to compensate for it. Technically, we are unlimited to how much methanol we can spray, as we are simply swapping one fuel for another.

Locating pure methanol can be difficult. Most race tracks, such as drag strips, sprint car tracks and go kart tracks, sell methanol. If you live near any them try them first. Additionally, many dyno shops have been found to carry it as well as performance speed shops. Try calling VP Fuels to see if there is a shop in your town which carries it. Other places you may try are hobby shops which sell remote controlled gas powered airplanes and cars and suppliers of industrial chemicals. If still no luck try one of the following online sources in which you can buy 5 gallon drums and have shipped to your house.
