today, i mixed 12L solution of 75methanol:25water and the mix got hot. Could feel the heat thru a 1/4" thick fuel jug...

what possible reaction is there between H2O and CH3OH that will cause the exotherm

methanol = CMOS grade
water = 18MOhm DI, fresh from tap

chemistry guru?

 

i believe you are looking at co2 and h2 being made as a byproduct of ions

 

It is an exothermic reaction, btw.

Methanol also forms co2 and h2o when it burns.

The product "heet"(used to take water out of gasoline) is actually methanol or a mix of methanol.

 

something is reacting...

i read of this effect from c6c6ch3vo post. tried a 100cc mix in a foam cup a few months back and temp went up

I am no chemist but arent you suppose to be using distilled water? Not that it changes your findings at all. But I was always told distilled water only.

 

I think distilled water is used to keep the jets from clogging with minerals and other junk

 

the water is very very very pure......18MOhm resistivity...

 

There will always be very low volumes of Hydrogen and Oxygen atoms in water, and in methanol; Carbon, Oxygen and Hydrogen atoms. Those "loose" atoms will join in a exothermic reaction to make H2 and Co2.

 

not a chemist, but a chemical engineer if that counts, lol. When you dilute meth with water, there is an exothermic reaction. Not sure of the chemistry, but it is fact. The heat generated shouldn't be extreme (i.e. melt the container), but you will see a temperature rise.

 

should the H2O be added to the meth or visa versa? if it rains on my car am I in trouble?

 

Pouring one into the other will not matter as it wont melt or burn anything.

Although, I would avoid getting water on your car, it might catch on fire.

 

I mix 50/50 and when I mix the two together the jug gets really warm. When I pour it in the car the tank in the car will get really cool after a while. I dont really woryy about it.

 

Sweet, can't wait to find this out when I get my Snow kit this week

 

yea first time i mixed the two i freaked out...then just hit the chem books up and was relieved...it definitely gets hot though...

 

I also noticed that mixing the two creates heat. Fortunately I know so little chemistry, I just figured it was normal, lol.
