chemical prodution of co

[Rémi]

Hello all...

In this time, i studie the dehydratation of formic acid in the sulfuric,
for chemical production of carbon monoxyd, but i ask me just one
question :

I read then only 500 ml of formic acid in only 250 ml of sulfuric acid,
can produce 250 liters of carbon monoxyd gaz, it really true ?

somebody can me other inforamtion about this methods, cause i want take
a minimal of risks...

Formic acid can be as concentrated and quite cheap at 98% bw.
Knowing HCO2H to be the formula of such acid.
H-CO-OH --> C=O + H2O (catched by the conc H2SO4/oleum)
From this you see that one mole of formic acid can free one mole of CO.
Thus 46g formic acid free 1 mole of CO and 18g water.
460g will free thus 224,1 L at STP and 500g almost 250 L

But the real question is what is the density and % of your formic acid?
Because at 100% d>1 --> 500ml -> weight>500g --> over 250L

Minimal risk is to do much less until process is masterised and fully
known.
Efficently working fumehood necessary.Safety labcoat, glasses and
respiratory kit under hand.

HA okay, really thank you, you are really strong...

My formic acid density is 85%....

Juste two last little questions :

1 : The reaction of sulfuric/formic produce heat, how many degrees
maximal can that you it reach?


2 : What is the ideal proportioning of formic/acid for the best
production of CO ? Me I makes one volume of sulfuric, and the double of
volume of formic, what think about it?

I have a protection suit with one bottle of oxygen, for protect me, in
my lab, i think then i'm in security with that...

Thank you...

i've only read about this reaction, so i have no real practical
experience. that being said, its relatively exothermic. you may be
able to moderate it somewhat with an ice bath.

BE CAREFUL!!!!! your blood's hemoglobin PREFERENTIALLY absorbs CO
BEFORE it absorbs O2. your suit should be positively pressurized and
you should be on full O2.

what you are doing is VERY dangerous, especially if you are in a
closed room. will anyone else be in the building? what does the
building have for ventilation? you could effect people rooms away....


what are you going to do with this much CO?

-The temperature of the lowest boiling temperature --> arround 100°C for
formic and water.

-Seems good as long as H2SO4 is concentrated and idealy contains SO3.

-Do the people arround you have one too? Imagine your tiny brother, or your
girlfriend coming in the room...
