Butane and propane are gaseous on this planet. Unless you're planning to
put
the items in question actually inside the pressurised container.

Christian.

Butane is liquid at STP

A rapidly boiling liquid.
It will last a fair time if you have an open bucket though.
Much as a bucket of water will in a 120C oven.

By that argument Carbon Dioxide is a solid at STP as, if you get a big chunk
of it, it lasts a fair while )

The statement "is a liquid at STP" is generally inferred as meaning "when
the whole mass of the liquid is at 0degC"

Isn't STP 25C, 760mm?

I think that's RTP

STP is 0C and 101325Pa (not exactly sure how the temperature is defined)

I got a small can of cigarette lighter fuel (the liquid stuff) to use

pads".

In the can of lighter fuel it refers to "petrol lighters".

Does this mean that for my purpose I could have simply used some
orinary car petrol?

Or is lighter fuel made of a different composition to car petrol?

There are a couple of commercial products sold for similar purpose.
Goof-Off and Goo-Gone. One of them will remove paint, I forget which
is which.

The message
from Chris Street contains these words:

butane
0.5C is the boling point at standard pressure according to my reference.

I think you may have missed the "-" sign. All the referrences I can find
give it as -0.5°C.

And given that most dry land is above sea level you can expect for
practical applications it'll boil lower than that.

if you pour 'em out into a jar they'll stay liquid for some time,
merrily boiling away as they absorb energy from the surroundings to
achieve their latent heat of evaporation. During this stage it's quite
possible to use them as liquid solvents

ok, i'm picturing this liquid do a great job of separating the bad
from the good, then.... the liquid evaporates, leaving the bad still on
the good.

obviously, i have an incomplete picture, because liquid CO2 is being
used in everyday practice as a dry-cleaning fluid. EG,

You need several atmospheres of pressure to get above the triple point of
CO2 - somewhere between 5 and 6 if memory serves.

You remove the good out of solvent whilst the bad is
suspended/dissolved. You are then left with a clean good and solvent
plus bad which you either discard or clean up for reuse.

One of the Stain Devils (the one for 'chewing gum, and glue') is excellent
at getting off sticky residues,as well.

Liquid butane and propane eh?

Why do you persist in posting utter crap about things which you really
don't understand?

What's wrong with butane - particularly in cold weather? At least you don't
have to wait ages for it all to evaporate away.
