Errrm dude, if you dont understand whats being talked about, shut up (unless i missed a smiley of course),-Shrub

Yeah to bad Ive tried crazy **** like this before like use a oxy-acteline tourch then dropping it in dry ice (frozen Co2)...... It blew threw concrete 4 inches thick. So Shrub ask before you run your mouth!!

And anyone who thinks they do crazy **** PM me and ill tell you how/if I did it

anyone who messes with acetone and a red hot object be prepared to jump back quick as in light the fuse and run.

I honestly don't think it would be a problem as long as there was plenty of the dry ice in the bowl. Even though acetone has a very low boiling point, the dry ice would keep it virtually all liquid. With the massive volume of gas from the sublimation of the CO2, as far as inflammability is concerned, it is an inert environment.

That would be true in a sealed environment, but the gas of Co2 is denser than air so it will sink toward the ground. Since acetone vapor is lighter than air it will rise, thus(if somthing red hot will ignite it) it will burn because the Co2 vapor will not affect the fire at all.

If this is being done in a bowl like I suggested, the CO2, as you pointed out, is heavier than air and will fill the remainder of the bowl...

I have done this procedure before with smaller parts and it was fine. My real concern with a padlock is the extra size contributing to more Heat and more surface area for that Heat.

It all depends on the volumes of each... smaller lock into bigger bowl = the better.

Please keep in mind that the vapor pressure of acetone at -78.5C is 0.16mmHg compared with 229.52mmHg at 25C. So, the risk of fire from vapor at dry ice temperatures is rather minimal. However, it isn't zero.

Ethanol (denatured alcohol, EtOH, happy funtime juice) has a vapor pressure that isn't measurable to two decimal places at dry ice temperatures, so it is the better choice, especially considering all the fun plastics acetone disolves.

(All bets are off if you have a hulking huge lock with an extremely high heat capacity and a quantity of dry ice bath that has a much lower heat capacity. Calculations are your friend)

However, the temperature differential between heating the lock with a propane torch/gas stove and an ice/water bath is more than sufficient to dissassemble the lock.

Ketones are so much more fun though. It's amazing the difference a single bond can make.
