 Out of curiosity, "how hot" do you think, that , or a similar reaction would be, and how concerned should one bee about 'Thermal Shock' shattering the reaction vessel when placing it in the ice bath?

Some borosilicate glassware is better than other company's work, so that question is impossible to answer  ::)  The well prepared chemist has fans for cooling purposes as well, ghetto style chemistry is inherently far more dangerous  :o  The end results from the effort applied   8)

"so that question is impossible to answer"  But surely the "well prepared chemist" wouldnt be so stupid to "find that out" in the situation described above......

 I thought to some degree, WE are All "ghetto style" if the OTC theme  of this site IS relevant.....

"The end results from the effort applied"  I'll agree with this,, but I dont think

telling " ANYONE,, "well prepared" or otherwise, to just plonk your runaway in a

"Tub of icewater"  UNLESS specificaly called for in a rxn --

doing so IS inherently Dangerous!!! ergo sum: To Be avoided,, NOT 'suggested'

As far as borosilicate glass, there's an article on Wikipedia:

h**p://en.wikipedia.org/wiki/Borosilicate_glass

which is apparently too much effort to find without an extremely busy staff member posting a link  ::)  As far as whether cooling baths should be used to deal with runaway reactions, fortunately that's up to the reader to decide   ;D  Perhaps someone else will provide you with the answers you seem to want as far as thermodynamics  :P  The second law of thermodynamics is still accepted by the scientific community and that's not likely to change anytime soon  8)

= not getting what you want , getting even more pissed off and pissing everyone you shout and moan at off .  Tailor your comments on the results you want to achieve or shut the fuck up ....... please ........sir .......

Twenty eight members have downloaded a zip file called LabAccidentPrevention:

http://127.0.0.1/talk/index.php/topic,401.msg11671.html#msg11671

uploading which information seemed appropriate considering the title of this thread  ;)  Perhaps that information escaped notice, doing that would bee considered a lack of effort on the Hive  ::) As far as that phrase the end results from the effort applied, there was a member of the Hive called Jacked who had a signature: The end result is directly connected to the effort applied that was rephrased as a matter of respect for the Ancient Alchemist Deluxe  :-X  For those that don't know, there's a vast difference in quality between the glassware products sold by Bomex and Schott  :P  The old saying that applies in this case is you get what you pay for  8)

The advice that was offered to Methyl Man obviously got you upset, but indulging in personal attacks in a harm reduction thread is no place to express it  ::)  The obvious fallacy in your reasoning is that Methyl Man is the author of the procedure, and he wasn't aware of the incredible violent exothermic nature of the reduction of nitromethane once caustic soda was added  :P  Exothermia is very dangerous, and telling members not to bee prepared for it is ignorant at best and quite possibly malicious  :o  As has been stated before on the Hive in similar circumstances, we don't need any help in deciding what we should post  8)

"the end results from the effort applied"

I think we should all aply that to what we write and compaire what we want to achieve to what we do achieved and if we didnt achieve what we want adjust our writeing to better get the results we want .

Aye, its true.

Garbage in, garbage out.

Once upon a time a long ways from home, someone who will bee called not-lugh tamed a runaway al-hg with the proverbial wet blanket using fans to provide cooling via evaporation  ::) The runaway al-hg was caused by a bonehead who cut corners and bought regular thickness aluminum foil instead of the specified heavy duty Reynolds Wrap  :P  The bonehead ran away once the reaction starting climbing up the condenser, but not-lugh tamed the runaway exothermia  ;D  The moral to this story is that those that can save the day will do so, while those that want to indulge in arguments on the internet always want the last word  :(  This web site is for helping our members whenever possible  :-X  This argument is useless and off topic so it is being moved to Vacuous Posts where it belongs  8)
