[edit] theoretical bias

this is a pretty good article explaining the theory and modes of reflux. it seems as though it could benefit with a few examples of the reflux typs. what do others think? Anlace 20:42, 12 January 2007 (UTC)

Please elucidate what you mean by "examples of reflux typs". Did you mean types? What sort of examples ... in the text of the article or in images or photos or what? - mbeychok 21:09, 12 January 2007 (UTC)

Hi. not necessarily images or photos, but rather more specific examples (in the text) of solvents and chemical reactions or more specificity of applications. for example one area that comes to mind is the use of reflux to study metal decomposition in the presence of various solvents. much of the history of this research goes back to the 1960s. the research i am most aware of features aluminum reaction in the presence of trichloroethylene. research progress was at a standstill until refluxing was used to accelerate the time scale and allow study of many different solvents and additives. this research was quite important in the development of stabilizers for TCE and other commercial solvents.

I agree that a few brief examples of the use of reflux in reaction chemistry might be useful ... as long as the use of reflux in industrial and laboratory distillations doesn't get overwhelmed by too much content on reaction chemistry. The alternative might be to have a completely separate article on the use of reflux to supply energy to chemical reactions. Unfortunately, I've seen too many articles get involved in heated confrontations when they start trying to cover too many techniques or technologies in one article.

Anlace, changing the subject entirely ... why are you reluctant to use capital letters to start sentences ?? :) Regards, - mbeychok 07:00, 13 January 2007 (UTC)

cause i can type faster and have more time for substance in articles :). so far avoiding using caps in talk pages has saved me approx 45 minutes of my life. enough time to write a small article.^{[citation needed]} regards Anlace 17:39, 13 January 2007 (UTC)

[edit] Reason for reverting spelling changes by 212.32.125.85

Wikipedia policy regarding words that have alternative spellings is that the spelling used in the earliest chronological introduction of such words in an article shall be used in that article from then on.

The originator of this article used U.S. English spellings rather than British English spellings when choosing to use the words "vapor" and "flavor" in creating this article. That means that U.S. English spellings are always to be retained in this article. It does not mean that either spelling is "right" or "wrong". It simply means that it is Wikipedia policy. - mbeychok 14:22, 16 June 2007 (UTC)

[edit] Water Connections

Why is the "Water In" line always below the "Water Out" line? I've never really understood this.207.6.125.46 (talk) 01:10, 1 February 2008 (UTC)

Putting the water in at the bottom (and out at the top) allows the whole condenser to completely fill with water, and thus gives a more efficient cooling surface. If you add the water from the top, then the water can simply gush out the bottom without necessarily filling the whole condenser. This may even force the user to use a rapid flow of water which is not necessary with a bottom filling method. There may be an extra advantage in that the coolest water contacts the vapour phase first. I've also had it suggested that having the water in at the bottom allows the water to be disconnected from the condenser more efficiently (i.e. the condenser empties more readily) when reflux is over, however, I'm not convinced this makes any odds, and in any event, it seems a trivial reason for insisting on such a filling method. -- Quantockgoblin (talk) 23:09, 1 May 2008 (UTC)
