Benzaldehyde/acetone azeotrope

kemm10 - 6-7-2007 at 00:10

Does anyone know if one exists?

Try looking it up in the Handbook of Chemistry & Physics, the Merck Index, Lange's Handbook, the International Critical Tables, and Perrys Chemical Engineers' Handbook, among others. From a thread I started in the References section, here is a partial list of links likely to have information on azeotropes:

(Also, uncompressed and without password, at http://rushim.ru/books/spravochniki/chemical-compounds.pdf , 37,227 Kb, but their server is frequently off-line.)

(Originally from http://rushim.ru/books/spravochniki/merck-index11.djvu , but their server is frequently off-line.)

There is now also a 13th edition of the Merck Index:

Someone else uploaded the International Critical Tables, of physical properties of compounds, including their variations with temperature, and phase diagrams, in April 2007, and the links are still current:

None of my references list one. Their boiling boints are quite far apart, it's not common to see azeotropes in that case unless there's some strong interaction between the substances. Even when there is azeotrope isn't almost always 98+ percent of one of the substances, which may work for steam distillation but general isn't useful.

Note that if you've water in the mixture, you can't ignore it.

I have the books "Azeotropic Data vol. I & II" published by ACS in 1952 & 1962 resp. This pair is not listed in those biooks.

@JohnWW: The above "Roempp"-link functioned, but the file is a nero-image; it somehow doesn't transform to a standard readable iso9660-image under linux ; ...

JohnWW - 17-2-2009 at 04:57

That would have to be due to the limitations of Linux. You will have to boot to Windows, and if you do do not have a recent version of Nero to handle the NRG disk image, find and use MagicISO or PowerISO to open or burn it.

These aren't working unfortunately.Someone (maybe you John?) uploaded as a single file in references but you need premium account status to download.

JohnWW - 18-2-2009 at 20:24

Those links were put up in 2007 by someone else. If you cannot download that 300-Mb upload of the ICT, try googling for other links with this search string:
"International Critical Tables" PDF OR RAR OR ZIP OR ISO "rapidshare.com/files" OR mihd OR ifile OR mediafire OR megaupload OR badongo OR torrent

This throws up 244 results, which should include currently available downloads of ir.
