I have about a liter of old chloroform. I hate using it for extractions, because it smells horrible. Is there some way I could convert it to formaldehyde or some other useful chem? <br><hr> Split a piece of wood and I am there. Lift a stone and you will find me.

Chloroform is pretty damn inert. I don't know of any reaction that will turn it into any goody. But keep asking, because I want to know, too.<br><br>It will react with sodium ethoxide to form NaCl, EtOH, and dichlorocarbene, which will add to alkenes and all kinds of other shit. It's a really cool reaction, but too bad it doesnt produce ANYTHING useful to us, just damn dichlorocyclopropane derivatives with those alkenes, and only God knows what crap with other compounds.<br><br>If not made in situ with something else, it will condense to tetrachloroethene (Cl2C=CCl2) but I wonder if the dichlorocarbene will react with this double bond to form the hexachlorocyclopropane? I've always wondered this...<br><br>In any case, good luck Bwiti.<br><br> PrimoPyro<br><hr><font color="blue"><i>Vivent Longtemps la Ruche!</i></font color="blue">

It is good for reimer-tiemann formylation of phenols. Phenol + CHCl3 + NaOH => Hydroxy-benzaldehyde.

I am currently trying to dig up more information on the use of chloroform in the synthesis of Mandelic Acid (P2P intermediate) by action of potassium carbonate upon a heated mixture of benzaldehyde and chloroform.<br><br>Also a nice little sleep aid can be easily made called trichlorobutanol from chloroform.<br><br>Can't find any simple conversions to formaldehyde though, only conversion to formic acid(formate)

"To produce a formate, hypochlorite must be heated with ethanol."<br><br> Well, if formic acid ever becomes difficult to obtain without having a 9mm put to my head, then I'll keep that in mind..Hmmmm, what would be created if a hypochlorite was heated with methanol or isopropanol? This is almost as fun as imagining all the materials one could reduce with Al/Hg.<br><br>"did the bear manage to get any honey out of the raw plant material that was left?"<br><br> He ate the leave buds raw and made a tea from the stems, which got him a little altered, but the short-term future is fucked. After christmas, the bear's hell-bent on growing 100% indicas, which will be a mix of several strains, uncluding a hash producer. He already has a new sheet of glass; it's security glass, so it'll crack, but it won't fall apart. The bear is very worried, because Capt. K-hole hasn't returned from canada yet! Hope he didn't get busted! Btw, sometime in the future, the bear will send your dream character some purple leaves and buds.
