The haloform reaction is used to prepare chloroform in a simple procedure. The resulting crude product is dried, distilled, and stabilized, giving an overall 66.5% yield from hypochlorite. A later batch using 4 of these bottles with proper chilling to -5C gave an average of 73.0% yield (bottles were also cooled faster following the reaction by placing outside in near-freezing rain). A discussion of the reaction mechanism follows. The intro music clip is from "Stealing Fat" by The Dust Brothers. I believe this falls under fair use.
