The haloform and hofmann hypohalite degradation both share the use of hypochlorites, but they are different reactions.
The haloform uses calcium (or sodium, etc) hypochlorite with a methyl ketone to form a carboxylic acid salt and chloroform. Thus MEK gives sodium propionate and chloroform.
The sodium propionate is acidified and the propionic acid distilled off for recovery.
If the amide of the propionic acid (propionamide) is made, then more hypochlorite can react with it to induce the hofmann hypohalite degradation, forming ethylamine and CO2 gas.
As long as you dont pay through the roof for hypochlorites, and as long as you dont need tons of ethylamine, this is a good route to this compound with OTC chemicals.
