Chloroform without bleach

Would decarboxylating Sodium trichloroacetate at high temperatures create chloroform with OTC* reagents? This would avoid using gallons of bleach to make 10ml of chloroform.
* In some places, Trichloroacetic acid can be bought for skin care

Use bleaching powder instead of bleach. Bleaching powder is made of calcium hypochlorite Ca(ClO)2, which usually contains also some CaCl2. But this impurity does not disrupt the action of calcium hypochlorite on acetone. And you don't need gallons of liquid to do it.

But that doesn't answer the question, would this work? It would be a nice way of making fluoroform too, assuming you can get trifluoroacetic acid. And also, can't the trichloroacetic acid be converted to the trifluoro version with sodium fluoride.

I believe Chemplayer made a video of the preparation of chloroform from trichloroacetic acid. However, the later is not exactly OTC and is considerably more expensive than either bleach, bleaching powder or acetone. If you happen to have a large drum full of trichloracetic acid then you can simply distill it and obtain chloroform.
