What is it with the rediculous markup on chloroform?

I have one source that will sell 500ml for around £45, IMHO that is totally rediculous, I have a source for dichloromethane very cheaply, could it perhaps be chlorinated to yield chloroform?

Also, has anyone here tried the synthesis from acetone, using trichlorocyanuric acid/NaOH, what were the ratios used, and what were the yields like if anyone has tried this?

I read that synthesis from acetone using NaOCl gave lousy yields, and needed the NaOCl to be in VAST excesses for the reaction to proceed.

I would much prefer to produce my own chloroform, starting from acetone, as 5 liters of acetone is dirt cheap, just a few pounds, drying with MgSO4 to give anhydrous acetone is cheap also, price is a big thing for m in my experiments so I think this is the best way to aqquire my chloroform.

So anyone here got experience with the acetone/TCCA/NaOH chlorination?

Thanks.

We can get 4L of Chloroform for 20-30 dollars.

By the way, drying acetone with magnesium sulfate can be problematic because it can cause the acetone to polymerize.  A better drying agent is calcium sulfate (Drierite).
