Does anyone know how soluble iodine is in DCM

I can't find a X amount of iodine in grams is soluble in X amount of DCM.i can find information on benzene,chcl3,ccl4 etc but not DCM.apparently chcl3 is about 50g/kg which isn't much.if anyone knows if it's more or less soluble than that it would help.

Well, that took 30 seconds...

Solubility: the solubility of iodine, expressed in g/kg of solvent at 25 °C is: H2O, 0.34; benzene, 164.0; CCl4, 19.2; CHCl3, 49.7; ethyl acetate, 157; ethanol, 271.7; diethyl ether, 337.3; n‐hexane, 13.2; toluene, 1875.12 Soluble glacial acetic acid; relatively insol dichloromethane.

Sight I seen the same info ended after the first 4 solvents.

Thanks though that clarifies my current idea needs rethinking

So, it took you just 30 seconds to fail to answer the question. Congratulations!

I spent a little more time on it and I'm afraid I didn't find any useful data (on the solubility or the partition coefficient).

It's possible that this sort of thing would let the OP extrapolate from the other data.

Not really, but whatever...

I must have missed it.
What's values of X did you give in response to the query "I can't find a X amount of iodine in grams is soluble in X amount of DCM"?
