I have heard that magnesium perchlorate is an extremely good drying agent, but I can't find any chemistry book references on ways of making it.
Is Mg(CLO4)2 made the same way as potassium perchlorate is made, by heating potassium chlorate ?
Anybody got any good text book synths for me while I'll plough though the patent office site ?
One day I'll understand everything !
Couldn't you use ion exchange between MgSO4 and NaClO4?
NaX exchanges with lots of sulfates.
Guess who exceeded his alotted Hive bandwidth today?
would the sodium perchlorate not oxidise the Magnesium sulphate to a persulphate ?
Oh no that does not balance ! :P
Yes seems a great method ! :)

Is magnesium perchlorate a powerfull enough dehydrator to pull H2O's away from organic chemicals, like turning amide's into nitriles ?
One day I'll understand everything !
Still going for acetamide --> acetonitrile? :)
I don't know on the MgClO4. What about phthalic anhydride?

You can make P2O5 by heating a phosphate salt with sand (no carbon).

How hot?

No I'm not going for acetonitrile, I just used it as an example.
Just wanted to know just how powerfull a dehydrating agent magnesium perchlorate is.

>How hot?
Very hot. From what I can remember from reading about it, about the same temperatures as making phosphorus.

Don't use magnesium perchlorate as a drying agent. Organic materials in contact with magnesium perchlorate will spontaneously combust. Magnesium perchlorate is used as a drying agent only in a special case - the absorption train of an elemental analysis rig.
