DEA To Update Watched Chemicals List To Include Sodium Borohydride

<< < (6/6)

Mrbovinejony:
And why isn't this method used or talked about more? I see no cheap magnesium diboride or easy way to make it

Rawhide Kobayashi:
I read that the yields are very low like 10%, and isolating the pure borohydride without decomposition would be tricky.

Osmiridium:
There’s no guarantee that this is what atara was talking about, but it was all One could find.

atara:
Yeah I was talking about the MgB2 method. The yield is about 10% of the boron but considering the electronics that's around 40% of theory. So not awful. The nice thing about MgB2 is that it's basically completely stable and easy to store which helps make up for the huge excess.

I suspect you could get a better yield if you used a mixture of MgB2 and metallic Mg. That would improve the theoretical yield substantially.

The balanced equations:

2 MgB2 + 4 NaOH >> NaBH4 + 2 MgO + NaBO2 + 2B

2 MgB2 + 8 NaOH + Mg >> 2 NaBH4 + 4 MgO + 2 NaBO2

Using KOH instead might also increase the yield but the product KBH4 is less reactive and less soluble. No idea if it would still work for the CuCl2 bit.
