News / Re: DEA To Update Watched Chemicals List To Include Sodium Borohydride

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

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

Honestly kind of overcomplicated when you can just buy the best precursor to borohydride and react it with alkali hydroxides
What's the precursor?

I'd be interested to know as well, because I was under the impression the easiest for the amateur would be sodium hydride and trimethyl borate. I was thinking borane and sodium hydroxide, but I am fairly sure that would produce sodium metal.

Not sure I understand the fuss about nabh4 being watched, the time spent figuring out how to get or make nabh4 could be better spent figuring out how to reduce without it

There was this chinese patent, the NaBH4 was made from Mg metal and some borax sodium carbonate, water in a ball mill: https://www.sciencemadness.org/whisper/viewthread.php?tid=158235

 One would have to make a tightly sealed ball mill, that could bee filled with argon though and afterwards wind a way to recrystallise the NaBH4 without hydrolysis. Quite a bit of a hassle and specialised equipment.

Various new users are spamming this board with nonsense, all likely just bots. god knows what reason someone would waste their time doing so, but indeed it is occurring.

Please promptly execute these braindead larvae and chemically destroy their remains so our humble vespiary will be clean of their unwelcome filth and nonsensical tomfoolery.

Many thanks <3 (Also delete this post if you wish once the task is completed)

It's gonna be fine Java, last time that happened it was up after a day or two if I remember correctly. The legacy will not die ;). Way too many people involved in this!

.....its been a while now, but some changes over at Sciencemadness have caused the forum to go off line just too often,...Polvorone had always kept it on line, but with changes in administration many things have changed shadows of Sauron  and changes in internet server...whatever the cause, it seems changes are here to stay.......java
