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.

Harm Reduction Resources / Any moderators that see this, it's hammer time! Bots spamming this board.

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

News / New discovery regarding H2O ions.
« Last post by Shapeshifter32 on January 22, 2024, 10:58:04 PM »
     

     "Contrary to the long-held belief that ions form an electrical double layer, orienting water molecules in a single direction, the research demonstrates a completely different scenario.

Both positively charged ions (cations) and negatively charged ions (anions) are found to be depleted from the water/air interface.

More intriguingly, the cations and anions of simple electrolytes can orient water molecules in both upward and downward directions, overturning existing models"

I've been debating turning my pcl5 into thionyl chloride to avoid producing pocl3 when I need things chlorinated. The only reason I have to keep pcl5 is for vilsmeier which I haven't done in months

Personally, I would recommend keeping it as PCl5 and only synthesizing SOCl2 when you know you'll need it sometime in the next reasonable amount of time. It's a bit of a pain to purify the SOCl2 POCl3 mixture to perfection, but having SOCl2 handy when the time comes to use it is really nice. It is subject to photolysis and slowly degrades and is all around nasty stuff so I, too, prefer keeping PCl5 in storage than thionyl chloride.

The synthesis is very visually appealing though. Colorless gas + colorless solid -> colorless liquid. Very cool to see.
