I am going to leave my input. You could use sodium chloride, manganese dioxide and add concentrated sulfuric acid(drain cleaner kind) with a little
heat. You could try a higher temperature method replacing sulfuric acid with anhydrous sodium bisulfate. Another method I read about which may or
may not work is heating sodium chloride with sand and anhydrous magnesium sulfate to red heat. The later starts with dirt cheap reactants but
requires considerable heat input. I may try it on a 5 gram scale just for the science aspect.

clearly_not_atara They pressed it because they used samothing like an very big Kip Gas generator and the powder could get into the bellow tank and
releases to much chlorine. oh they soaked the MnO2 briks with little bit MnCl2 bevore the baking because they where more stable. Better procedur is
Weldon mud.
The MnO2 NaCl sulfruic acid need heating and you need lots of sulfuric acid
MnO2 +2NaCl + 3H2SO4 = MnSO4 + 2NaHSO4 +2 H2O+2Cl

this is a factor that I did not realise the significance of for many
years,
Scale matters!
When I first wanted jointed glassware I checked the options and costs of different glassware based on joint size.
At that time, and even now I think, neck size 24 (24/29 or 24/40) was the best buy.
Now most of my glassware is NS24.
So I typically use 100ml to 1000ml RBFs,
which means that I use 50ml to 500ml quantities per batch,
which means that I buy in 500ml or 500g quantities or more
(usually more to benefit from lower cost per ml/g and postage)
So I need a LOT of storage space for equipment, supplies and products,
and all hazardous chemical storage problems scale up as well.
So
I'm giving the same advice that I ignored when I started.....
work at small scale, unless it's for something spectacular.

I have the same problem. Same too with joints of glassware 29/32 arent cheap where i live .but chinese from vevor 24/40 you can buy 130 parts
destilling setup with 3 colums for 130 Euro.Bevor i could only by an bridge and 2 roundflasks for that money.
For chemicals sometimes you make big batches or precursors because every time to synthesis this to make that is an hasle.
