Sodium dithionite
Not realy, since the dithionite percipitates S when mixed with water, especially when heated.

Safty in making large quantities of Copper Acetylide
Are you planning to do Reppe chemistry, since Cu2C2 is uesed there as a catalyst

H2O2 + NaHSO4
The H2O2 decays into O2 and H2O using the MnO2 as a catalyst.

Thorium chloride extraction.
Can´t you just reduce it with lets say Mg powder like:

ThO2 + 2 Mg --> Th + 2 MgO ?

Thorium chloride extraction.
No, since you will form ThO2 wich is very inert.
It´s only shlightly soluble in hot conc. H2SO4.
