      sulfur containing mbrp? could lead to H2S?     

Dose anyboy know someting about sulfur containing mbrp, the problem is that sulphur is like RP non polar. I cannot get rid of S with acetone and Water washing.
The danger that it could could lead to H2S: 2HI + S + delta temp -->H2S + I2 and H2S is deadly toxic.
P.S: I have alredy used TFSE®

      Phosphorus pentasulfide     

If the match head has sulphur, S it will react with RP to form Phosphorus pentasulfide. However, the reaction between RP & I2 will predominate.

Not sure? From memory recall I think they are potassium chlorate + Phosphorus pentasulfide.

It seems that a hybred H2S reduction and HI reduction could be done using strike all matches found anywhere in the world if the favors HI reaction good vent condenser outside to rid reaction of unused H2S.

Wizard X you posted a stink bomb method of ephedrine reduction,it seems maybe a dash NH3OH in the cook would make best use of the strike all matchheads.

nightshade: I didn't post the stinkbomb method, but I did post the H2S reduction of ephedrine.
