Production

Synthesis

dimercaprol

  1. Combine 2,3-dibromo propanol with sodium hydrosulfide
    {{#Chem: C3H6Br2O + 2NaSH = CH2SH-CHSH-CH2OH + 2NaBr}}

sodium hydrosulfide

  1. Bubble hydrogen sulfide through a solution of sodium hydroxide which possibly contains some amount of solid sodium sulfide ({{#Chem: Na2S}}).
    {{#Chem: H2S(g) + NaOH(aq) { = 130-150°C } NaSH + H2O // gas can contain un-oxidized hydrocarbons in almost any amount }}[1]
    {{#Chem: H2S(g) + Na2S(s) { H2O = 95-150°C } 2NaSH(aq) }}[2]
