| titleOfInvention | Process for producing stable, low odor S,S,S-tributylphosphorothrithiote |
| abstract | The invention is directed to a process for producing a stable, low odor S,S,S-tributylphosphorotrithioate having a level of dibutyl disulfide of 0.3% by weight or less. The process broadly includes the steps of a) reacting S,S,S-tributylphosphorotrithioite with an oxidizing agent to produce a crude S,S,S-tributylphosphorotrithioate, b) treating the crude product with sodium bisulfite to decompose any excess oxidizing agent, c) adding a caustic solution having a caustic concentration of from 25 to 50% by weight directly to the reaction mixture of step b), the addition of said caustic solution being stopped once the total caustic concentration is less than 10% by weight and once the pH is constant, and d) phase separating S,S,S-tributylphosphorotrithioate from the mixture of step c). |
