Abstract
Stable S,S,S-tributylphosphorotrithioate having reduced levels of the odorous by-product dibutyl disulfide is produced by adding a caustic solution having a concentration of less than 10% to crude S,S,S-tributylphosphorotrithioate until the pH remains constant. In a preferred embodiment, a solution of sodium hydroxide having a concentration of less than 10% is used in an amount such that at least 0.1 mole of sodium hydroxide is present for each mole of crude S,S,S-tributylphosphortrithioate.
