ABSTRACT:
Tri-n-butylphosphorothioite is produced on a continuous or semi-continuous by simultaneously adding phosphorus trichloride and butylmercaptan to a reaction vessel at a rate such that an excess of butylmercaptan is present and allowing the resultant mixture to react at a temperature of from about 120.degree. C. to about 150.degree. C. One or more reactors may be employed. This process is particularly advantageous for safety reasons and produces high quality phosphite which may be oxidized without purification to produce S,S,S-tri-n-butylphosphorotrithioate.
