| titleOfInvention | Process for hydrocarbyl trisulfide product |
| abstract | A method for preparing an essentially chlorine free additive mixture for oleaginous fluids containing less than 15 wt. % dialkyl higher-polysulfides, the process comprising: a) forming a reaction mass comprising olefin, a sulfur source, and a catalyst; b) heating the reaction mass to a temperature and for a period of time which is sufficient to form a mixture of olefin, alkyl mercaptan, dialkyl disulfide, dialkyl trisulfide and dialkyl higher-polysulfides; and c) refluxing the reaction mass obtained in (b) at a temperature and for a period of time which are sufficient to convert at least a portion of the dialkyl higher-polysulfides to dialkyl trisulfide so as to obtain the additive mixture containing less than 15 wt. % dialkyl higher-polysulfides. |
