Abstract: Oil-treated insoluble sulfur was prepared from environment-friendly rubber oil obtained from naphthenic vacuum side cut 1 distillate by hydrofining process, and its application performance was evaluated. The results showed that the oil-treated insoluble sulfur preparedby hydrofining processcould meet the requirements of EU 2005/69/EC regulation, andthe oil-treated insoluble sulfur prepared with this environmentally friendly rubber oil had excellent performance. This technology effectively expanded the application field of naphthenic vacuum side cut 1 distillate and realized the transformation of oil productto special chemicals.

Key words: environment-friendly rubber oil, insoluble sulfur, hydrofining process, vulcanized rubber
