  • Friable tertiary amyl phenol sulfides as vulcanizing agent
    Patent number: 3992362
    Abstract: Tertiary amyl phenol sulfides are made in flaked form by reacting tertiary amyl phenol with sulfur monochloride at a mole ratio of 0.7 to 0.95 moles of the phenol to one mole of sulfur monochloride. The hot liquid reaction product is then flaked on a cooled surface. The use of tertiary amyl phenol sulfides as a sulfur donor in the vulcanization of rubber is facilitated by its ease of shipping and handling in flaked form.
