Production Process of TBBS

TBBS (N-tert-butyl-2-benzothiazolesulfenamide) is a rubber accelerator that is widely used in the production of tires, rubber pipes, and other rubber products. The production process of TBBS involves several steps, including:

  1. Nitration: In this step, benzothiazole is nitrated to form 2-nitrobenzothiazole. The reaction is carried out using nitric acid and sulfuric acid as catalysts. The yield of this step is around 90%.
  2. Reduction: The 2-nitrobenzothiazole is then reduced to form 2-aminobenzothiazole using hydrogen gas and a nickel catalyst. The yield of this step is around 95%.
  3. Alkylation: The 2-aminobenzothiazole is then alkylated with tert-butyl chloride to form N-tert-butyl-2-benzothiazolesulfenamide (TBBS). The reaction is carried out in the presence of a base such as sodium hydroxide. The yield of this step is around 80%.
  4. Purification: The crude TBBS is then purified using a series of processes such as filtration, washing, and crystallization. The final product is a white to light yellow powder with a melting point of around 104-108°C.

The production process of TBBS is complex and requires careful control of reaction conditions to ensure high yield and purity. The use of advanced technology and equipment has enabled manufacturers to produce TBBS efficiently and cost-effectively.
