‌Tertiary dodecylmercaptan (TDM)‌ is an important mercaptan product with a wide range of uses, including the following aspects:

‌Polymer polymerization regulator‌: Tert-dodecyl mercaptan is mainly used as a chain transfer agent in free radical polymerization, which can adjust the molecular weight of the polymer and make the molecular weight distribution more uniform. It plays an important role in the preparation of rubber emulsions such as styrene-butadiene rubber and nitrile-butadiene rubber. It is also used as a regulator in the numerical polymerization of styrene series such as ABS resin, and in the molecular weight regulation of special engineering plastics‌12.

‌Lubricating oil additive‌: Tert-dodecyl mercaptan can be used as an additive for lubricating oil, which can improve the performance of lubricating oil, reduce mechanical wear and extend the service life of equipment.

‌Nonionic surfactants‌: Tert-dodecyl mercaptan can also be used to synthesize nonionic surfactants, which are widely used in personal care products, food processing and other fields.

Organic synthesis, bactericides, anti-rust agents‌: Tert-dodecyl mercaptan is a raw material for a variety of chemicals, including organic synthesis, bactericides, anti-rust agents, etc. These products are widely used in agriculture, medicine, industry and other fields.

‌Paper coating slurry additives‌: In paper coating compositions, tert-dodecyl mercaptan can be used as an additive to improve the performance of the coating slurry and improve the quality and durability of the paper.

‌Stabilizer and antioxidant for polyolefins‌: Tert-dodecyl mercaptan can also be used as a stabilizer and antioxidant for polyolefins to improve the stability and durability of polyolefin materials.

In summary, tert-dodecylmercaptan has important application value in many fields and is a multi-functional chemical‌
