China’s tert-dodecyl mercaptan is mainly used in the field of ABS resin. Market demand is completely dependent on imports.

Tert-dodecyl mercaptan, also known as tert-dodecyl mercaptan, tert-dodecyl mercaptan, or TDM for short, is an important mercaptan product. It is mainly used to prepare styrene-butadiene rubber, ABS resin and nitrile rubber. Effectively reduce the degree of branching of the polymer chain, adjust the molecular weight, and make the molecular weight distribution uniform. At the same time, tert-dodecanethiol can also be used as a stabilizer and antioxidant for polyolefins, or for the synthesis of nonionic surfactants, lubricant additives, organic chemicals, fungicides, pesticides, etc.

In the field of industrial production, relevant companies mainly use dodecene low-temperature and low-pressure method to produce tert-dodecene mercaptan. This method uses dodecene as raw material and has simple process flow, high product yield, basically no side reactions, and good product quality. Features. In addition, relevant companies have also developed dodecyl alcohol high temperature and pressure method and dodecyl chloride method to produce tert-dodecyl mercaptan.

At present, the main producing countries of tert-dodecanethiol are the United States, France and South Korea. Representative companies include Chevron Phipps, Arkema and Lishu Chemical. In the early days of our country, tert-dodecyl mercaptan equipment was built. However, due to factors such as increased environmental pressure, difficulty in obtaining raw materials, and limited downstream market demand, related companies withdrew from the industry. Currently, there are no domestic manufacturers of tert-dodecyl mercaptan products. , the market demand for tert-dodecanethiol is completely dependent on imports. From the perspective of import volume, from 2018 to 2022, China’s import volume of tert-dodecyl mercaptan continued to increase due to the increase in downstream demand for ABS resin, styrene-butadiene rubber, etc. Among them, in 2022, domestic imports of t-dodecyl mercaptan will exceed 20,000 tons.

From the perspective of downstream applications, according to the “In-depth Market Research and Development Prospects Forecast Report of China’s Tert-Dodecane Mercaptan Industry from 2023 to 2028” released by the Industrial Research Center It shows that at this stage, my country’s tert-dodecyl mercaptan market consumption is limited, and it is mainly concentrated in the field of ABS resin, with few applications in styrene-butadiene rubber, nitrile rubber and other fields. In the future, with the development of automobiles, home appliances, consumer electronics and other industries, the production scale of my country’s ABS resin industry will continue to expand. It will still be the main application field of tert-dodecanethiol, and the consumption share of ABS resin is expected to further increase. .

Industry analysts said that for a long time, the tert-dodecanethiol product market has been dominated by American Chevron Phipps and Korean Pear. Occupied by three companies including Tree and French Arkema, a monopolistic market structure has been formed. It is expected that in the coming period, even if new companies enter China’s tert-dodecanethiol industry, the overall competition pattern of the industry will not fundamentally change. Key companies such as Arkema, Chevron Phillips Chemical, and Lishu Chemical will still be in the leading position. But in the long term, as local Chinese companies break through relevant core technologies and realize the industrialization of tert-dodecanethiol, local companies may occupy a certain market share in the domestic market by virtue of their localization advantages and product cost-effectiveness advantages.
