Tetramethyl-monopentene needs to be broken through and the market prospect is broad

Tetramethyl-pentene, also known as 4-methyl-1-pentene and 1-isohexene, is a propylene dimerization product and an important branched α-olefin. Tetramethyl-pentene can be used as a comonomer of linear low-density polyethylene (LLDPE), and can also be used to prepare new polyolefin materials with outstanding optical properties, mechanical properties, high temperature resistance and electrical properties through homopolymerization. Phenyl monopentene (PMP). In addition, tetramethyl-pentene is easily and selectively isomerized into 4-methyl-2-pentene and 2-methyl-2-pentene, which can be used to produce isoprene.

China has invested relatively little in the field of tetramethyl-pentene and has few relevant research results. Due to weak technology accumulation, domestic industrial production has not been achieved. In terms of application, domestic research results are also relatively limited. In June 2020, Qilu Petrochemical Research Institute synthesized polytetramethylpentene in the laboratory for the first time, becoming an important domestic breakthrough in related technologies in this field and thus solving the “stuck neck” problem. Results.

According to the released“China Tetramethylpentene Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028”, Tetramethylpentene has high technical barriers. Currently, only a few companies in the world have technical reserves, but only one Japanese company, Mitsui Chemicals, has truly achieved large-scale production (British Petroleum once had a 2,000-ton device, but later due to various reasons to stop). The original Phillips Petroleum Company (later merged with Conner Petroleum Company of the United States and split into Phillips 66) once built a 10,000-ton tetramethyl-pentene unit in the 1980s. However, due to limited market demand and insufficient product competitiveness and other factors, the device has been discontinued.

From a market and policy perspective, tetramethyl-pentene is mainly used in the fields of linear low-density polyethylene and polytetramethyl-pentene. Among them, polytetramethyl-pentene is used in medical, wire and cable, electronic and electrical, etc. It is widely used in many fields and is the largest and most concentrated downstream field of polytetramethyl-pentene consumption. In the future, with the optimization and upgrading of China’s industrial structure and the increase in the application of high-end materials, China’s demand for polytetramethyl-pentene will continue to grow. The acceleration of the transformation of research results will promote the industrial development of domestic polytetramethyl-pentene. As the main raw material for the production of polytetramethyl-pentene, the demand for tetramethyl-pentene will also increase accordingly.

Industry analysts said that the country has vigorously developed policies for special polyolefins such as metallocene polyethylene and key raw materials such as high-carbon alpha olefins. Under the call, more research resources and funds will enter the field of tetramethyl-pentene and promote the development of tetramethyl-pentene and related industries. China’s tetramethylpentene and its related industries have great potential for development. In the next few years, with the development of China’s economy and the growth of demand for high-end materials, the demand for domestic substitution of tetramethyl-pentene and polytetramethyl-pentene will become increasingly strong. Domestic substitution will provide a broad market space for the development of the local tetramethyl-pentene industry.
