butene-1 has a wide range of applications and market demand is constantly being released

butene-1 is one of the isomers of butene. at normal temperature and pressure, butene-1 is a colorless, flammable gas that is soluble in water and can be used as an anesthetic at high concentrations. according to different product purity, butene-1 can be divided into purity 99.3% and purity 99.0%. as an important basic chemical raw material, butene-1 can be used to produce lldpe, hdpe, poly-1-butene, dodecene, 1-octene, butyl mercaptan, n-butyl oxide, sec-butanol, etc. a variety of products, the nstream applications involve packaging, medicine, pesticides, wires and cables, films and other fields.

butene-1 mainly includes two production routes: the dimerization process using ethylene as raw material and the separation process using c4 fraction as raw material. butene-1 in my country is mainly produced by the c4 separation process. my country’s butene-1 industry research started in the 1990s. after years of development and accumulation, the scale of my country’s butene-1 industry has continued to expand. in 2020, my country’s butene-1 production reached about 670,000 tons, and the consumption was about 700,000 tons. at present, there is still a certain supply gap in my country’s butene-1 market, and the supply channel for the gap is to import products from south korea, qatar, india and other countries.

according to the “2022-2027 china butene-1 industry market in-depth research and development prospects forecast report released by the industrial research center , globally, the butene-1 market is mainly concentrated in north america, china and the middle east. in 2020, the total global butene-1 production capacity is about 3 million tons, and the production capacity mainly comes from ethylene cracking units. thanks to the release of nstream market demand, global butene-1 production capacity will continue to grow in the next three years, and is expected to reach 3.52 million tons in 2024.

in the international market, butene-1 suppliers mainly include sabic, of germany, iran npc, tpc group of the united states, exxon mobil, sumitomo chemical and other companies; in the domestic market, sinopec and petrochina are butene-1 1 main manufacturing enterprises, other enterprises such as sinochem quanzhou, henan longrun tianxiang chemical, feihong chemical, shenhua group, etc. also occupy a certain market share. with the improvement of production technology, my country’s butene-1 industrial structure is continuously optimized, and product quality and economic benefits have also been improved to a certain extent.

from the perspective of nstream application scale, due to factors such as raw material sources and technology, lldpe and hdpe are the main consumption scenarios of butene-1 in my country, followed by poly-1-butene. however, in the international market, developed countries mostly use high-carbon α-olefins such as 1-hexene, 1-octene, etc. to replace butene-1 as a comonomer. the proportion of butene-1 as a comonomer has dropped to 30 %the following.

industry analysts said that butene-1 is an important basic chemical material that can be used to produce a variety of chemical products. in recent years in recent years, with the continued release of nstream market demand, my country’s butene-1 industry has developed rapidly. while the scale of the butene-1 industry has expanded, the industrial structure has also been continuously optimized. from the perspective of production technology, butene-1 in my country is mainly produced by the c4 separation process, while in the international market, butene-1 production capacity mainly comes from ethylene cracking units.
