1-Hexene CAS 592-41-6 manufacturer & supplier in China

Prdocution outlook from China 1-Hexene manufacturer & suppliers
1-hexene CAS 592-41-6 is linear α- It is one of the important varieties in olefins, mainly used in LLDPE, HDPE, plasticizer and chemical intermediates. There are three production processes of 1-hexene, namely ethylene oligomerization, extraction and ethylene trimerization.

The ethylene oligomerization process can simultaneously obtain more than 10 olefins above c4-c20, which has the problems of low selectivity of the target product l-hexene and difficult product separation. The technology is owned by Chevron Phillips, shell, BP Amoco, Idemitsu, Ineos and other companies.

The extraction process is based on the rich oil obtained in the process of coal to oil α- The side line fraction of olefins can be recovered to high quality through certain reaction and separation α- Olefins. The main representative enterprise is Sasol in South Africa. With the development of China's coal to oil industry, Shaanxi future energy and other enterprises mastering independent extraction technology have emerged.

The purity, yield and selectivity of 1-hexene produced by ethylene trimerization process are higher than the first two. Since the discovery of this process in the 1970s, major petrochemical companies have up and studied it.

The comparision of 1-Hexene production methods
Until the end of last century, China had no 1-hexene production technology, and the products completely depended on high price imports, which seriously restricted the R & D and production of high value-added products in downstream polyolefin and other industries. At present, Sinopec Yanshan Petrochemical, Daqing Petrochemical and PetroChina Dushanzi Petrochemical have built a set of 50000 T / A, 5000 t / A and 20000 t / a 1-hexene industrial production units respectively, all of which adopt domestic ethylene trimerization process technology.

As a comonomer for the production of high value-added polyethylene, 1-hexene is widely used in polymer materials, fine chemicals and pharmaceuticals α- Olefin products are mainly used as comonomers for the production of high value-added polyethylene. The polyethylene produced by it has the advantages of high tensile strength, impact resistance, tear resistance, puncture resistance and high light transmittance. It is especially suitable for the production of packaging film, agricultural film and large-diameter pipe. With the increasing market demand for membrane materials and pipe materials, the use of 1-hexene is increasing. However, until the end of last century, there was no 1-hexene production technology in China, and the products completely depended on high price imports. Moreover, foreign manufacturers have been monopolizing 1-hexene at high price, which seriously restricted the R & D and production of high value-added products in China's polyolefin industry.
