The development history of petrochemical industry

• Petroleum refining began in the 1920s

① 1919 Mobil produced isopropanol from propylene - the first petrochemical product

• In the 1930s, a large number of polymer synthetic materials came out

① 1931 Neoprene and polyvinyl chloride

② 1933 High pressure ethylene production

③ 1935 nitrile rubber and polystyrene

④ 1937 Styrene Butadiene Rubber

⑤ 1939 Nylon 66

• The development of cracking technology in the 1950s provided a large amount of fuel for petrochemical industry

① 1953 polyester

② 1957 Polypropylene

• In the 1970s, the development of new processes was slow, and new technologies were adopted, energy-saving, and production operations optimized

Comprehensive utilization of raw materials to extend the development of downstream products
