Epichlorohydrin: 58% of domestic production capacity is constrained, leading to a 40% price increase. China’s epichlorohydrin production volume amounts to 624,700 tons. The production capacity for this substance is mainly concentrated in Shandong and Jiangsu provinces; the three companies Hai Li in Shandong, Hai Xing in Jiangsu, and Jin Qiao Yi Hai together account for 550,000 tons of production capacity, which represents 58% of the total national capacity. At present, Shandong Haili’s 320,000-ton epichlorohydrin plant is shut down for renovation, and the time for its restart is still uncertain. The 130,000-ton plant in Haixing, Jiangsu is shut down, while the Jinqiao Yihai plant is operating at half capacity. Following the 321 explosion accident, strict measures have been continued in the Jiangsu chemical industry park, making it difficult to increase the level of operations there. “With stricter measures on energy consumption control, most areas in Jiangsu have implemented a policy of operating two facilities while shutting down two others; enterprises in Shandong have also received notices requiring power restrictions, resulting in a decline in their operational rates.
The main use of epichlorohydrin is in the production of bisphenol A glycidyl ethers. That is, epichlorohydrin reacts with bisphenol A in the presence of caustic soda to form bisphenol A chlorohydrin ether, and then hydrogen chloride is removed using caustic soda to yield bisphenol A glycidyl ether. Epichlorohydrin is primarily used in the synthesis of glycerol and epoxy resins; it can also be employed in the production of epoxy resins, chloroprene rubber, nitroglycerin**, fiberglass, pesticides, pharmaceuticals, surfactants, coatings, adhesives, plasticizers, reinforced plastics, and electrical insulating materials. It can also be used as a solvent for paints, cellulose esters, cellulose ethers, and resins.
