What is driving new capacity additions for 1,2-dichloropropane in China?
China's 1,2-dichloropropane supply landscape is shifting as several new projects come online. Hubei Jiarun Chemical is building a 20,000 t/y unit alongside 40,000 t/y of 1,2,3-trichloropropane and 10,000 t/y of dichloropropenes in Yunmeng, Hubei. Shandong Sanyue Chemical plans a 12,000 t/y plant in Wudi using DD mixture feedstock from epichlorohydrin byproduct streams. These projects reflect a broader trend of valorizing chlorination byproducts into higher-value downstream chlorinated solvents. Most output will feed solvent applications in paints, inks, and PVC adhesives, as well as pesticide intermediates. With multiple capacities slated for 2025-2026, the domestic market could face oversupply pressure unless export demand for this UN1279 Class 3 flammable liquid expands correspondingly.
