What are the main production routes and downstream applications driving sodium thiocyanate demand in China?
China's sodium thiocyanate market is segmented by production methods—synthesis and extraction—with applications spanning chemical intermediates, pesticides, construction, rubber, and analytical reagents. The synthesis route dominates, leveraging byproduct streams from coal chemical and coking operations. A notable development is the shift from ammonium-based to sodium-based salt extraction in desulfurization waste liquid treatment, as seen in projects like the Huangling Coal Chemical upgrade. This innovation converts previously unusable mixed salts into valuable sodium thiocyanate, addressing environmental concerns while creating economic value. Downstream, acrylic fiber spinning remains a key consumer, alongside growing use in pharmaceuticals and agrochemicals. Capacity expansions and technical upgrades are expected to improve product purity and reduce production costs, supporting market growth through 2029.
