China and Germany are the leading exporters of Diketene, collectively accounting for a majority of global shipments, while the United States, India, and South Korea represent the largest importers. Diketene prices have remained relatively stable amid steady cross-border flows, reflecting consistent demand from pharmaceutical and agrochemical manufacturing sectors. Recent trade data shows modest growth in exports from China and increased import volumes in Southeast Asia, indicating expanding regional downstream production capacity.
Diketene is a colorless to pale yellow, volatile liquid with a pungent, acrid odor; it has a boiling point of approximately 101 °C and solidifies below −45 °C. It is a reactive cyclic ketene dimer and classified as a highly reactive organic chemical intermediate. Diketene serves primarily as a building block in the synthesis of acetoacetate derivatives—including acetoacetic ester, arylidene acetates, and heterocyclic compounds—through reactions such as acylation and condensation. Its principal applications are in the production of agrochemicals (e.g., pyrethroid insecticides), pharmaceuticals (e.g., anticoagulants and anti-inflammatory agents), dyes, and specialty polymers and coatings.
Chemical intermediate for acetoacetic esters & acetoacetanilides, n,n-dialkylacetoacetamides, dyes, pharmaceuticals, for pigments & toners, food preservatives, insecticides, dicrotophos, & the fungicide, dehydroacetic acid.
