Information @ a Glance


  • Diketene is an organic compound formed by dimerization of ketene. Diketene is a member of the oxetane family. It is used as a chemical reagent in organic chemistry. It is a colorless liquid and heating regenerates the ketene monomer.
  • Diketene is produced
    by dehydrating acetic acid at a temperature of 700 to 750 degree celcius in the
    existence of triethyl ether as a catalyst. The other method for manufacturing
    diketene is by thermolysis of acetone at a temperature of 600 to 700 degree celcius
    in the presence of catalyst such as carbon disulphide. Some of the diketene
    derivatives include acetoacetates, arylamides, alkylamides, acrylic acid esters and other diketene derivatives.
  • According to statistics, China has 22 diketene producers with an annual capacity of more than 20 000 tons and an output of 12 600 tons. The biggest producer is Nantong Acetic Acid Chemical Plant having an annual output of around 2 500 tons and more than 20 varieties of derivatives. Quite a few pharmaceutical and pesticide plants have set up diketene units to produce derivatives for their own use. There has been a great increase in these two years in both varieties and quantities of diketene series. The domestic demand of diketene today is estimated to be around 10 000 tons, 50% to the pharmaceutical industry and 40% to the pesticide industry.
  • The global output of diketene is around 100 000 tons a year today. Major producers include UCC, Eastman and FMC of the United States, Hoechst of Germany, Celanese of Britain, Lonza of Switzerland and Synthetic Chemical Industry, Daicel Chemical Industry and Teijin Shoji Co., Ltd. of Japan.
  • The strong growth in the pigment industry in the
    developed countries such as U.S. is expected to cater demand for diketene in the
    market. The developing country such as the Asia Pacific has huge growth potential for the pharmaceutical industries and hence is anticipated to boost demand for diketene. China has huge production facilities for diketene and hence it consumes huge amount of diketene for a wide variety of applications.
  • Global ketene consumption will grow 2–3% annually during 2012-2018. The main drivers of this growth will be China and India. China is expected to have additional acetic anhydride and sorbic acid production, while India is expanding in diketene derivatives
