SDK Expands Allyl Alcohol Production Capacity

Showa Denko K.K.
May 22, 2008

Showa Denko K.K. (SDK) has expanded its allyl alcohol production capacity at the Oita Petrochemical Complex from 56,000 tons a year to 70,000 tons a year.

Demand for allyl alcohol is growing as raw material for perfume, pharmaceutical intermediates and allyl ester resin (used in spectacle lenses). SDK developed a proprietary technology to produce allyl alcohol directly from propylene and acetic acid, and completed a plant based on the technology in 1985.

In view of the steady expansion of the business, SDK increased the production capacity to 56,000 tons a year in 2006. This time, SDK has further increased the capacity to strengthen its position as a leading allyl alcohol producer in Japan.

SDK is producing a variety of “acetyl chain” products at the Oita Petrochemical Complex based on an integrated production setup from naphtha feedstock and proprietary catalyst/process technologies. SDK will further enhance the efficiency of catalysts, develop new derivatives and increase the production efficiency of existing products. Thus, SDK will continue to increase the added value of its “acetyl chain” products while aiming to establish the Oita Petrochemical Complex as one of the most competitive complexes in Asia.
