Daicel Chemicals Japan Ethyl Acetate Expands Energy by 50%

Japan’s Daicel Chemical Co., Ltd. recently stated that due to the recovery in demand for electronic and ink solvent applications, the company decided to expand its domestic ethyl acetate capacity by 50%. At present, the company is building a new 25,000-ton/year plant in Otake, Hiroshima Prefecture, Japan, and plans to put it into commercial operation in December 2011. By that time, the company's ethyl acetate production capacity will increase from 50,000 tons/year to 75,000 tons/year. As the global economy recovers, the use of ethyl acetate in the printing inks, adhesives, coatings, and electronics industries continues to increase.
