WACKER BIOSOLUTIONS, the life sciences and biotechnology division of the WACKER Group, is expanding its integrated ketene production at its Burghausen site in Germany. The company is building a new reactor for the manufacture of isopropenyl acetate (IPA), an important starting material for acetylacetone (AcAc), with an annual capacity of 2,500 metric tons. The expansion is part of WACKER's strategy to increase the proportion of specialties in its business and strengthen its position as a leading manufacturer of fine chemicals. In addition, WACKER is taking over the sales and distribution of calcium acetylacetonate from Acetonate GmbH.
