MIDLAND, Mich. - The Dow Chemical Company has announced that its wholly owned subsidiary, Union Carbide Corporation, will invest in new ethyleneamine capacity that will significantly advance Dow's ability to meet market demand for the two largest-volume ethyleneamine homologues globally and in North America - ethylenediamine (EDA) and diethylenetriamine (DETA).

Union Carbide will expand its existing reductive amination ethyleneamine unit at St. Charles Operations in Hahnville, La., and implement propriety amination technology in a new facility that will produce primarily DETA. The new facility and expansion are expected to be complete in mid-2007 and will provide Dow with a step-change improvement in product-mix flexibility and selectivity for EDA and DETA.
