The first crack in this paradigm, however, occurred in 1989. Although not commercially attractive from a conversion and reactivity point of view, Hoechst (1) and Henkel (2) demonstrated that alkoxylation catalysts based on alkali/alkaline-earth metals and calcined hydrotalcites (aluminium-magnesium hydroxy-carbonates), respectively, promoted the ethoxylation of esters. In 1990, Vista Chemical Company (now Sasol North America, Inc.) demonstrated that their proprietary catalyst (activated calcium and aluminium alkox-ides), and similar catalysts, efficiently and effectively ethoxylated a variety of esters (3). That same year. Lion showed that magnesium oxide-based catalysts also worked well (4). Henkel followed with the discovery that hydrotalcites become effective catalysts for esters when combined with co-catalysts such as ethylene glycol, fatty acids and standard alkali catalysts (5, 6). These discoveries effectively launched the development... [Pg.299]
