Fine chemical companies are generally either small and privately held or divisions of larger companies, such as Eastman Fine Chemicals (United States) and Lonza (Switzerland). Examples of large public fife science companies, which market fine chemicals as a subsidiary activity to their production for captive use, are Hoffmann-La Roche, Sandoz, and Boehringer Ingelheim, which produce and market bulk vitamins and liquid crystal intermediates, dyestuff intermediates, and bulk active ingredients, respectively. Table 3 fists some representative companies having an important fine chemical business.

Shaped products used for adsorbent purposes are generally less sophisticated and therefore less expensive than catalytic products. In 1985, it was reported that 10,000 t/yr of activated alumina adsorbents were produced in the United States. North American producers of Bayer process-based activated aluminas include Alcoa, La Roche (formerly Kaiser Chemicals), Discovery, and Alcan. Gel-based activated aluminas are produced by La Roche, Vista, and several of the major catalyst manufacturers. In Europe, principal sources of supply are Rhc ne-Poulenc and Condea.
