The second most important use of ketene is in the production of diketene [674-82-8] (3) by controUed dimeri2ation. Diketene has wide utility in the manufacture of pharmaceutical and agricultural chemicals, dyes, pigments and fine chemicals. 

Whereas the eadiest fluorescent-dye pigments would last only 20 days outdoors in a screen-ink film, fade resistance has been improved to such an extent that some modem daylight-fluorescent coated panels stiU have useful color after nine months or mote in Florida sunlight in a 45° exposure tack facing south. The fluorescent layer is usually coated with an acrylic film containing a uv absorber. Indoor-accelerated exposure equipment is, of course, invaluable in the development of such systems. Better dyes and resins very likely will make possible fat mote stable coatings in the future. 

Naphthalenedicarboxylic Acid. NaphthaUc acid readily dehydrates on heating to 1,8-naphthalenedicarboxyhc acid anhydride [81-84-5] (naphthahc anhydride) (41). The anhydride and its imide naphthaUmide [81-83-4] (R = H) (42) are intermediates for important dyes, pigments, optical bleaches, and biologically active compounds. 

Halogenated and 4,5-halogenated derivatives of 1,8-naphthalenedicarboxyHc acid anhydride are useful intermediates for dyes, pigments, and fluorescent whiteners for polymers. 

For example,%aminophenol, dyes, pigments, chemical intermedi-ates, and solvents. Projected for 1993. 

Various appHcations such as lubricant additives, dyes, pigments, and catalysts are under investigation. Tungsten can be deposited from tungsten hexacarbonyl, but carbide formation and gas-phase nucleation present serious problems (1,2). As a result, tungsten halides are the preferred starting material.

Anthropogenic arene snlfonates are structural elements of many industrially important dyes, pigments, and anionic snrfactants, although they are very seldom encountered as naturally occurring metabolites.
