*Millions of pounds per year. Commercial production is based on carbonylation of methyl acetate and on ketene technology utilizing acetic acid. Most acetic anhydride is used captively in the production of cellulose acetate for filter tow and fiber. Eastman capacity includes 1,200 million pounds of material based on synthesis gas from coal, and 600 million pounds based on the ketene process.

In 2000, Celanese quit acetic anhydride production in Celaya, Mexico, eliminating 90 million pounds of capacity.

Profile last published 2/2/98; this revision 2/12/01.

DEMAND
1998: 1,884 million pounds; 1999: 1,902 million pounds; 2003: 1,964 million pounds, projected. Demand equals production plus imports (1998: 28 million pounds; 1999: 30 million pounds) less exports (1998: 165 million pounds; 1999: 172 million pounds).

GROWTH
Historical (1994 - 1999): 1.2 percent per year; future: 0.8 percent per year through 2003.

PRICE
Historical (1994 - 1999): High, $0.495 per pound, tanks, dlvd. East; low, $0.475, same basis. Current: $0.495, same basis.

USES
Cellulose acetates, including cellulose acetate, cellulose diacetate, cellulose triacetate, cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) 86 percent; miscellaneous, including coatings, pesticides, aspirin and acetaminophen, 14 percent.

STRENGTH
Exports of acetic anhydride are strong and will continue to do well, having grown in recent years at 4.2 percent annually. Last year, exported material amounted to 185 million pounds.

WEAKNESS
About 42 percent of acetic anhydride is consumed in cellulose acetate flake used to produce filter tow. Tow, however, is used in cigarette filters, and U.S. demand for cigarettes peaked in 1996, declining at an average annual rate of 8 percent per year since then. Exported filter tow is doing well, offsetting the domestic situation somewhat. Another major outlet for acetic anhydride, acetate derived textile fibers, has experienced a long term decline because of competition from other fibers, particularly polyester.

OUTLOOK
Acetic anhydride is a mature product with over 85 percent of production going into cellulose acetate flake, which in turn, serves well-established markets in filament yarn, cigarette filter tow and cellulose ester plastics. Uses for acetic anhydride other than for cellulose acetates are fragmented and none of them show significant growth potential. Moreover, no major new growth prospects have been identified. Consequently, future growth will be very modest, estimated at 0.8 percent per annum.
