Unformatted text preview: PERP Program – Maleic Anhydride - New Report Alert April 2005 Nexant’s ChemSystems Process Evaluation/Research Planning (PERP) program has published a new report, Maleic Anhydride (03/04-7). To view the table of contents or order this report, please click on the link below: http://www.nexant.com/products/csreports/index.asp?body=http://www.chemsystems.com/reports/show_cat.cfm?catID=2 Uses Maleic anhydride (MAN) is a versatile molecule that lends itself to many applications requiring multifunctionality. With three active sites (two carboxyl groups and one double bond), it is an excellent joining and cross-linking agent. The broad range of derivatives is shown in Figure 1. Starting at the top of Figure 1 and moving clockwise, a description of major maleic anhydride chemistries and derivatives now follows: • The catalytic hydration of maleic anhydride yields malic acid – an important acidulant in the food and personal care industry. • The catalytic hydrogenation of maleic anhydride yields succinic anhydride which can be hydrolyzed to the acid. Esters of succinic acid are used in the agrichemicals industry. • The reaction of maleic anhydride with phthalic anhydride with propylene glycol yields a commodity unsaturated polyester resin which is usually dissolved in styrene for use in reinforced compounds, artificial marble, etc. • The Diels Alder addition of maleic anhydride with polyisobutylenes yields succinimides which form key components in lubricant additives when reacted with polyamines, etc. • Maleic anhydride copolymers with styrene, ethylene vinyl acetate, etc, serve a number of niche market segments for adhesives, coatings, anti-fouling agents, etc. • Polysuccinimides and polyaspartic acid are newer developments targeted at detergent and anticorrosion applications. • Butanediol and derivatives represent the outlet for unrefined maleic anhydride supporting downstream industries such as engineering polymers, spandex fibers, solvents and specialties. -2- Figure 1 Maleic Anhydride Derivative Tree MalilccAAcdd Ma i ci i TTartaricAcidd artaric Aci SSuccinate uccinate Esterss Ester AsparticcAAcid Asparti cid Succinicc Succini Acidd Aci FumaaricAAcid Fum ric cid Succcincc Suc ini i Anhydridee Anhydrid Maleic AAcid Maleic cid Diisobutyl l Diisobuty Hexahydrophthalicc Hexahydrophthali Annhydride A hydride Compoundss Compound Unsaturatedd Unsaturate Polyyesters Pol esters Tetrahydrophthalicc Tetrahydrophthali Anhydridee Anhydrid Polyyisobutenyl Pol isobutenyl Succinimidess Succinimide Methhyl Met yl tetrahydrophthalicc tetrahydrophthali Anhydridess Anhydride Lubricant t Lubrican Additivess Additive Alpha Olefin Alpha Olefin Succinimidess Succinimide Agrichemicals/ / Agrichemicals SSpecialities pecialities PPolysuccinimides olysuccinimides Styrenee Styren Copolymerss Copolymer EVAA EV Copoolymers Cop lymers Butanediol l Butanedio Polyasparticc Polyasparti Acidd Aci Tetrahydrofurann Tetrahydrofura γγ-Butyrolactone -Butyrolactone PTMEG PTMEG PP:4117/Sec_1 -3- • Maleic anhydride finds extensive use in agrichemical intermediates for pesticides and herbicides. • Maleic anhydride can be reacted with alpha olefins to provide intermediates for a whole host of applications from lubricants through to personal care products. • The reactions with diolefins such as butadiene and isoprene yield specialty anhydrides used for curing agents in epoxy resins serving primarily electrical/electronic markets. • The hydration and isomerization of maleic anhydride yields maleic and fumaric acids which find widespread uses in fine chemicals, resins, acidulants, etc. Extensive discussion is provided in the report for major end uses such as unsaturated polyester resins; fumaric, malic, maleic, and succinic acids; specialty adducts; lubrication oil additives; agricultural chemicals; and styrene and other copolymers. Miscellaneous other end uses are mentioned briefly. Technology There are various process options available for the production of maleic anhydride that must be considered by potential producers for choosing the process configuration optimum for any particular local situation. Process options include: • • • • • • Feedstock (benzene, n-butane) Reactor (fixed-bed, fluid-bed) Energy integration (co-product, power, etc.) Recovery (aqueous, solvent) Purification approach Feed recycle or one-through It is fair to say that in the final analysis the reactor is still the heart of the maleic anhydride process and will continue to focus the mind of chemists and engineers alike in improving conversion, selectivity and throughput. The report generically discusses the influences of the various options on the maleic anhydride process. Specific process descriptions are provided for the processes offered by major licensors Huntsman, Lonza/ABB Lummus, and Scientific Design. -4- Process information also is provided for selected maleic anhydride derivatives: • Unsaturated polyester resins • Polyisobutenyl succinamides • Fumaric acid • Polyaspartic acid • Butanediol Economics Cost of production estimates are provided for the generic process configurations shown in Table 1.

Aqueous recovery processes can provide a larger co-product steam credit than solvent systems. This emphasizes the site-specific needs of maleic anhydride technology with respect to energy integration. Fixed costs form only a modest proportion of production cash costs in the 18 – 25 percent range. So while scale is important, energy integration has a much greater impact on production costs. Production cost estimates are also included for unsaturated polyester resins, fumaric acid, polyaspartic acid, and polyisobutylene succinic anhydride. Commercial Analysis The report presents global maleic anhydride demand by end use and by region for the period 19982015. Maleic anhydride demand by region in 2004 is shown in Figure 2, while Figure 3 presents the details of the North American (U.S. and Canada) maleic anhydride market by end use in 2004. The global supply/demand balance is also estimated for the same period. Corollary information is provided for North America, Western Europe, and Japan. -5- Unsaturated polyester resins are by far the largest segment of global maleic anhydride demand, and they are expected to remain so throughout the forecast period. Developed economies are showing demand growth in line with average GDP. However, demand growth could prove stronger given that the functionality of the maleic anhydride molecule is constantly leading to new products. If new businesses based on polysuccinimides and polyaspartic acid can be developed rapidly, then there may be even stronger demand for maleic anhydride in developed economies. End-use markets like polyester resins, succinimides, copolymers, agrichemicals, malic and fumaric acids are developing strongly in Asia, especially China, encouraging new investment.
