Fluorine chemists take their expertise to the sunshine state

December 31, 2002

The American Chemical Society, the world's largest scientific society, will convene its 16th biennial winter fluorine conference, Jan. 12-17, 2003, in St. Pete Beach, Fla., hosted by the ACS' Division of Fluorine Chemistry. Over 100 scientific presentations will be made at the winter conference and approximately 250 scientists and students will attend the meeting at the Tradewinds Island Grand Hotel (727-367-6461).

Fluorine chemistry is a unique and specialized branch of chemistry with important commercial applications in areas such as pharmaceuticals, agrochemicals, plastics and polymers, and refrigerants. Members of the division promote their interest in fluorine and its positive impact on society by organizing technical conferences and sponsoring research scholarships. The division's membership is international, with representation from all of the industrialized nations.

In addition to in-depth scientific presentations, the division will present the Society's Award for Creative Work in Fluorine Chemistry on Jan. 16 to David A. Dixon of the Pacific Northwest National Laboratory in Richland, Wash. Dixon, a Battelle Fellow, has expanded the understanding of fluorine chemistry and advanced the use of computational chemistry including chlorofluorocarbon (CFC) replacements, organofluorine molecules and inorganic fluorides.

Other conference highlights include the following symposia and sessions:

Monday, Jan. 13
11:10 a.m.

  • Green chemistry and solvents(Novel methods for the preparation of fluorine-containing ionic liquids) -- Ionic liquids containing fluorine can absorb a wide variety of chemical compounds. They are environmentally friendly compounds because of their decreased vapor pressure in ordinary conditions. The researcher will explain new methods for the synthesis of a variety of organic ionic liquids. (Darryl D. DesMarteau, Clemson University, Department of Chemistry, H. L. Hunter Laboratory, Clemson, S.C., 864-656-4705, fluorine@clemson.edu)

    Tuesday, Jan. 14
    8 a.m. -5p.m.

  • New technology developments(Design of transparent fluoropolymer photoresists for semiconductor manufacture at 157 nanometers) -- The latest information on the development of new materials for the next generation of smaller and faster computer chips will be presented. (Andrew E. Feiring, DuPont, Central Research & Development, Wilmington, Del., 302-695-1841, andrew.e.feiring@usa.dupont.com)

  • Computer chip advances(Computational approaches to the design of 157 nanometer photoresists) -- In the design of faster computers, new chemicals are being used to make new computer chips with refined features. The presenter will highlight these new computational approaches for faster computers. (David A. Dixon, Pacific Northwest National Laboratory, W. R. Wiley Environmental Molecular Sciences Laboratory, Richland, Wash., 509-372-4999, david.dixon@pnl.gov).

  • Measurements of non-hydrogen based acids(Quantitative scale for Lewis acidity) -- Commonly used by chemical manufacturers in every aspect of consumers lives, including gasoline refinery, technology development and industrial manufacturing, Lewis acids are now calculated on scales comparable to the pH and pK scales used to describe acidity in swimming pools, skin cleansers and shampoos. The researcher will explain this quantitative scale. (Karl Christe, Edwards Air Force Base and the University of Southern California, Air Force Research Laboratory, Edwards, Calif., 661-275-5194, karl.christe@edwards.af.mil) Thursday, Jan. 16
    8 -12 noon

  • Agricultural industry compounds(Pentafluorosulfanylbenzenes containing active halogens) -- Potentially useful research findings for the development of new agrochemicals will be discussed. (Joseph S. Thrasher, fluorine@bama.ua.edu, The University of Alabama, Department of Chemistry, 205-348-8436 or 205-348-8434).

    The winter fluorine conference chair is William B. Farnham, DuPont Central Research & Development, Wilmington, Del. He can be reached at 302-695-2459 or william.b.farnham@usa.dupont.com. Richard M. Flynn, 3M Company, St. Paul, Minn. is Chair of the Fluorine Division. He can be reached at 651-736-1473 or rmflynn@mmm.com.
