    The influence of storage conditions and packaging on acetic acid generation in cellulose acetate fibers

    TATUM C.E.; WILSON S.A.; CASPER R.G.; PEARCE M.J.
    Eastman Chemical Company, Kingsport, TN, U.S.A.
    The cellulose acetate polymer used in cigarette filters is made by acetylating wood pulp with acetic anhydride. One advantage of this modified natural polymer is that it readily degrades by multiple mechanisms. While the ultimate products are carbon ...

    The challenges associated with emission ceilings based on multivariate quantile

    VERRON T.(2); BRY X.(1); CAHOURS X.(2); COLARD S.(2)
    (1) UM2, University Montpellier 2, France; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In 2012, we evaluated and presented at the CORESTA Congress [1] the probable impact of emission ceilings as proposed by the joint working group of the WHO Study group on Tobacco Product Regulation (TobReg) [2] using experimental data and we demonstrated ...

    Comparison of the cerulean e-cigarette pressure drop testing instrument to the ces 508 cigarette pressure drop and ventilation tester unit for electronic cigarettes, conventional tobacco burning cigarettes, and filter tips

    AVANTS K.W.(1); WILSON S.A.(2); CLARK J.(1)
    (1) Liggett Group, LLC, Mebane, NC USA; (2) Eastman Chemical Company, Kingsport, TN USA
    The pressure drop or “resistance to draw” of cigarettes and cigarette-like products is a prominent experience for consumers. This poster is a comparison of two commercial instruments with different approaches to measuring pressure drop. The instruments ...

    Potential use of Heavy Metal Atpase (HMA) mutants to reduce cadmium translocation from root to leaf in tobacco

    JULIO E.(1); HERMAND V.(2); COTUCHEAU J.(1); DECORPS C.(1); SENTENAC C.(1); GOSTI F.(2); BERTHOMIEU P.(2); DORLHAC DE BORNE F.(1)

    Heavy metals are naturally present in soils, or can be brought by agricultural practices or spread out by human activities. Some of them are essential for plant development. Cadmium is a non-essential heavy metal which is classified in Group 1 (= known ...

    Photodegradability testing of cellulose acetate filters – outdoor weathering vs. accelerated weathering

    STEACH J.K.; FISHER JONES D.
    Eastman Chemical Company, Kingsport, TN, USA
    Degradation testing in the laboratory is based on understanding a material’s exposure to specific environmental forces, which can play a key role in the mechanisms of degradation. Cellulose acetate filters can be degraded by various environmental forces, ...

    THEME-SEER: Multidimensional exploratory technique to explore the generation process of smoke compounds

    BRY X.(1); VERRON T.(2); CAHOURS X.(2); TEILLET B.(2)
    (1) I3M, UM2, Montpellier, France; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In 2011, we presented at the 2011 CORESTA SSPT Meeting (Graz) [1] a new approach to path modelling based on system extended multiple covariance criteria. We showed why THEME-SEER may be preferred to current methods using either criteria based on ...

    Using a structural model based on a class of generalized covariance criteria, to explore the generation process of smoke compounds

    BRY X.(1); REDONT P.(1); VERRON T.(2); CAHOURS X.(2)
    (1) I3M, UM2, Montpellier, France; (2) SEITA Imperial Tobacco Group, Fleury-les-Aubrais, France
    Our aim is to explore a structural model: several variable groups describing the same units are assumed to be structured around latent dimensions that are linked together through a linear model that may have several equations. This type of model is ...
