Publication number: 20110132381Abstract: A method of forming a filter for a smoking article which includes exposing cellulose acetate fibers to an electron beam process, wherein electron beam process deacetylates the cellulose acetate fibers to render the cellulose acetate fibers water-permeable; and forming a cellulose acetate rod from a tow of the cellulose acetate fibers. Filter plugs of the cellulose acetate fibers are water-permeable and allow discarded filtered smoking articles to rapidly degrade and expose the components to the environment.Type: ApplicationFiled: January 28, 2011Publication date: June 9, 2011Applicant: Philip Morris USA Inc.Inventors: Harvey J. Grubbs, Susan A. Freelin

Patent number: 5497792Abstract: A process is provided for the improved removal of nicotine from tobacco. An essentially nicotine-free solvent in the supercritical or liquid state is fed into a first end of an extraction flow system containing tobacco and a nicotine-rich solvent is discharged from a second end of the extraction flow system. Periodically a portion of extracted tobacco is discharged from the first end of the extraction system while simultaneously a portion of an unextracted tobacco is charged to the second end of the extraction system. Nicotine is then entrapped in an entrapment material or otherwise removed from the solvent and solvent is recycled through the extraction flow system. Various materials are provided as entrapment materials. Among the entrapment materials provided are aqueous solutions containing absorbent selected from various acids and salts.Type: GrantFiled: November 19, 1987Date of Patent: March 12, 1996Assignee: Philip Morris IncorporatedInventors: Ravi Prasad, Harvey J. Grubbs

Patent number: 5018540Abstract: A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco without materially affecting the content of the other components of the tobacco. Tobacco is traversed with a solvent at high pressure and in a physical state which is either a liquid at a pressure of from about 500-300 atmospheres or a supercritical fluid wherein nicotine and the other components dissolve in the solvent. As the single means of removing substances from the solvent, the solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine. The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine.Type: GrantFiled: November 19, 1987Date of Patent: May 28, 1991Assignee: Philip Morris IncorporatedInventors: Harvey J. Grubbs, Ravi Prasad, Tony M. Howell

Unitary pack of smoking tobacco products containing polymeric alcohol flavorant-release compositions
Patent number: 4212310Abstract: A unitary pack of smoking tobacco products is provided in which a flavorant is incorporated in some of the smoking tobacco products in the form of a polymeric alcohol flavorant-release composition which has the general formula: ##STR1## wherein R is selected from aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; R.sup.1 and R.sup.2 are selected from hydrogen and aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; and n is an integer.
