Description

  

  Procédé pour diminuer la teneur de la fumée du tabac en éléments     toxiques     en     .particulier    celles des     cigarettes       La présente invention a pour objet un procédé des  tiné à diminuer la teneur en goudrons et autres subs  tances     nocives    dans la fumée du tabac, en particulier  dans celle des cigarettes.  



  Ce     procédé    consiste à mélanger au tabac une subs  tance     adsorbante,    par exemple des     granules    de charbon       actif.    Dans ce cas on constate une     activation    de la com  bustion et le résultat de cette adjonction consiste en une  visible augmentation de la capacité de     rétention    d'un       élément-filtre,    par exemple en acétate de cellulose,

       fixé     à l'extrémité     buccale    de la     cigarette    en éléments     retirés     à la phase     particulaire    de la     fumée.        L'activation    de la       combustion    détermine une notable     diminution    du taux  d'oxyde de carbone dans la phase     gazeuze    de la     fumée.     Les divers charbons utilisés ont     permis    d'observer un  maximum d'effet lors de la mise en     oeuvre    d'un charbon  actif à haute porosité et activé selon la méthode étudiée  par René  <RTI

  L'utilisation de dérivés de la silice comme     adsorbants     a permis de constater un effet analogue surtout lorsque  la substance     siliceuse    a été obtenue à partir de charbon  poreux imprégné de tétrachlorure de silicium soumis  ensuite à     l'action    de l'eau ou d'alcools     aliphatiques    ou  aromatiques.



  Method for reducing the content of tobacco smoke in toxic elements, in particular those of cigarettes The present invention relates to a process for reducing the content of tars and other harmful substances in tobacco smoke, in particular in that of cigarettes. cigarettes.



  This process consists of mixing an adsorbent substance with tobacco, for example granules of activated carbon. In this case an activation of the combustion is observed and the result of this addition consists of a visible increase in the retention capacity of a filter element, for example in cellulose acetate,

       attached to the mouth end of the cigarette in parts removed in the particulate phase of the smoke. The activation of combustion determines a notable reduction in the carbon monoxide level in the gas phase of the smoke. The various carbons used made it possible to observe a maximum effect during the implementation of an activated carbon with high porosity and activated according to the method studied by René <RTI

   ID = "0001.0025"> Seiler.



  The use of silica derivatives as adsorbents has made it possible to observe a similar effect, especially when the siliceous substance has been obtained from porous carbon impregnated with silicon tetrachloride then subjected to the action of water or aliphatic alcohols. or aromatic.
