Definitions

  • This invention relates to an improved cigarette paper.
  • the principal objectof this invention is to provide an improved cigarette paper that on burning yields a smoke substantially free of obnoxious components.
  • a further important object is to provide cigarette paper with modified burning characteristics so that the generation of disagreeable gases during combustion is substantially eliminated.
  • cigarette paper which is essentially cellulosic material in fiber form has intimately associated therewith a finely divided, mineral-type, siliceous catalyst which being incombustible and refractory remains substantially unchanged during combustion of the cigarette paper and functions like a catalyst in modifying the combustion of the paper so that the resultant combustion gases and vapors are substantially free of the undesirable components formed when cigarette paper is burned in the absence of the siliceous catalyst.
  • Typical suitable siliceous catalysts are acid-treated clays, heat-treated montrnorillonite, and natural and synthetic silicates containing some hydrogen atoms which are relatively mobile.
  • these siliceous'materials survive the combustion of the cigarette paper as particulate solids while exerting a favorable influence on the burning of the cellulosic content of the cigarette paper, I believe that they act as catalysts in the sense that the usual aldehydic or acidic or hydrocarbon-type products 2,755,207 Patented July 17, 1956 2 of combustion are not at all formed or, if formed, are promptly further oxidized to the harmless form of carbon dioxide and water vapor so that the smoker observes no foreign taste or odor.
  • a class of catalysts with the proper acidic nature which can be used is that of solid particles containing silica and such amounts of ditficultly reducible metal oxides that the molecular ratio of silica to the other oxides exceeds appreciably the value of 1.
  • Another cracking catalyst has been described by OKelly et al. in ind. and Eng. Chem, 39, 154 (1947), as being prepared by the co-precipitation of the hydrous oxides of silicon and aluminum in a weight ratio of 9:1 of silica to alumina.
  • a tri-component cracking catalyst consisting of silica, alumina and zirconia has been described by Thomas et al. in J. Am. Chem. Soc., 66, 1694 (1944).
  • Cracking catalysts can be prepared by using natural clays as a starting material. Many clays contain silica and alumina in a ratio which corresponds to the postulate that the number of moles of silica exceed appreciably the number of moles of alumina or other oxide. However, some of these clays contain, instead of mobile hydrogen atoms combined with excess silica, other atoms, such as alkali and alkaline earth atoms. Such clays can be activated by removing part or all of the alkali and alkaline earth atoms and replacing them with hydrogen atoms by treatment with acid. Other clays, which already in their original composition have a potential acidic nature by having the proper ratio of silica to alumina or other oxides, can be activated by heat treatment (cf. Alexander Grenall l. c.).
  • siliceous catalyst is a combination of a major weight proportion of silica and a minor weight proportion of one or more difficulty reducible metal oxides; this combination may be effected synthetically or it may be derived from natural materials like clays through activation by heat and/or acid treatment.
  • the finely powdered siliceous catalyst can be incorporated in the cigarette paper in various ways and at ditfercnt stages of the manufacture of the paper.
  • the powdered siliceous catalyst used in this invention may be dispersed in the aqueous pulp of cellulosic fibers from which the paper is made or it may be added while the cigarette paper is being formed from the pulp.
  • the catalyst may be applied to the surface of the cigarette paper; calendering or a small amount of adhesive such as methyl cellulose may be used to improve the adhesion of the powdered catalyst deposited on the paper.
  • the siliceous catalyst is brought into close and uniform association with the fibrous cellulosic content of the cigarette paper so that the latter may subsequently be burned without evolving unpleasant combustion products.
  • siliceous catalyst used in cigarette paper in accordance with this invention depends upon the efiicacy or activity of the chosen siliceous catalyst. in general. the addition of the siliceous catalyst falls in the approximate range of 20% to 60% based on the weight of cellulosic material in the cigarette paper. Preferably. siliceous catalysts, like good hydrocarbon cracking catalysts, are usually employed in the proportion of about 45% to 55% based on the weight of cellulosic material.
  • the fibrous ccllulosic pulp for a conventional cigarette paper is uniformly admixed with a finely powdered siliceous catalyst (passing through a ZOO-mesh sieve) which is a silica gel containing about 11% by weight of alumina (ground Sovabead catalyst of Socony-Vacuum Company).
  • a finely powdered siliceous catalyst passing through a ZOO-mesh sieve
  • the quantity of catalyst used corresponds to approximately 50% by weight of the dried cellulosic material in the pulp.
  • the fibrous pulp containing the admixed siliceous catalyst is then formed into cigarette paper in the usual manner.
  • An improved cigarette paper comprising substantially purified cellulosic material and a hydrocarboncracking, activated siliceous catalyst in powdered form in intimate association with said cellulosic material.
  • the activated siliceous catalyst is a synthetic catalyst comprising a major weight proportion of silica and a minor weight proportion of at least one ditficultly reducible metal oxide.
  • An improved cigarette paper comprising a major weight proportion of substantially purified cellulosic material and a minor weight proportion of a hydrocarboncracking, activated siliceous catalyst in powdered form uniformly dispersed in said cellulosic material.
  • the activated siliceous catalyst comprises a major weight proportion of silica gel impregnated with a minor weight proportion of alumina.
