Definitions

  • the invention relates to a smoking product, in particular tobacco with or without wrapping material, containing nicotine N'-oxide.
  • the invention is based on the knowledge that the cis isomer of nicotine N'-oxide leads to a considerable deterioration in the taste of smoke. Accordingly, the invention is primarily directed to a smoke product whose smoke has an increased nicotine content due to the addition of nicotine N'-oxide, the above-mentioned taste impairment of the smoke by the cis isomer being able to be avoided.
  • smoking product used here includes cut tobacco, pipe tobacco, cigarettes, cigarillos or cigars To understand tobacco with or without added non-tobacco materials and / or reconstituted tobacco.
  • the smoking product of the invention can be produced with or without wrapping material, wherein the wrapping material used can be cigarette paper, cigar or cigarillo wrappers made of tobacco or non-tobacco materials.
  • the smoking product of the invention contains trans-nicotine-N'-oxide which is free or essentially free of cis-nicotine-N'-oxide or has a content of at most 10% by weight of the cis isomer, namely in an amount up to 5% by weight, based on the dry weight of the smoke product.
  • the trans-nicotine N'-oxide to be used according to the invention which is free or essentially free of cis-nicotine N'-oxide or has a content of at most 10% by weight of the cis isomer, can be used in tobacco or non-tobacco materials contained therein and / or the wrapping materials which may be present, for example be added to the cigarette paper or the cigar or cigarillo wrappings made of tobacco and / or non-tobacco materials.
  • the addition is advantageously carried out on the finished tobacco material, e.g. in the form of an aqueous solution, or on the finished wrapping material, e.g. in an alcoholic or aqueous-alcoholic solution.
  • the invention is further directed to a process for the production of trans-nicotine N'-oxide that is free or substantially free of cis-nicotine-N'-oxide is particularly directed for use as an additive to smoking products of the invention.
  • the invention is therefore further directed to a process for the production of trans-nicotine N'-oxide, which is free or essentially free of cis-nicotine N'-oxide, requires short reaction times, and in which only auxiliaries which are unobjectionable under food law come into use.
  • the process of the invention is characterized in that the oxidation is carried out in the presence of catalytic amounts of non-oxidizing inorganic and / or organic acids with a pK value of less than 5.
  • the reaction temperature during the reaction should in any case be as low as possible higher reaction temperatures favor the formation of decomposition products and the cis isomer, albeit only to a small extent.
  • the reaction temperature should never be above 90 ° C, otherwise explosive decomposition of the hydrogen peroxide can occur.
  • Monocarboxylic, dicarboxylic or polycarboxylic acids and their hydroxy, keto or unsaturated derivatives are particularly suitable as catalytically active acids with a pK value of less than 5.
  • the reaction of nicotine with hydrogen peroxide is preferably carried out in essentially equimolar amounts, hydrogen peroxide being initially introduced and nicotine being added dropwise; the reverse procedure is also possible.
  • an oxidizing agent it is expedient to add commercially available hydrogen peroxide in the form of a 30-50% aqueous solution.
  • the acids used as catalysts are preferably used in an amount of 10-150, in particular 20-100 mmol per mole of nicotine.
  • the oxidation mixture obtained during the oxidation is dewatered.
  • the dewatering can preferably be carried out by azeotropic distillation using n-propanol as the azeotropic dewatering agent. Remaining traces of water can be removed from the reaction mixture dried in this way using a molecular sieve (pore size 4A).
  • the trans-nicotine N'-oxide crystallizes out of the dry oxidation mixture in pure form. It can be added to the tobacco and / or the wrapping material in the manner described above, but with up to for cost reasons Can stretch 10 wt .-% of the cis isomer.
  • the cis isomer remaining after working up the oxidation mixture is advantageously reduced to nicotine; the nicotine thus obtained can be oxidized again.
  • the colorless solution thus obtained which is free of nicotine and hydrogen peroxide, can be processed directly.
  • Example 1 The solution obtained in Example 1 is dewatered with n-propanol by azeotropic distillation. The dewatered solution is then dried with molecular sieve (4A). On cooling, pure trans-nicotine N'-oxide crystallizes out of the mixture thus obtained and can be filtered off with suction. The remaining mother liquor contains predominantly cis-nicotine-N'-oxide.
  • the mixture obtained has a cis / trans ratio of the nicotine N'-oxides of 1: 1.67.
  • the crude product thus obtained is mixed with 25 kg of n-propanol and distilled.
  • the reaction residue thus dewatered is then dried with 5 kg of molecular sieve (4A) in 5 kg of methylene chloride.
  • the reaction mixture is subjected to azeotropic dewatering.
  • azeotropic dewatering For this purpose, 10.6 kg of n-propanol are added and a water-containing distillate (75% by mass n-propanol / 25% water) is separated off under a slight vacuum.
  • the low-water residue has a residual water content of 7.7% by mass.
  • Nicotinization of a cigarette strand Nicotinization of a cigarette strand.
  • the tobacco nicotine content is increased with the help of a 10% alcoholic trans-nicotine N'-oxide solution by 1.13% to 2.62%; the addition is made by spraying on the tobacco material.
  • the cigarettes made from the tobacco material obtained in this way have a smoke nicotine yield which is 0.3 mg higher when smoking under DIN conditions.
  • the condensate content remains unchanged compared to untreated cigarettes.
  • Cigarette strand nicotinization Cigarette strand nicotinization.
  • a tobacco mixture with a nicotine content of 1.66% is raised to 6.1% with a 20% aqueous trans-nicotine N'-oxide solution in the leaf cut nicotine content.
  • the cigarettes then made from this tobacco material result in a smoke nicotine yield increased by 0.5 mg when smoking under DIN conditions.
  • the condensate content did not change compared to untreated cigarettes.
  • Ci arettenpapierbahn be reverse with the aid of rollers with a 10% trans-nicotine-N'-oxide solution in water / ethanol (1: 1) moistened and dried in a hot air stream. After drying, the cigarette paper obtained is similar in color and mechanical stability to the untreated pattern and contributes to an increase in nicotine smoke.
  • the amount of the trans-nicotine N'-oxide applied in accordance with the process is 5%, based on the weight of the cigarette paper.
  • Nicotine compensation by adding trans-nicotine N'-oxide before an expansion process is a factor
  • a filler grade with a nicotine content of 1.8% by weight and a moisture content of 11% by weight are made using a trans-nicotine-N'-oxide solution consisting of 4.3 l of water and 200 g of trans-nicotine N'-oxide, brought to an expansion moisture of approx. 18% by weight.
  • trans-nicotine-N'-oxide compensates for the 25% loss of nicotine which is always to be expected in tobacco expansion processes, so that the expanded tobacco with its original nicotine content can contribute to the mixture build-up.
