2. tobacco replacement material according to claim 1, characterized in that the salts of the organic Acids are present in amounts of 0.5 to 2% by weight, based on the exchange material.

The German patent application DE-OS 00 491.2-41 describes a tobacco replacement material, which a) contains a matrix of cellulose material as the combustible material and also b) a non-combustible filler, where a) and b) are present in such mixing ratios that one is for the use of the replacement material usable burning rate is given, wherein the Celiulosematerial is a cellulose derivative or its salt with the repeating anhydroglucose unit of the formula

represents, in which at least one of the radicals R is a lower alkyl radical, a lower hydroxyalkyl radical, a <r, is the lower carboxyalkyl radical or a mixture of these radicals and the remaining radicals R are hydrogen atoms and the mean degree of substitution is 0.2 to 3.0, the weight ratio of matrix to Filler is 25:75 to 75:25.

This tobacco substitute material shows substantial improvements over other known ones Tobacco substitutes, however, is still another improvement in terms of taste, smell and smell Amount of components released into the smoke is desirable. This task is accomplished through a tobacco substitute of the type mentioned at the outset, which is characterized in that it also contains up to 5 % By weight, based on the exchange material, of a salt of acetic acid, formic acid, propionic acid, Oxalic acid, malonic acid, lactic acid, malic acid, citric acid or tartaric acid with a metal from the Contains alkali or alkaline earth group.

The salts of the organic acids are in amounts of 0.5 to 2% by weight, based on the exchange material! before.

Suitable cellulose material are, for example, carboxymethyl cellulose, hydroxyethyl cellulose, carboxymethylhydroxyethyl cellulose, Methyl cellulose and carboxymethylated starch do particularly well.

The non-flammable fillers are used as non-toxic finely divided materials with an average Minimum size of the particles from 0.2 μm to 1.0 mm, in particular from 0.2 to 50μπι. The maximal The particle size of the finely divided fillers is preferably 0.25 mm, in particular 0.1 mm. Suitable as Fillers are organic and inorganic compounds as well as the elements, insofar as they are non-toxic, i.e. H. at

oral ingestion of the substance itself or its Combustion products pharmacologically ineffective im Meaning strong adverse effects are.

The best results are obtained with inorganic compounds. Inorganic compounds, the are suitable as fillers, preferably consist of a cation according to column A and an anion according to Column B.

A. iron B. lithium molybdenum Oxides sodium nickel Hydrated oxides potassium Rubidium Hydroxides Cesium Silicon Carbonates magnesium palladium Phosphates Calcium tin Aluminates strontium zinc Stannates barium titanium Zincates manganese zirconium Silicates aluminum copper Carbides cerium cobalt

Particularly preferred inorganic compounds are, for example, alkali and alkaline earth carbonates, oxides, silicates, aluminum silicates, aluminates and aluminum hydroxide. Inorganic compounds in their naturally pre-germinating form, such as Dolomite, perlite, magnesite, diatomaceous earth and vermiculite, are also suitable

As already mentioned, in order to achieve a glucose speed comparable to that of tobacco, this is Matrix to filler weight ratio 25:75 to 75:25. By mixing the ingredients in these Ratios, an exchange material is obtained, the smoldering rate with that of Tobacco is comparable if it is smoked under analogous conditions, i. H. about 3 to 10 mm / minute in the form of a usual cigarette. A glow speed of this order of magnitude corresponds to one Number of puffs of about 12 to 5 for a cigarette is smoked with a cycle of 60 seconds each.

The tobacco exchange material according to the invention is produced by intimately mixing cellulose material, filler, salt and water and forming films from the mixture. The mixture usually contains about 65 to 95% water at the time of forming the film, for example by casting, but it is also possible to work with proportions of water outside this range . The films are then dried, usually by passing them through a heating zone. The conditions for film formation are generally set so that films are obtained which, after drying, have a thickness of about 51 to 510 μm, preferably 127 to 178 μm.

A second mixture was made from the above-mentioned ingredients and additionally with 1% by weight Potassium acetate made.

The mixtures, which contained about 85% water, were cast into films which were then dried became. The dried films, which had a thickness of 127 to 178 μm, became chips of about 1.0 cm long and 0.9 mm wide and cut into cigarettes 85 m long and 8 mm in diameter shaped. Each cigarette contained 1.1 grams of tobacco substitute material.

The cigarettes produced in this way were smoked with a device every 60 seconds each took a puff of 35 ml for 2 seconds. The pressure drop, i.e. H. the flow resistance that occurs when Aspiration of air at an amount of 1050 ml / minute through the column was determined. That Tar weight was determined by sucking the smoke from the cigarette through a Cambridge filter, that removed 98% of the solid particulate matter and was weighed before and after smoking. The amount of Gas phase components was determined by chromatographic analysis. The puff count is the number of Puffs required to smoke the cigarette to a length of 30 mm.

The results obtained are compared to the results obtained with smoking a more common., Exclusive obtained from tobacco existing cigarette of the same weight and size were named in the following table.

In addition to the significantly reduced amounts of substances released in the smoke, there was a noticeable one Improving the taste of the tobacco substitute material, that contained Kaiiumacelai, opposite the achieved untreated replacement material. As the above values show, the modified substitute material burns slower and has a more desirable moist smoke.

Surprisingly, in the case of tobacco, the addition of 1% potassium acetate did not result in a desirable one A change in the chemistry of the smoke or in the taste achieved. The addition of 1% lithium chloride to the tobacco substitute material resulted in no change other than a slight change in the smoke Irritant effect was imparted.

It is not intended to be bound by any particular theory, but it is believed that Addition of the salts of the organic acids to the tobacco substitute material marked improvements can be achieved by two mechanisms. First, excess water is dehydrated by the Salt introduced into the smoke during smoking, creating a more humid smoke with less irritation is formed. Second, there seems to be a fusing effect of the salt and the inorganic Fillers must be present that the. combustion occurs »- and pyrolysis products in iler-! iauptrauchstrorn with special needs.

The tobacco replacement material according to the invention was described above as a combination of matrix, filler and salt of an organic acid are described, but other materials can also be used in small amounts can be added. These include, for example, agents that modify the ash, such as glass fibers and organic fibers, agents for modifying taste and smell such as tobacco extracts, synthetic ones Flavors and aromas or sugar, coloring substances such as charcoal, food coloring and inorganic pigments, plasticizers and humectants such as butylene glycol, glycerin and Propylene glycol, as well as wetting agents in question.

The tobacco substitute material can be reconstituted by itself or in any desired combination with tobacco Tobacco or other tobacco powder be processed into cigarettes and the like.
