Definitions
- the present invention relates, on the one hand, to a method for producing an acidified filter for tobacco products by impregnating a fibrous or flat filter material according to the preamble of the main claim, and also to the use of such filters for .
- esters of organic edible acids such as citric acid, tartaric acid, succinic acid, malic acid and sugar acid have been used, which can be finely dispersed in glycerol triacetate on the fibers of the filter material.
- the disadvantage of this process is that the esters of the respective polycarboxylic acids have only very weak retention compared to basic smoke constituents, since in this case the reactive acid groups are esterified and the selective retention of basic smoke components is therefore no longer available.
- the acid anhydrides of the corresponding di- or polycarboxylic acids are dissolved in the carboxylic acid esters used as filter hardeners and hydrolyzed after spraying onto the filter fibers.
- Disadvantages of this process are, on the one hand, the very complex and therefore expensive preparation of the acid anhydrides and, on the other hand, the instability of the dissolved anhydrides, which are already hydrolyzed to the corresponding acids by traces of water in the solvent used or by atmospheric moisture and crystallize out of the solvent as acids.
- the di- or polycarboxylic acids are applied in the form of very fine particles either according to EP 09 13 100 A2 via a metering device directly to the strand of filter material during filter production or these very fine particles are in an organic according to DE 39 04 239 Cl , liquid medium suspended and the suspension obtained applied to the filter material.
- the production of the small particles by micronization is extremely expensive; on the other hand, either additional metering devices are required on the filter manufacturing machine or the suspensions used show instability, as a result of which the fine particles settle on the floor over time.
- no process is known in which solid organic acids or their acidic salts can be applied to the filter material in an economical manner in a standard process for filter production in the filter hardeners normally used.
- the object of the invention is to propose a process for the production of an acidified filter for tobacco products, in which the food acids or their acid salts which are crystalline at ambient and processing temperatures can be dissolved together with an organic solvent used as a filter hardener, such as a carboxylic acid ester hardener , so that the clear solution obtained can be applied to the filter material in a conventional manner.
- a filter hardener such as a carboxylic acid ester hardener
- a method for producing an acidified filter for tobacco products by impregnating a fibrous or flat filter material with a) physiologically and sensorially acceptable mono-, di-, or polycarboxylic acids or hydroxy acids with up to 8 carbon atoms and 2 to 3 carboxyl groups or with their acidic salts and b) a carboxylic acid ester hardener component, which is characterized in that these pleasure acids or their acidic salts and the carboxylic acid ester hardener component are added an alcoholic solution vendor from the group of methyl, ethyl, propyl, iso-propyl, buryl and iso-butyl alcohol or mixtures thereof or in solution and the solution thus obtained is applied to the filter material.
- the distribution of the edible acids or their acidic salts on the filter fibers is very fine and homogeneous, so that extremely high effectiveness can be achieved.
- the application of the edible acids or their acid salts does not require any special measures in the manufacture of the filters. No machine modifications are necessary, and the critical stability and homogeneity of the solution used does not limit the processability in any way.
- the process allows the use of inexpensive raw materials, since standard products can be used for the production of the required solution without special, expensive pretreatment such as micronizing or dissolving at temperatures above 100 ° C.
- esters here called carboxylic acid ester hardeners, as described in DE 39 04 239 Cl can be used as filter hardening agents, whereby glycerol triacetate (triacetin), polyethylene glycol acetate or propionate and especially triethylene glycol diacetate (TEGDA) are particularly suitable ,
- the solution of edible acids or of their acid salts, the carboxylic acid ester hardener component and the alcoholic solubilizer is preferably used for a filter material which consists of fibers or nonwovens made of cellulose acetate, cellulose, polyethylene or polypropylene.
- Maleic acid, succinic acid, glutaric acid, tartaric acid, malic acid, citric acid and / or acetylcitric acid or their acid salts are preferably used as edible acids, the acidic alkali and especially potassium salts or ammonium salts being used in particular as acid salts.
- Further edible acids which can be used according to the invention are from the group of the hydroxy acids also glycolic acid, lactic acid and sugar acids. 3-hydroxymandelic acid, salicylic acid, 2-hydroxycinnamic acid (coumarin) and ascorbic acid, or from the group of dicarboxylic acids also oxalic acid, malonic acid, adipic acid acid, pimelic acid, suberic acid and phthalic acid as well as from the group of monocarboxylic acids also cinnamic acid, phenylacetic acid and benzoic acid.
- the alcohols used as solubilizers according to the invention have good dissolving power for the polycarboxylic acids or for their salts.
- Ethanol is particularly preferred since it is particularly well suited as a solubilizer and even small amounts are sufficient to e.g. in glycerol triacetate (triacetin) and ultimately because ethanol is also a solvent that is otherwise common in the tobacco industry.
- solubility for cellulose acetate fibers i.e. the corresponding cellulose acetate filters harden faster.
- the procedure is preferably such that, based on the total solution, the proportion of the edible acids or the acid salts in a concentration of 1 to 20% by weight and the alcoholic solubilizers in an amount of 0.1 to 10% in particular from 4 to 8% by weight. It is also expedient if the concentration of the edible acids or that of the acid salts thereof in the solution of the carboxylic ester hardener component and the alcoholic solubilizer is adjusted such that when the solution is applied, it is 0.1 to 5 based on the fiber weight % By weight and in particular 0.5 to 2% by weight.
- the acidified filter or the acidified filter material obtained according to the invention can be used as a filter plug or as part of the same for a cigarette paper tube, but also in rod form as a filter for smoking devices such as pipes or cigarette tips. It is particularly advantageous to use the filter material obtained according to the invention as a filter plug or as part of the same for a cigarette, cigar or cigarillo, the proportion of the edible acids or that of the acid salts in the filter material being 0.1 to 10 mg per cigarette or cigarillo is.
- Example 1 The invention is explained below using exemplary embodiments: Example 1:
- a filter rod with the dimensions of 126 now length, corresponding to 6 times the length of a filter, and with a diameter of 7.83 was now used.
- This acetate filter corresponded to a specification of 2.5y / 35,000 HK and had a draw resistance of 405 mm WS.
- the acetate weight was set at 638 mg, i.e. 3.19 mg malic acid had to be sprayed on, or 0.53 mg / cigarette. 57 mg of triacetin were used as the hardener component.
- To prepare the triacetin malic acid solution 5.6 kg malic acid and 100 kg triacetin were vigorously stirred for about 15 minutes in an approx. 200 liter stainless steel container. This results in a partial solution and fine dispersion of malic acid. 4 kg of ethanol were then added to the complete solution, the malic acid being completely dissolved after 20 minutes of further stirring.
- the amount sprayed onto the filter was given with 60.2 mg solution / filter rod.
- the alcohol was not taken into account because it evaporates during or immediately after production.
- the physical parameters such as tensile resistance and hardness were not affected by malic acid.
- a filter rod of the format 100 mm in length, that is 4 times the length of a normal filter plug, and 7.85 mm in diameter was used with an acetate of the specification 2, ly / 33,000 SK and a Draw resistance of 415 mm WS used.
- the acetate weight in this case was 531 mg, i.e. 13.275 mg malic acid or 3.3 mg malic acid / cigarette were sprayed on. 45 mg triacetin per filter rod was used as hardener component.
- the plasticizer-malic acid solution was prepared as in Example 1 but with amounts of 29.5 kg of malic acid and 100 kg of triacetin.
- the amount of ethanol added after about 15 minutes was 8 kg in this case and the mixture was and faster solution heated to 35 ° C.
- the finished solution was stable.
- the amount applied here was 58.3 mg solution / filter rod.
