Problems solved by technology

[0005] Although many documents and patents currently add some additives and even catalysts to cigarette shreds, except for the traditional potassium and sodium salts, few documents provide the exact data on how additives can reduce the burning temperature of cigarettes
In addition, the selection range of additives is relatively limited. Most of the additives except potassium salt and sodium salt are oxides, which are insoluble in water and conventional solvents. The addition process is cumbersome, and usually requires the use of dispersants and other reagents to mix with them. Can be added after making slurry

preparation example Construction

[0025] The preparation steps of the test cigarette: Dissolve a certain amount of mixed salt in water to make a salt solution of a certain concentration, use the CIJECTOR flavor injection machine to evenly spray 50 μl of the salt solution into the shredded tobacco of the cigarette, and then put the cigarette at a temperature of 22°C Balance in a balance box with ±1°C and relative humidity of 60%±2% for more than 48 hours, and set aside. Take the same cigarette sample, inject 50 μl of water with CIJECTOR flavor injection machine, and use it as a control cigarette, and also balance it in a balance box with a temperature of 22°C ± 1°C and a relative humidity of 60% ± 2% for 48 hours.

[0026] Cigarette smoking is in accordance with "GB 19609-2004 Determination of total particulate matter and tar by smoking machine for routine analysis of cigarettes".

[0027] Cigarette combustion temperature test method: use a thermocouple temperature measuring device, including 8 thermocouples an...

Embodiment 1

[0029] Dissolve 1.34 grams of lithium acetate and 1.34 grams of copper acetate in 5.0 grams of water (the weight ratio of alkali metal:transition metal salt is 50%:50%), stir until completely dissolved to obtain a salt solution; then use CIJECTOR flavor injection machine Evenly inject 50 μl of salt solution into the shredded tobacco of each cigarette, so that the total weight of the mixed salt accounts for 5% of the total weight of shredded tobacco of each cigarette. Put the cigarettes into a balance box with a temperature of 22±1°C and a relative humidity of 60±2% for 48 hours to prepare test cigarette a. The effect of additives on reducing the burning temperature of cigarettes: see Table 1.

Embodiment 2

[0031] Dissolve 1.34 grams of potassium acetate and 1.34 grams of zinc acetate in 5.0 grams of water (the weight ratio of alkali metal:transition metal salt is 50%:50%), stir until completely dissolved to obtain a salt solution; then use CIJECTOR flavor injection machine Evenly inject 50 μl of salt solution into the shredded tobacco of each cigarette, so that the total weight of the mixed salt accounts for 5% of the total weight of shredded tobacco of each cigarette. Put the cigarettes into a balance box with a temperature of 22±1°C and a relative humidity of 60±2% for 48 hours to prepare test cigarette b. The effect of additives on reducing the burning temperature of cigarettes: see Table 1.

Abstract

The invention discloses an additive for reducing burning temperature of a cigarette and application thereof. Mixture of an alkali metal salt and a transition metal salt is adopted as the additive, and an anion of the alkali metal salt is an acetate ion, an oxalate ion or a citrate ion. The additive can be used for reducing the burning temperature of the cigarette. Compared with the contrast cigarette with no additive, the highest burning temperature of the cigarette can be reduced to 51 DEG C by adding a certain quantity of additives into tobacco. The additive has the advantages that the burning temperature of the cigarette can be reduced significantly, and the adding process is simple.

Description

technical field [0001] The invention relates to the field of additives for shredded tobacco of cigarettes, in particular to an additive for reducing the combustion temperature of cigarettes and its application. Background technique [0002] Cigarette combustion temperature is one of the characteristic parameters that affect the chemical components and their release in mainstream and sidestream smoke of cigarettes, and then affect the quality of cigarettes. The cigarette burning temperature directly affects the pyrolysis synthesis reaction of tobacco components and the release of various volatile and semi-volatile components in the smoke during the cigarette burning process. For example, the existence of various condensed aromatic hydrocarbons in mainstream smoke is considered to be mainly produced by high-temperature synthesis, and CO 2 It can be reduced to CO by C, and reducing the combustion temperature can reduce the release of CO. Therefore, it is possible to adjust th...
