Embodiment 1

[0023] 1) Add 5 grams of heme and 250ml of 85% formic acid aqueous solution into a 500ml round bottom flask, slowly and gradually add 1.5 grams of iron powder under reflux, continue to reflux for 20 minutes after the addition, cool and filter to remove the iron powder, and pour the mother liquor into In 1L of aqueous solution containing 20% ​​ammonium acetate, place it overnight, filter and collect the solid, and dry to obtain the filter tip additive.

[0024] ESI-MS (positive mode): 563 [M+1].

[0025] 2) The prepared filter additive is suspended in ethanol at 0.3% of the weight of the carrier, and evenly sprayed onto the tea foam of the carrier.

[0026] 3) When the tow is formed, the carrier with the filter tip additive is added to the tow filter rod at a rate of 6 mg / piece to make a cigarette. Borgwaldt RM200A smoking machine was used for smoke detection according to the standard smoke detection method, and the test results are shown in Table 1.

Embodiment 2

[0027] Example 2: The difference from Example 1 is that in 2) the prepared filter tip additive is suspended in water at 0.3% of the weight of the carrier, and evenly sprayed on the carrier tea foam. The smoke test results are shown in Table 1.

Embodiment 3

[0028] Example 3: The difference from Example 1 is that in 2) the prepared filter additive is suspended in ethanol at 0.6% of the weight of the carrier, and evenly sprayed onto the carrier tea foam. The smoke test results are shown in Table 1.

Abstract

The invention relates to a preparation method of filter nozzle additive for lowing ammonia in the smoke of cigarette and application thereof. The method comprises the following steps: dissolving hemachrome into formic acid water solution, adding iron powder, and then carrying out refluxing, cooling and filtering in sequence; then preparing protoporphyrin compound additive through decompressing and concentrating filter liquor; or, adding ammonium acetate water solution with a certain degree into filter liquor so as to separate out solid, and then filtering and drying to obtain protoporphyrin compound additive. Filter nozzle additive with the carrier weight of 0.05 to 10 percent is floated into the solution, and evenly sprayed onto a carrier and the carrier attached with additive is added into a filter candle of a cigarette during tow forming so as to prepare a composite filter nozzle. Compared with the prior art, the method provided by the invention has the advantages as follows: raw material used for preparing the filter nozzle additive is hemachrome which is cheap and easy to access, the entire preparing cost is low, the operation and the after treatment are simple and convenient, and industrial production can be realized easily. Particularly, harmful components such as ammonia can be remarkably lowered.

Description

technical field [0001] The invention belongs to the field of cigarette manufacturing, and in particular relates to the preparation of a cigarette filter tip additive with harm reduction and its application in cigarette harm reduction. Background technique [0002] With the improvement of people's health awareness, higher requirements are put forward for the safety of cigarettes. Improving the safety of cigarettes and reducing the release of harmful components in cigarette smoke is the development direction of international cigarette technology, and it is also an inevitable demand for the development of Chinese-style cigarettes. [0003] In 1990, D. Hoffmann and S. S. Hecht published a list of 43 harmful components in smoke in 12 categories. Then, the analysis and reduction of the special harmful components of cigarette smoke gradually became the focus of tobacco scientific research (D.Hoffmann, I.Hoffmann, K.EI-Bayoumy, Chem.Res.Toxicol., 2001, 14 (7), 767-790 ).
