Problems solved by technology

When the amount is less than 6%, the hardness of the filter stick cannot meet the production requirements, and when it is greater than 10%, it will not have a significant impact on the hardness of the filter stick, but it will cause triacetin to transfer to the inside of the cigarette, thereby affecting the smoking quality of the cigarette
At the same time, other substances mixed into glycerol triacetate may also have an adverse effect on the taste of cigarettes

Embodiment 1

[0020] 1. Instruments and reagents:

[0021] Acetone, chromatographically pure; triacetin sample 1 from a manufacturer.

[0022] 50 mL Erlenmeyer flask; Agilent 6890N gas chromatograph with split / splitless inlet and hydrogen flame ionization detector.

[0023] 2. Sample processing and determination:

[0024] (1) Pipette 0.1 mL triacetin sample into a 50 mL Erlenmeyer flask;

[0025] (2) Add 10 mL of acetone;

[0026] (3) Oscillate on the oscillator for 10 minutes, and take a sample to be tested on the machine;

[0027] (4) Gas chromatography conditions and quantitative methods are the same as YC 144-2008. The content result of measuring this sample is 99.73%. In order to verify the accuracy of the result, the original preparation method was used for sample preparation, GC-FID detection, and area normalization method for quantification, and the content result was 99.72%. See Table 1 for specific data. It is feasible to illustrate that the content determination method of...

Embodiment 2

[0029] For the content determination of triacetin sample 2 from a certain manufacturer, see Example 1 for the experimental procedure.

Abstract

The invention provides a method for measuring the content of glyceryl triacetate. The method is characterized by including the following steps: (1) putting 0.1 mL of glyceryl triacetate sample in a 50 mL of conical flask; (2) adding 10 mL of acetone; (3) oscillating on an oscillator for 10 minutes, and sampling for waiting for testing on a machine; (4) measuring the sample to be measured by a gas chromatographic method, wherein the gas chromatographic condition and the quantitative method are the same as those of YC144-2008. On the condition that the dilution ratio of an original method is almost unchanged, the measuring method provided by the invention is used for optimizing the sample extracting volume, a vessel, a dilution solvent, solvent dosage and the like of the original method. Compared with the prior art, the measuring method has the advantages of simplifying the operation, improving the efficiency, saving the cost and ensuring better stability.

Description

[0001] technical field [0002] The invention relates to the technical field of physical and chemical testing of triacetin content in smoking materials, in particular to a method for measuring triacetin content. Background technique [0003] Glyceryl triacetate is a commonly used plasticizer for cellulose acetate filter rods. In order to achieve sufficient hardness, the target dosage of glycerol triacetate is generally 6% to 10% of the weight of the entire filter rod. When the amount is less than 6%, the hardness of the filter stick cannot meet the production requirements, and when it is more than 10%, it will not have a significant impact on the hardness of the filter stick, but it will cause triacetin to transfer to the inside of the cigarette, thereby affecting the smoking quality of the cigarette . At the same time, other substances mixed in glycerol triacetate may also have an adverse effect on the taste of cigarettes. The higher the purity of glycerol triacetate is, ...
