Embodiment Construction

[0034] In order to further understand the present invention, the preferred embodiments of the present invention are described below in conjunction with the examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0035] The method for detecting glycerol triacetate in cigarette filter sticks provided by the present invention is the same as the principle of gas chromatography provided by YC / T331-2010, but the solvent, internal standard and chromatographic column used in it have been replaced and optimized through research. the reaction conditions.

[0036] 1, the solvent of the present invention adopts Virahol.

[0037] (1) Chromatography experiment: Isopropanol and ethanol peaks on HP-5 chromatographic column respectively, chromatographic conditions: YC 144-2008, injection port: 250°C, injection volume: 1 μL, split ratio: 30:1 , ...

Abstract

The invention discloses a method for detecting glyceroltriacetate in cigarette filter rods, which uses gas chromatography and uses isopropanol as a solvent. In the method provided by the invention, the isopropanol serving as the solvent can achieve the same gasification effect as ethanol, and is small in toxin and insusceptible to deliquescence and causing hydrolysis of glyceroltriacetate. In theinvention, methyl laurate or propylene carbonate which is used as an internal standard substance is insusceptible to decomposition in light and can be stored easily, a chromatographic column which isa weak/medium-polarity chromatographic column, weak-polarity chromatographic column or medium-polarity chromatographic column has less impurity peaks and small baseline drift. When the method provided by the invention is used for detecting the glyceroltriacetate in the cigarette filter rods, large-batch detection can be realized and the detection result is accurate.

Description

technical field [0001] The invention relates to a detection technology for cigarette filter sticks, in particular to a method for detecting triacetin in cigarette filter sticks. Background technique [0002] Glycerol triacetate for tobacco is the esterification product of glycerin and glacial acetic acid under catalytic conditions. It is used in tobacco, cosmetics, casting, medicine, dyes and other industries, and is non-toxic and non-irritating. Used as a plasticizer for cigarette filter rods in the tobacco industry, the main component of which is glycerol triacetate to bond and solidify acetate tow, so that cigarette filter rods have good elasticity, air permeability and appropriate hardness , directly and indirectly affect the filter rod molding, cigarette rolling, and even the internal and external quality of finished cigarettes. Quantitative detection of components in triacetin for tobacco is very important. [0003] At present, the domestic tobacco industry measures ...
