Problems solved by technology

[0004] But there are some problems in this method: the chromatographic peaks of glyceryl monoacetate and glyceryl diacetate in the sample cannot be separated; due to the different response factors of various components in the sample on the hydrogen flame ionization detector, the peak The area percentage example is not the same as the actual content percentage example, and there is an error in estimating its actual content ratio from the peak area percentage example of triacetin by the peak area normalization method; and are equal, but the ratio is different, the actual content of other components is different, which will c...

Embodiment

[0038] Take some samples to be tested for qualitative detection by mass spectrometry. The samples to be tested contain oil triacetate, oil monoacetate, glycerol diacetate and other small amounts of additives. In this experiment, oil triacetate, monoacetate Oily acetic anhydride and glyceryl diacetate were quantitatively detected.

[0039] 1) Prepare standard solution:

[0040] Reagents used in the experiments:

[0041] Trans-anethole Beijing Bailingwei Chemical Technology Co., Ltd.;

Abstract

The invention provides a method for quantitatively detecting glycerol triacetate for tobacco. One substance or two substances in trans-anethole and propylene carbonate is/are used as internal standardsubstances to prepare extraction, and quantitative analysis is carried out on the extraction by an internal standard method. In the preparation process, the detected components and the internal standard substances are mixed together to be injected into a chromatographic column, and the changes of injection volume can not influence quantitative results. The mass percentage content of the detectedcomponents in the samples of the glycerol triacetate for tobacco can be detected more accurately, and monoacetin and glycerol diacetate can be distinguished.

Description

technical field [0001] The invention relates to a method for testing components in tobacco, in particular to a method for quantitatively detecting components in triacetin for tobacco. Background technique [0002] Tobacco triacetin 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. In the tobacco industry, it is used as a plasticizer for forming cigarette filter rods. The main component, glycerol triacetate, can bond and solidify acetate tows, making 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. The tobacco industry standard YC 144-2008 of the People's Republic of China stipulates that triacetin for tobacco with a triacetin content ≥ 99...
