Embodiment 3

[0107] The 8 kinds of butyl ester components of the target detection object in the present invention are insoluble or slightly soluble in water, and most of them are miscible with various organic solvents such as alcohols, ethers and hydrocarbons. Therefore, after screening, we selected the following four solvents to investigate their solubility in water-based glue for cigarette packaging: A—N,N-dimethylformamide, B—ethanol, C—isopropanol, D—n-hexyl alkyl.

[0108] Weigh four 0.1g (accurate to 0.1mg) samples of water-based adhesive for cigarette packaging of the same type, add 1mL of the above-mentioned four solvents A, B, C, and D respectively, and observe the degree of dissolution of the water-based adhesive. For specific results, see figure 1 . like figure 1 As shown, the experimental results show that the water-based glue for cigarette packaging can be quickly and completely dissolved in solvent A with a little manual shaking; in solvents B and C, it is only slightly sol...

Abstract

The invention provides a method for analyzing butyl ester components in water-based glue for cigarette packaging. The samples to be tested and the standard samples containing butyl ester components are respectively measured by headspace-gas chromatography mass spectrometry, and the retention time is compared for qualitative analysis. , using the internal standard standard curve method to quantify, determine the content of butyl esters in the sample to be tested, wherein the sample to be tested is a mixture of glue sample, N,N-dimethylformamide and internal standard solution, the The standard sample is a mixture of standard solution and internal standard solution. The present invention provides a method for analyzing butyl ester components in water-based glue for cigarette packaging. The sample pretreatment method is simple and fast, with good separation, accurate and reliable detection results, high sensitivity and good repeatability, which can fully meet the requirements of cigarette packaging water. It is required for the analysis of butyl ester components in gum base.

Description

technical field [0001] The invention belongs to the technical field of tobacco chemical component analysis, and relates to a method for analyzing butyl ester components in water-based glue for cigarette packaging. Background technique [0002] Volatile organic compounds in water-based adhesives for cigarette packaging mainly come from residual monomers and organic solvents. There are many kinds of butyl esters, such as butyl acetate, butyl propionate, butyl butyrate and the corresponding isomers. Usually, butyl esters are volatile to a certain extent, and have obvious odors (mainly fruit aromas), which are irritating to eyes and noses. Cigarette packaging water-based adhesives may contain butyl esters, which may affect consumers' sensory experience if they migrate into cigarettes. [0003] At present, there are related reports on the determination of volatile components in water-based adhesives for cigarette packaging, such as ethyl acetate, methyl acetate, vinyl acetate m...
