Embodiment 1

[0043] (1) Preparation of internal standard solution: take the internal standard phenylethyl propionate, use ethanol as the extractant, and prepare a 1mg / mL ethanol phenylethyl propionate solution;

[0044] (2) Standard solution preparation

[0045] Take by weighing 0.0250g methanol, sec-butanol, sesamol and musk xylene respectively, dissolve and settle to 250mL with absolute ethanol, and prepare the mixed mother liquor of methanol, sec-butanol, sesamol and musk xylene of 100 μg / mL, Accurately pipette 0.01mL, 0.02mL, 0.05mL, 0.1mL, 0.2mL, 0.5mL, 1mL of mixed mother liquor of methanol, sec-butanol, sesamol and musk xylene into a 10mL volumetric flask, and add 50μL of phenylethyl propionate ethanol solution (the concentration of phenylethyl propionate is 1mg / mL), and then dilute to volume with ethanol to prepare mixed standard working solutions of different concentrations of methanol, sec-butanol, sesamol and xylene musk, standard sequence: 0.1μg / mL, 0.2μg / mL, 0.5μg / mL, 1μg / mL...

Embodiment 2

[0055] Accurately weigh 1g of tobacco feed liquid sample (accurate to 0.0001g), accurately add 10mL of absolute ethanol, and 50μL of ethanol solution of phenylethyl propionate (the concentration of phenylethyl propionate is 1mg / mL), and then add 3g Anhydrous sodium sulfate (baked in a muffle furnace at 520°C for 5 hours before use), shake gently for a few times, then shake on a shaker at a rate of 190rpm for 35min, let stand, filter with a 0.45μm organic phase filter membrane, and the filtrate is subjected to GC / MS analysis; Assay method is as described in Example 1, and the chromatogram is shown in Figure 4 The measured methanol content in the sample is 34.8mg / kg, the content of sec-butanol is 54.8mg / kg, and the content of xylene musk is 21.6mg / kg.

Embodiment 3

[0057] Accurately weigh 1g of tobacco feed liquid sample (accurate to 0.0001g), accurately add 10mL of absolute ethanol, and 50μL of ethanol solution of phenylethyl propionate (the concentration of phenylethyl propionate is 1mg / mL), and then add 2g Anhydrous sodium sulfate (baked in a muffle furnace at 500°C for 4.5h before use), shake gently for a few times, then shake on a shaker at a rate of 180rpm for 30min, let stand, filter with a 0.45μm organic phase filter membrane, and carry out the filtrate GC / MS analysis; Determination method is as described in embodiment 1, and chromatogram sees Figure 5 , The content of sesamol in the sample was measured to be 69.1mg / kg.

Abstract

The invention discloses a method for measuring contents of methanol, sec-butyl alcohol, sesamol and musk xylene in an additive for cigarettes. The method comprises the following steps of: preparing an internal standard solution, preparing a standard solution, preparing a sample solution, and performing quantitative and qualitative analysis on the methanol, sec-butyl alcohol, sesamol and musk xylene by employing gas chromatograph-mass spectrometer (GC / MS). By utilizing the GC / MS, the contents of methanol, sec-butyl alcohol, sesamol and musk xylene in the additive for the cigarettes can be directly measured, and the method has the advantages of easiness and convenience in operation, high rapidness, high accuracy, high sensitivity and high repeatability.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing of tobacco additives, and mainly relates to a method for measuring the content of methanol, sec-butanol, sesamol and xylene musk in the tobacco additives. Background technique [0002] In the process of cigarette product design and production and processing, in order to improve product quality and meet processing needs, companies often need to choose additives such as sweeteners, preservatives, humectants, combustion enhancers, and plasticizers. The use of these additives is one of the important factors affecting the quality and safety of cigarette products. [0003] Industrial alcohol (methanol) is the simplest saturated monohydric alcohol, also known as "wood alcohol" or "wood essence", which is a colorless and volatile liquid with an alcohol smell. Toxic, can directly violate human body cells and tissues. Especially damage the optic nerve retina, drinking 5-10mL by mista...
