[0048] Prepare the gas chromatograph:

[0049] Adopt Agilent 6890N gas chromatograph, chromatographic column adopts HP-5 (30m * 0.32mm * 0.25 μ m), hydrogen flame ionization detector, take benzyl benzoate as internal standard; Gas chromatography conditions are as follows: carrier gas: He, Flow: 2.5ml / min; Inlet temperature: 300°C; Injection volume: 1μl, split ratio 10:1; Detector temperature: 300°C, Hydrogen flow: 30ml / min, Air: 300ml / min, Makeup gas: He, 30ml / min; the heating program is as follows: the initial temperature is 100°C, hold for 0.5min, increase to 180°C at a rate of 30°C / min, and then maintain at a rate of 15°C / min to 300°C for 10min. Preparation of standard working curve:

[0050] 1) Preparation of standard stock solution: Accurately weigh three kinds of phthalate standard products dibutyl phthalate (DNBP), diisobutyl phthalate (DIBP), dimethyl phthalate Esters (DMP) 500mg, dilute with acetone to a 100ml volumetric flask, and make a 5mg / ml mixed standard stock...

Embodiment 2

[0080] Prepare the gas chromatograph:

[0081] Adopt Agilent 6890N gas chromatograph, chromatographic column adopts HP-5 (60m * 0.32mm * 0.25 μ m), hydrogen flame ionization detector, take benzyl benzoate as internal standard; Gas chromatography condition is: carrier gas: He, Flow: 3.0ml / min; Inlet temperature: 270°C; Injection volume: 1μl, split ratio 30:1; Detector temperature: 310°C, Hydrogen flow: 35ml / min, Air: 350ml / min, Makeup gas: He, 25ml / min; heating program: initial temperature 100°C, hold for 0.5min, increase to 180°C at a rate of 30°C / min, then increase to 300°C at a rate of 15°C / min, and maintain for 10min.

[0082] Standard working solution preparation process is the same as embodiment 1, difference is in preparation standard stock solution, weighs dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate ester (DIBP), dibutyl phthalate (DNBP), butyl benzyl phthalate (BBP), bis(2-ethyl)hexyl phthalate (DEHP), phthalic acid Dioctyl ester (DNOP), d...

Abstract

The invention belongs to tobacco field, especially relating to a method for measuring phthalic acid ester (PAE) in water-based adhesive for tobacco. The method comprises the following steps: extracting phthalic acid ester (PAE) in water-based adhesive for tobacco by acetone, measuring by gas chromatography, using HP-5 or an equivalent chromatographic column, using a flame ionization detector (FID) and taking benzyl benzoate as an internal standard substance. The method for measuring phthalic acid ester (PAE) in water-based adhesive for tobacco provided by the invention is accurate in measurement, simple in operation, high in sensitivity and good in repeatability, which is applicable to carrying out qualitative and quantitative measurement on phthalic acid ester (PAE) in water-based adhesive for tobacco for technicists in enterprises of tobacco field and tobacco bonding adhesive and fills up the technical gap in the field.

Description

(1) Technical field [0001] The invention belongs to the field of tobacco, in particular to a method for determining phthalates in water-based adhesives for tobacco. (2) Background technology [0002] Tobacco water-based adhesive is one of the smoking materials, mainly used for the bonding of cigarette laps, cigarette mouthpieces, centerlines of filter rods, cartons and small box packaging. The production process of water-based adhesive for tobacco is affected by the raw material formula, operating process and other conditions. At present, most manufacturers add certain phthalates as plasticizers to improve the performance of the adhesive. Therefore, at present, most Some tobacco water-based adhesives contain more or less phthalates. [0003] Phthalates are a class of environmental hormones, mostly used in polyvinyl chloride plastics to enhance elasticity, also used in cosmetics, and used as plasticizers in the production of adhesives to enhance the overall performance of th...
