Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Optical Thin Film Standardization Technical Committee (SAC/TC431) centralized. This standard was drafted. China Lucky Group Co., Ltd., Baoding Exit Inspection and Quarantine. The main drafters of this standard.

Optical functional film triacetate cellulose (TAC) film Determination of plasticizer content

1 Scope

This standard specifies the triacetate cellulose (TAC) film plasticizer (dibutyl phthalate DBP, butyl benzyl phthalate That is, BBP, dioctyl phthalate DEHP, di-n-octyl phthalate or DNOP, diisononyl phthalate DINP, adjacent Diisodecyl phthalate, ie DIDP, dimethoxyethyl phthalate, ie DMEP, 2-biphenyldiphenylphosphate, ie BDP and phosphoric acid Triphenyl ester (TPP) content by gas chromatography - mass spectrometry method. This standard applies to triacetate cellulose (TAC) film plasticizer (DBP, BBP, DEHP, DNOP, DINP, DIDP, DMEP, BDP and TPP) content of the test.

2 principle

TAC membrane was dissolved with dichloromethane, n-hexane was added to precipitate the polymer therein, and after filtration, the plasticizer was left in the filtrate, and the gas phase color Spectrum - mass spectrometry detection, external standard method.

3 Reagents and materials

3.1 dichloromethane. pure chromatography. 3.2 n-Hexane. Chromatography pure. 3.3 Standards. DBP, BBP, DEHP, DNOP, DINP, DIDP, DMEP, BDP, TPP standards. purity not less than 99.5%. 3.4 acetone. pure chromatography. 3.5 test gas. helium, purity ≥ 99.999%.

4 instruments and equipment

4.1 gas chromatography - mass spectrometer. 4.2 oscillator. 4.3 analytical balance (accuracy of 0.1mg).

5 analysis steps

5.1 Vessel preparation Glassware used in the experiment, after acetone rinse, ventilated to dry reserve. 5.2 Preparation of standard stock solution Weigh accurately the right amount of standard (3.3), respectively, with methylene chloride (3.1) dissolved and transferred to 50mL volumetric flask, constant volume, shake, too
