Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 1802-2006 "indoor paints glycol ethers by gas chromatography", and SN/T 1802-2006
Compared to, in addition to editorial changes, the major technical changes are as follows.
--- The Chinese title "glycol ether" to "glycol ethers and esters", the English title "ethyleneglycolmonoalkyl
ethers "to" ethyleneglycolmonoalkylethersandesters ";
--- "1" and part of the adjustment, delete the words "EGBE" increased "ethylene glycol monomethyl ether acetate, ethylene glycol ethyl ether
Acetate and diethylene glycol butyl ether acetate ";
--- The "Principle 2" in the "use of ethanol and petroleum ether" to "solvent."
This standard by the National Certification and Accreditation Administration Committee.
This standard was drafted. Chinese Academy of Inspection and Quarantine.
The main drafters of this standard. Chen Wei, Cai Tianpei, Falls Apart, Yu Wen Lin, Wang Zheng.
This standard replaces the standards previously issued as follows.
--- SN/T 1802-2006.
Determination of indoor paints glycol ethers and esters
Gas chromatography
1 Scope
This standard specifies the interior paint glycol monomethyl ether, ethylene glycol ethyl ether, ethylene glycol monomethyl ether acetate, ethylene glycol acetate and diethyl ether
Gas chromatographic method glycol butyl ether acetate content.
This standard applies to indoor paints glycol monomethyl ether, ethylene glycol ethyl ether, ethylene glycol monomethyl ether acetate, ethylene glycol acetate and diethyl ether
Determination of glycol ether acetate content.
2 Method summary
Glycol ether esters and paint, solvent ultrasonic extraction, volume, centrifuged, filtered and analyzed by gas chromatography - flame ionization
Detector method (GC-FID) detection, external standard, gas chromatography - mass spectrometry (GC-MS) confirmed.
3 Reagents and materials
Unless otherwise indicated, the reagents used were of analytical grade.
3.1 Methanol. chromatographically pure.
3.2 ethyl acetate. chromatography.
3.3 anhydrous sodium. Burning 4h at 650 ℃, store in a sealed desiccator.
3.4 standard (purity mass fraction). Ethylene glycol monomethyl ether ≥98%, glycol ether ≥98%, ethylene glycol monomethyl ether acetate ≥98%,
≥98% ethylene glycol ether acetate and diethylene glycol butyl ether acetate ≥98%.
3.5 mixed standard stock solution. Weigh glycol monomethyl ether, ethylene glycol ethyl ether, ethylene glycol monomethyl ether acetate, ethylene glycol and diethylene ether acetate
Alcohol ether acetate (3.4) each 1.0g (accurate to 1mg) in 100mL flask, dissolved in methanol (3.1) and set the volume, vibration shake, that
The solubility was above five each 10000mg/L of mixed standard stock solution.
3.6 working standard solution. Pipette 5.00mL were mixed standard stock solution (3.5) in 50mL flask with a solvent [aqueous coating
Methanol (3.1) as the solvent, the solvent coating using ethyl acetate (3.2) as the solvent] diluted to the mark, shake well. That was
1000mg/L of the working standard solution, obtained by serial dilution of 500mg/L, 100mg/L, 20mg/L, 5mg/L, 1mg/L of
Working standard solutions.
4 Equipment
4.1 Balance. a sense of the amount of 0.1mg.
4.2 Gas chromatograph. with flame ionization detector (FID).
4.3 Gas chromatography - mass spectrometry. equipped with electron impact ionization (EI).
4.4 ultrasonic cleaning.
4.5 high-speed centrifuge. 12000r/min.
4.6 syringe filter sample with an organic membrane filters, membrane pore size of 0.45μm.
