isopropyl acrylate, acrylic acid n-propyl ester, 2-propenoic acid, 1,1-dimethylethyl ester,
acrylic acid benzyl ester, 2-octyl acrylate, sec-butyl acrylate, ethyl methacrylate,
isobutyl methacrylate, butyl methacrylate, 2-methyl-2-acrylic acid-1,1-dimethylethyl
ester, phenyl methacrylate, 2-methyl-2-propyl acrylate, benzyl methacrylate, sec-butyl
methacrylate and isopropyl methacrylate.
Part 2 – Liquid chromatography applies to the determination of migration of 6 kinds of
acrylic acid, methacrylic acid and their esters in food contact materials and products,
including acrylic acid, methacrylic acid, 2-hydroxyethyl acrylate, 2-hydroxyethyl-2-
methyl-2-acrylate, methyl acrylate and methyl methacrylate.
Part 1 – Gas chromatography-mass spectrometry
