2,2,4-trimethyl-1,3-pentanediol monoisobutyrate isomers were analyzed and identified by gas chromatography/mass spectrometry. The method has applied electron impact mass spectrometry (EI-MS)to obtain the characteristic fragment ion data, and determine the physical spectrum of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate isomers by further analysis of the possible fragmentation pathways and characteristic fragment ion of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate isomers, and use structurally similar compounds for confirm-ing, which provide reliable basis for paint coalescent testing.
