Abstract: Several decomposition products in the mass spectra of 4-n-alkyl esters of trimellitic anhydride stem from processes involving abstraction of an alkyl hydrogen by an oxygen atom in the anhydride group. Such hydrogen migration to the formally distant functional group occurs also in 4-n-alkyl trimellitimidates and 1, Zdimethyl 4-nalkyl trimellitates, though not in methyl n-alkyl iso-or terephthalates. The mass spectra of triglycerides of longchain ...
