✦ Synopsis

Field desorption mass spectra have been recorded of n-dotriacontane, n-tetracosanoic acid and hexadecyl hexadecanoate as representatives of long straight-chain alcohols, acids and esters respectively. Molecular or quasimolecular ions were formed almost exclusively with fragmentation at a low level.

Mixtures of long chain compounds have also been examined and the components characterized as their molecular ions. These included a fraction of higher ~-~o diols from hydrolysed carnauba wax, unhydrolysed carnauba wax and a previously uninvestigated wax from a Livistonia sp.

Results have shown that field desorption mass spectrometry has a most promising role in wax investigation by the ready characterization of constituents up to molecular weights of 2000 and greater.
