Laser desorption/ionization fourier transform mass spectrometry and fast atom bombardment spectra of nonvolatile polymer additives

Laser desorption Fourier transform mass spectra (LD-FTMS) of a variety of nonvolatile polymer additives are compared with fast atom bombardment spectra (FAB) of the same materials. Both a pulsed carbon dioxide laser and a neodymium-YAG laser with outputs of 10.6 and 1.064 mum, respectively, were used to obtain LD-FTMS spectra of all samples. Three sterically hindered phenols and other additives containing a variety of functionalities including thioester, phosphite, phosphonite, and hindered amine groups were examined. In general, FAB spectra show undesirably large amounts of fragmentation, while molecular ion species dominate LD-FTMS spectra. It is concluded that LD-FTMS spectra are superior to FAB spectra for analysis of these common polymer additives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Tetrakis(2,4-di-tert-butylphenyl) [1,1′-biphenyl]-4,4′-diylbis(phosphonite), you can also check out more blogs about38613-77-3
