Fast atom bombardment mass spectra of iodonium salts

Autor: Kenneth L. Busch, Helen H. Schurz

Publikováno v: Organic Mass Spectrometry. 27:604-608

Positive-ion fast atom bombardment mass spectra and linked-scan tandem mass spectra were measured for aromatic iodonium salts. The mass spectra usually contain the intact cation of the iodonium salt as the base peak, fragment ions of lower abundance

Fast atom bombardment ionization of porphyrins: studies of reduction processes and use in coupling of thin-layer chromatography with mass spectrometry

Autor: Helen H. Schurz, Kenneth L. Busch

Publikováno v: Energy & Fuels. 4:730-736

The positive-ion fast atom bombardment mass spectra of porphyrins usually contain substantial signals corresponding to ions from the reduced forms of the protonated molecule, specifically those ions that incorporate extra hydrogen atoms. Occurrence o

During the early 1980’s importation of rapeseed oil into Spain for human consumption was illegal, except for the Canary Islands, although denatured rapeseed oil could be legally imported for industrial use. Denaturation of imported food oils with c

A shocking and previously unknown epidemic of food-related illness gained recognition in May of 1981. The toxic oil syndrome (TOS), as it was to become known, was caused by the consumption of an oil that was purported to be edible olive oil, but was

Products of aniline and triglycerides in oil samples associated with the toxic oil syndrome

Autor: I A Borda, Robert H. Hill, Larry L. Needham, Helen H. Schurz, Rossanne M. Philen, M. Posada de la Paz, S. L. Bailey

Publikováno v: Chemical research in toxicology. 9(6)

The toxic oil syndrome (TOS) was a devastating disease that occurred in Spain in 1981. The disease was associated with the consumption of aniline-denatured and refined rapeseed oil that had been illegally sold as olive oil. Many aniline-derived oil c
