Autor: Anthony P. Bimbo, D. E. Walters, Eric L. Miller, Stuart M. Barlow, Snorri Thorisson

Publikováno v: Journal of the American Oil Chemists' Society. 74:1085-1088

Nine laboratories participated in a collaborative test to determine the iodine value (IV) of eight samples of fish oil (four with IV 150) with either carbon tetrachloride (AOCS Official Method Cd 1–25) or cyclohexane/acetic acid (AOCS Recommended P

8-Methylethoxyquin: A possible replacement for ethoxyquin

Autor: Frank D. Gunstone, Snorri Thorisson, Roy Hardy

Publikováno v: Journal of the American Oil Chemists’ Society. 70:931-933

When acting as an antioxidant, ethoxyquin is converted mainly to a 1,8′-dimer and to a quinone-imine, with the latter itself acting as a powerful antioxidant. The 8-methyl derivative of ethoxyquin was prepared in the expectation that this would not

EPR study of radical intermediates from the oxidation of 6-ethoxy-2,2,4-trimethyl- and 6-ethoxy-2,2,4,8-tetramethyl-1,2-dihydroquinoline

Autor: Snorri Thorisson, Richard A. Jackson, Raphael C. Mordi, John C. Walton, Frank D. Gunstone

Publikováno v: University of St Andrews CRIS

The EPR spectra of 1,2-dihydro-6-ethoxy-2,2,4-trimethyl- and 1,2-dihydro-6-ethoxy-2,2,4,8-tetramethyl-quinolin-1-yl radicals were observed in heptane solution. The hyperfine splittings showed that this class of radical is extensively delocalised with
