Vi. Kelarev et al., Influence of sterically hindered phenol derivatives of Delta(2)-imidazoline and thiazolidin-4-one on thermooxidative stability of synthetic oils, PETR CHEM, 40(1), 2000, pp. 46-50
A series of 3-substituted 2-(4-hydroxy-3,5-di-tert-butylphenyl)thiazolidin-
4-ones were prepared by condensation of azomethines derived from 4-hydroxy-
3,5-di-tert-butylbenzaldehyde with thioglycolic acid and their structure wa
s confirmed by IR and H-1 NMR spectroscopy. The synthesized compounds, as w
ell as Delta(2)-imidazolines containing the sterically hindered phenol moie
ty, were shown to have promise as effective additives enhancing thermooxida
tive stability of synthetic oils.
