Abstract
5-Hydroxy-7-methoxy-2,2-dimethyl-6-octyl(and 8-octyl)-4-chromanones (2a and 2b) were synthesized via 5,7 dihydroxy-2,2-dimethyl-6-octyl (and 8-octyl)-4-chromanones (1a and 1b) from phloroglucinol as a starting material. Cyclohexane solutions of 1a, 1b, 2a, and 2b were irradiated. The photostability of 2a and 2b was found to be better than that of 1a and 1b. Poly(vinyl chloride) film containing 6, 7 wt.-% of 2b was found to be most stable against photooxidation.
