Only two compounds (Nonox CI. Tinuvin P) showed low-temperature luminescence characteristics from their phosphorescence. Irganox 1010 exhibited an apparent low-temperature fluorescence of different spectra characteristics to the weak room-temperature emission, but which did not show detectable phosphorescence. The low-temperature luminescence observed for Irganox 1010 may, however, be short life-time phosphorescence which was undetectable with the rotating can phosphoroscope. Four compounds (Topanol OC, Ionox 330, Irganox 1076 and Irganox 1093) showed 54 Chemical Analysis of Additives in Plastics relatively weak room-temperature emission in ether-isopentane-ethanol mixture but no low-temperature fluorescence or phosphorescence was detectable.

In an attempt to overcome the difficulty of interference effects by other polymer additives in the ultraviolet spectroscopic determination of phenolic antioxidants Wexler 7 makes use of the bathochromic shift exhibited by phenols on changing from a neutral or acidic medium to an alkaline one. This shift is due to the change of absorbing species because of solute-solvent interaction.

Analysis of Sample. Grind a representative sample in the Apex Mill. Weigh about 1 g of the sample into a 100 ml round-bottomed flask and add 20 ml cyclohexane. Fit a condenser to the flask and allow the cyclohexane to reflux on a water bath for 1 hr. Wash down the condenser with 20 ml cyclohexane, remove the flask from the bath, cool to room temperature and shake well. Filter through a No. 802 filter paper into a 100-ml separating funnel. Wash the filter paper with a further 10 ml cyclohexane. Add 25 ml freshly prepared sodium hydroxide solution, shake for 3 min then allow to settle.
