METHOD OF MAKING QUINOXALINE DIE-N-OXIDE AQUEOUS SOLUTIONS STABLE TO LIGHT

摘要

Quinoxaline di-N-oxides used in animal feeds, such as olaquindox, are stabilized against light degradation by substances which absorb light within the wavelength range from 200 to 450 nm, such as quinolines, isoxanthenones, azo dyestuffs, polyenes and/or flavones.
