Description

4-Methyldiphenylamine is a polymerization inhibitor that can be used in the manufacture of polymers and paints. It has been shown to inhibit the polymerization of phenylenediamines, biphenyls, anilines, and other compounds. 4-Methyldiphenylamine is not soluble in water and must be dissolved in an organic solvent such as acetone or alcohol before use. This compound is also known for its ability to form complexes with aluminium ions and phosphotungstic acid. It reacts with chloride to form a yellow/brown solid that can be removed by filtration or decantation. The optimal reaction time ranges from 3 hours to 24 hours, depending on the substrate being used. Impurities may include chromatographic peaks at Rf 0.67, 0.59, and 0.50; these impurities can be removed by washing with deionized water or by using a different solvent system during chromatography. 4
