Diphenylamine ((N-фенил)-анилин) 2921440000
Diphenylamine is a precursor in the production of antioxidants for polymers.
Diphenylamine ((N-phenyl) -aniline) is colorless crystals that darken in the light, melting point 54-55 ° C, boiling point 302 ° C. Easily soluble in diethyl ether, benzene, acetone, carbon tetrachloride.
Solubility at 25 ° C in 100 g ethanol - 44 g, methanol - 57.5 g, water - 0.03 g. Diphenylamine - original a product in the production of antioxidants for polymers; stabilizer and phlegmatizer for thermal and weather resistance of cellulose nitrates, including pyroxylin powder; an intermediate product in the synthesis of triarylmethane and azo dyes, insecticides; corrosion inhibitor for mild steel.
Used in analytical chemistry to detect ions,, and other oxidants, as a redox indicator (E0 = + 0.75 V).
