The complexation of titanium (IV) with azocompound synthesized on the basis of para-tret-butylphenylazo-4ꞌ-nitrobenzene (HR) was studied using spectrophotometric method. There has been found optimal conditions of the formation of complex and its extraction by butenol-1. Molar coefficient of absorption equals to 4.2·104. By Komar method the resistance constant of the complex βk=(9.04±0.01)·108 and equilibrium constant of the complexation reaction (3.4·104) were calculated. Berꞌs low is followed at the concentration of titanium 1.0–10mkg/sm3. Butanol-1 was used as an extrac-tant. Methods extraction-atomic-absorption determination of titanium in alloys has been developed
