영문 초록

Acetylsalicylic acid gives a water-insoluble violet complex with alpha-Picolin-Cu(II) reagent. The Complex is extractable well with a mixture of alpha-Picolin-tetrachloromethane solution. the Complex salt dissolved in the mixed solution shows a maximum absorption at 620mmc. It has a melting point at 171oC-173oC and molar ratio of Acetylsalicylic acid: Cu(II): alpha-Picolin was estimated as 2:1:2 by continuous variation method and chelate titration method.
