ABSTRACT:
A bis(1,1,3,3-tetramethylbutyl)phosphinic acid compound represented by the formula (1) and an extracting agent using the same for separating Co from an aged electroless Ni plating solution. A di(1,1,3,3-tetramethylbutyl)phosphine is produced by carrying out a reaction between phosphine and trimethylpentene in the presence of an organic solvent and a catalyst, then said phosphine is reacted with an oxidizing agent or sulfur to obtain the compound (1): ##STR1## (wherein X.sup.1 and X.sup.2 are O or S).
