Abstract

Interactions between triphenyltin chloride (TPTCl) and several anions in organic solvents were evaluated by using a paper electrophoresis and a conductometric titration. Nitrobenzene solutions containing trioctylmethylammonium chloride (TOMACl),(TOMASCN), nitrate (TOMANO3) and perchlorate (TOMAClO4) were used as impregnating solutions for the paper electrophoresis. The 0.1 M TPTCl nitro-benzene solution was spotted on the filter paper impregnated with the nitrobenzene solution of above quaternary ammonium salts. After electrophoresis, the TPTCl spots on the filter paper was detected by spraying a mercury (I) nitrate solution which leads color development. The TPTCl spot migrated toward the anode during electrophoresis when TOMACl and TOMASCN were used as supporting electrolytes The migration distance of TPTCl spots was proportional to the elapse of electrophoresis time. On the other hand, in the case that TOMANO3 and TOMACIO4 were used as supporting electrolytes, the TPTCl spots did not migrate from the originally spotted point. These results indi-cate that TPTCl behaves as an anion which presumably due to that Cl and SCN ions coordinate to TPTCl to form anionic adducts in nitrobenzene, whereas TPTCl behaves as a neutral species in the TOMANOj and TOMAClO solutions because of nointeraction of TPTCl with NO, and CIO| ions. In the condurtomctric titration, a nitrobenzene solution containing 0.1 MTOMACl, TOMASCN, TOMANO3 or TOMAClO, was ti-trated with a nitrobenzene solution containing 10 M TOTCI. A steep decrease in electric conductivity was observed by adding the TPTCl solution until the amount of TPTCl was equal tothat of TOMACl or TOMASCN in the case of titration of the TOMACl anil TOMASCN solutions. No significant change in conductivity was observed in the titration of the TOMANOj and TOMAClO, solutions. An equivalent relationship between the amount of TPTCl and Cl or SCN ion indicates that the CM or SCN ion coordinates to TPTCl to form a I : I complex. TPTCl- or TPTClSCN-, in nitrobenzene, which supports the findings in the electrophoresis experiments. It can be concluded that no interaction exists between TPTCl and NOj and CIO- from the electrophoresis and the conductometrictitration.
