Description

Anodic dissolution of niobium in anhydrous methanol in the presence of sodium methylate was studied. Sodium hexamethoxyniobate, NaNb(OMe)6, has been synthesized by electrochemical method for the first time. A method for recovery of niobium methylate from sodium hexamethoxyniobate was developed. It is shown that pure niobium methoxide, Nb(OMe)5, can be isolated as a result of reaction between NaNb(OMe)6 formed and ammonium chloride. Water soluble hydroxo complex NaNb(OH)6 forms upon hydrolysis of NaNb(OMe)6

Abstract (Russian)

Изучен процесс анодного растворения ниобия в безводном метаноле на фоне метилата натрия. Впервые электрохимическим способом синтезирован гексаметоксиниобат натрия NaNb(OMe)6. Найден способ выделения метилата ниобия из гексаметоксиниобата натрия. Показано, что в результате реакции образовавшегося NaNb(OMe)6 с хлористым аммонием может быть выделен чистый метоксид ниобия Nb(OMe)5. При гидролизе NaNb(OMe)6 образуется растворимый в воде гидроксокомплекс NaNb(OH)6
