Abstract
The titrations of metal chlorides and alkali metal alkoxides have been carried out in anhydrous non-aqueous solvent using visual indicators. Basic indicators such as thymolphthalein, thymol blue,m-cresol purple and phenolphthalein have been found to be suitable in detection of double alkoxides. By contrast, the acidic indicators,e.g., bromo-cresol purple, bromo-cresol green, bromo-phenol blue and bromo-thymol blue were able to detect simple alkoxides only.
The formation of a number of alkoxy complexes of the type M [M′ (OR)4], M [M″2 (OR)i] and M′ (OR)3 (where M=Li, Na or K; M′=Al, Ga or Fe; M″=Sn; R=Me, Et, or Pri) has been detected.
