Abstract

Lead tetraalkyls are formed cathodically by electrolysis in a diaphragm cell using a lead cathode, a catholyte comprising (a) a C1-C10 alkyl halide other than fluoride, (b) a current-carrier having a higher reduction potential than component (a) and giving a conductivity of at least 0.001 ohm-1 cm-1 and consisting of at least one C1-C18 tetraalkyl ammonium more halide other than fluoride, and (c) 1 to 20 moles per mole of current-carrier of water and/or one or more C1-C4 alkanols, and an anolyte comprising a solution of a current-carrier as in (b) above in an inert solvent having a reduction potential at least as high as the alkyl halide (a) above and an oxidation potential higher than the current-carrier. The anode may be of any suitable material including lead but preferably is resistant to the anodically evolved halogen and may be of graphite, Pt, or platinized Ti or Ta. The diaphragm may be of parchment paper which is preferably soaked before use with water or a solution of a tetraalkyl ammonium monohalide to increase its porosity and conductivity. The catholyte may also include an inert solvent for the alkyl halide and current-carrier, the solvent having a reduction potential higher than the alkyl halide and an oxidation potential higher that the current-carrier. Suitable catholyte inert solvents are alkanonitriles having C1 to C5 alkyl groups. The anolyte solvent may be water, a C1 to C4 alkanol or an alkanonitrile as for the catholyte. Electrolysis may be effected at a temperature of 10 to 80 DEG C with a cathode current density of 0.05 to 0.5 amp./cm2, and may be performed batchwise or with continuous circulation of catholyte and anolyte through the respective cell compartments. As shown, a cylindrical glass cell 10 provided with a heat-exchange jacket 24 houses a cylindrical platinum anode 11, a tubular parchment paper diaphragm 14 and an anode of lead shot 16 and lead rod 15 contained within a nylon mesh sleeve 17. The tetraalkyl lead is extracted from the catholyte by fractional or steam distillation or by diluting the catholyte with a large excess of water, extracting the tetraalkyl lead with a solvent such as pentane and separating off the solvent by fractional distillation under reduced pressure.
