Abstract

1,210,518. Electrolytic production of tetraalkylammonium hydroxides. MONSANTO CO. 13 Dec., 1967 [19 Dec., 1966], No. 56529/67. Heading C2C. [Also in Division C7] An aqueous solution of a tetraalkylammonium hydroxide is prepared in an electrolytic cell divided by a cation permseleetive membrane into anolyte and catholyte chambers from an anolyte feed comprising an aqueous solution containing 10 to 50% by weight of the corresponding tetraalkyl ammonium salt having an anion which does not provide toxic fumes at the anode, the catholyte feed being water, the rate of feed per hour per ampere of the electrolysing current being 1À5 to 4À0 Ibs. for the anolyte and 1À4 to 4À0 lbs. for the catholyte. The anolyte salt may be a sulphate, bisulphate, alkylsulphate, nitrate, carbonate or bicarbonate or a mixture of these and quaternary ammonium group is typically formed by C 1 to C 3 alkyl radicals. As described tetraethylammonium hydroxide is formed in the catholyte from a mixture of tetraethylammonium sulphate and tetraethyl ammonium ethylsulphate, the temperature being kept below 50‹ C. and the anolyte pH being 1À4.
