Abstract
1352763 Sebacic acid diesters BADISCHE ANILIN- & SODA-FABRIK AG 11 Aug 1971 [12 Aug 1970] 37676/71 Heading C2C [Also in Division C7] Sebacic acid diesters of C 4-12 alcohols, e.g. di-2-ethylhexyl sebacate, are made by electrochemical condensation of the corresponding adipic acid monoesters, e.g. mono-2-ethylhexyl adipate, in methanolic solution, the current flow through the electrolytic cell being intermittently stopped, e.g. for periods of 2 to 60 seconds at intervals of 1 to 30 minutes, and the electrodes being short-circuited. The solution may also contain 5 to 20% of methylethyl ketone or cyclohexanone, and 0À5 to 2% of acetic acid; the acidic solution may be partially neutralized by adding sodium (bi)-carbonate or methoxide. The C.D. may be 5 to 50 A/dm.<SP>2</SP> The anode may be of Pt, Pt-Rh, Pt-Ru, Pt-Ir, Au, Au-Pt, Au plated or platinized Ti or Ta or Ru oxide; the cathode may be of Pt, stainless steel, Ni or Ti. The cell may have permable vibrating pairs of electrodes, or impermeable non-vibrating electrodes.
