Abstract

PURPOSE: To obtain the titled compound in a high yield, by separating a low-boiling cut from a solution containing the reacton product between an alkali metal and an N, N-disubstituted formamide, followed by recycling the low-boiling cut to the reaction stage.
CONSTITUTION: An N,N-disubstituted formamide of formulaI:(R1 and R2 are alkyl groups) is reacted with an alkali metal in the presence of CO2 gas, etc. in the reaction stage A. The low-boiling cut is separated from the solution containing the reaction product in the separation stage B, and circulated to the reaction stage A via the circulation stage C. In the product separation stage D, the objective compound of formula II is separated via the line 5 by distillation. Water, if necessary, is introduced from the line 4, and the product is isolated by extraction with a solvent. The distillation residue is fed to the cation exchange stage E, and the N,N- disubstituted oxamic acid of formula III is separated via the line 6 as an aqueous solution.
USE: Stabilizer or solvent for synthetic resins.
