Abstract

1,265,106. Alkali metal malonates. RHONE POULENC S.A. 31 July, 1970 [4 Aug., 1969; 28 May, 1970], No. 37216/70. Heading C2C. Alkali metal malonates of the formula where R is a hydrogen atom or an alkyl C 1-6 radical and M and M<SP>1</SP> each represent an alkali metal atom at least one of M and M<SP>1</SP> being a potassium atom, are prepared by reacting carbon monoxide with a mixture of an alkali metal salt of an acid of the formula and an alkali metal carbonate, the alkali metal of at least one of the organic acid salt and the carbonate being potassium. Preferably the pressure of the carbon monoxide is 20 to 500 bars, the molar ratio of the alkali metal salt to the alkali metal carbonate is 0À1 : 1 to 10: 1, and the temperature is 200‹ to 400‹ C.
