Abstract: A PROCESS IS DESCRIBED FOR THE ISOLATION OF CARBON DIOXIDE AND ACETYLENE FROM A CRACKED GAS BY MULTISTAGE WASHINGS USING ACETONE AND DIMETHYLFORMAMIDE, WHEREIN THE CRACKED GAS IS FIRST WSASHED WITH ACETON, THEN ACETYLENE, CARBON DIOXIDE AND ETHYLENE ARE EXPELLED FROM THE
ACETONE SOLUTION BY RELEASE FROM PRESSURE AND THE ACETYLENE IS WASHED OUT OF THIS MIXTURE WITH DIMETHYLFORMAMIDE.-
