Abstract: A CATALYST CONTAINING METALLIC PALLADIUM DEPOSITED ON AN ACIDPROOF CARRIER FOR USE IN THE HYDROGENATION AND DECHLORINATION OF DICHLOROACETIC ACID AND/OR TRICHLOROACETIC ACID TO PRODUCE MONOCHLOROACETIC ACID AND/OR ACETIC IS REGENERATED. TO THIS EFFECT, THE POISONED CATALYST CONTAINING MOISTURE IN FORM OF WATER AND/OR ACETIC ACID AND/OR MONOCHLOROACETIC ACID IS TREATED WITH CHLORINE GAS IN AN ACID MEDIUM, AT TERPERATURES OF BETWEEN 20 AND 200*C., WHEREBY THE METALLIC PALLADIUM IS OXIDIZED TO PALLADIUM CHLORIDE; RESIDUAL CHLORINE IS EXPELLED BY MEANS OF AN ENERT GAS; AND THE OXIDIZED CATALYST IS SUCCESSIVELY TREATED WITH A REDUCING AGENT TO RE-EFFECT REDUCTION OF THE PALLADIUM CHLORIDE TO METALLIC PALLADIUM.

Abstract: ISOLATION AND RECOVERY OF ACETYLENE FROM AN ACETYLENECONTAINING GAS MIXTURE BY INTIMATELY CONTACTING THE SAID GAS MIXTURE WITH A SOLVENT, THAT IS CXAPABLE OF SELECTIVELY EXTRACTING AND ABSORBING THE ACETYLENE, AND EXPELLING THE ABSORBED ACETYLENE FROM THE SOLVENT. THE ACETYLENE IS MORE PARTICULARLY ISOLATED AND RECOVERED WITH THE USE OF A SOLVENT SUBSTANTIALLY CONSISTING OF DIMETHYLPHOSPHINE OXIDE, METHYLETHYLPHOSPHINE OXIDE OF DIETHYLPHOSPHINE OXIDE.

Abstract: COLLECTED IN ONE OR MORE CONDENSERS; A PORTION OF HYDROCYANIC ACID IS CONTINUOUSLY REMOVED THEREFROM, RECYCLED TO THE HEAD OF THE CONDENSER(S) AND SPRAYED THEREINTO.

IMPROVED PRODUCTION OF AQUEOUS HYDROCYANIC ACID BY SUBJECTING FORMAMIDE TO A CLEAVAGE REACTION UNDER REDUCED PRESSURE AND AT ELEVATED TEMPERATURES, WHEREIN THE HYDROCYANIC ACID-CONTAINING CLEAVAGE GAS, WHICH IS FREED FROM AMMONIA AND COOLED, IS COMPRESSED SUBSTANTIALLY TO ATMOSPHERIC PRESSURE AND LIQUEFIED. THE COMPRESSED CLEAVAGE GAS IS MORE PARTICULARLY LIQUEFIED IN ONE OR MORE CONDENSERS, WHICH ARE ARRANGED IN UPRIGHT POSITION AND SERIES-CONNECTED TOGETHER; THE RESULTING AQUEOUS HYDROCYANIC ACID IS
