Abstract: WATER INSOLUBLE IMPURITIES ARE SEPARATED FROM AN AQUEOUS MIXTURE OF AN ALKALI METAL SALT OF AN AROMATIC CARBOXYLIC ACID CONTAINING SUCH IMPURITIES IN SUSPENSION BY CONTACTING THE AFORESAID MIXTURE WITH A CATIONIC ACRYLAMIDE COPOLYMER, E.G. A QUATERNARY SALT OF A VINYLPYRIDINE/ACRYLAMIDE COPOLYMER. FILTRATION AND SETTLING TIME RATES ARE SIGNIFICANTLY IMPROVED BY THE USE OF SAID CATIONIC ACRYLAMIDE COPOLYMERS.

Abstract: AN ALKALI METAL SALT OF AN AROMATIC CARBOXYLIC ACID IS RECRYSTALLIZED FROM A WATER SOLUTION IN THE PRESENCE OF AN ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALCOHOLS, ESTERS AND KETONES. THE RECRYSTALLIZED SALT IS THEREAFTER UTILIZED IN A DISPROPORTIONATION PROCESS WHEREIN THE ALKALI METAL SALT IS CONVERTED TO AN AROMATIC POLYCARBOXYLATE CONTAINING AT LEAST ONE ADDITIONAL CARBOXYLATE GROUP.

Abstract: OLEFINICALLY UNSATURATED COMPOUNDS CONTAINING AT LEAST TWO CARBON TO CARBON DOUBLE BONDS IN CONJUGATION ARE CONVERTED TO ESTERS BY CONTACTING WITH CARBON MONOXIDE AND AN ALCOHOL CONTAINING UP TO 3 HYDROXYL GROUPS IN THE PRESENCE OF A BRIDGED ORGANO DIRHODIUM COMPLEX CATALYST. THE ESTERS PRODUCED HAVE UTILITY IN THE PRODUCTION OF POLYMERS.
