AN ATTEMPT TO MEASURE THE AFFINITY OF SOME MODEL ORGANIC COMPOUNDS FOR PVC USING A GAS CHROMATOGRAPHIC TECHNIQUE

AN ATTEMPT HAS BEEN MADE TO RATIONALIZE THE AFFINITY OF PVC FOR VARIOUS TYPES OF BITUMINOUS BINDERS BY STUDYING THE BEHAVIOR OF MODEL COMPOUNDS INJECTED INTO A GAS CHROMATOGRAPH IN WHICH THE COLUMN WAS PACKED WITH PVY POWDER. THE RESULTS APPEARED CONSISTENT WITH THE KNOWN COMPATIBILITY BETWEEN PVC AND BITUMINOUS BINDERS AND DEMONSTRATE THAT A CONSIDERABLE AFFINITY EXISTS BETWEEN PVC AND HYDROCARBONS CONTAINING FUNCTIONAL GROUPS AND ALSO STRONGLY AROMATIC COMPOUNDS WHICH PREDOMINATE IN COKE-OVEN TAR. THIS APPEARS TO BE INFLUENCED BY THE CONFIGURATION OF MOLECULES, THE PRESENCE OF NON-REACTIVE GROUPS IN THE MOLECULE DIMINISHING THE AFFINITY FOR PVC. THESE RESULTS SUGGEST THAT PVC POWDER MIGHT BE USED IN GAS CHROMATOGRAPHY AS AN AGENT FOR THE INDENTIFICATION OF CERTAIN COMPONENTS OF MIXTURES OF HYDROCARBONS BY THEIR SELECTIVE RETENTION ON A SMALL LOOP FILLED WITH THE POWDER. IT WAS SHOWN THAT AROMATIC COMPONENTS CAN BE IDENTIFIED IN MIXTURES OF AROMATICS, N-, ISO- AND CYCLOPARAFFINS. IT APPEARS TO BE AS EFFECTIVE, IN THIS REGARD, AS SOME ACCEPTED MOLECULAR SIEVES, WITH THE ADVANTAGE OF CHEAPNESS, AND REQUIRES NO TREATMENT PRIOR TO USE. IT'S USE FOR THIS PURPOSE IS GOVERNED BY THE LIMITATION TO USE THE MATERIAL AT TEMPERATURES LESS THAN 100 DEGREES C THE MOST GENERALLY SUITABLE MAXIMUM TEMPERATURE FOR PVC IN THESE INVESTIGATIONS WAS FOUND TO BE 70 DEGREES C.
