Abstract
Abstract A vacuum trapping apparatus was developed for the collection of volatiles and for the determination of rates of volatilization of DDVP from Vapona-PVC resin formulations. More than 99% of the total volatiles was collected by this apparatus. To determine the total content of DDVP in the resin four extracting solvents were tested. Acetone was the most effective solvent. An improved GLC procedure was developed for the quantitation of DDVP. Several liquid phases were compared and optimum chromatographic parameters were examined. Tailing peaks were obtained with DC-11 and DC-11 + Epon 1001. Carbowax 20M gave symmetrical peaks, but optimum column efficiency was obtained on a 7% neopentyl glycol adipate column. The relative standard deviation for the analysis of DDVP by GLC was ±1.8%.
