ANALYSIS OF 01ALLYLPHTHALATE IN PLAQUEHIHE RECOVERED VINYL LHlORl'ii VS ___ Introduction - Summary Oiallylphthalate (OAP) is being incorporated into mass resins produ<.>:<t at Plaquemine. Of major concern since VCM is recovered iron me process and recycled for other uses is the possible contamination of the recovery system and the R-VCM with OAP. Previous work1 on ALTC laboratory polymerizations with OAP have shown no OAP contamination of the R-VCM. Two samples of Plaquemine R-VCM (Lots 1913 and 191*) and a control sample of VCM with added OAP were submitted for analysis by gas chromatography/mass spectrometry. The sample bomb labeled lot 191* was found to be completely empty (no pressure, no water, no VCM). The lot 1913 sample wes analyzed and no OAP was found. However, this sample and the control with added OAP were found to contain significant levels of diethylphthalate. See reference. BlUlU* RRti Partial labeled total and extracted Ion currant profiles are attached to this report. The M/Z 1*9 tree* is indicative of phthalata In general. M/Z 177 of diethylpltthalato and M/Z 189 of OAP. No OAP was detectable in the lot 1913 sample (Figure 2). Diethylphthalate is present in both samples at about scan 1010. Olallylphthalatn is clnnrly present in the control sanpla (Figure 1) at about scan-11*0. Thn source of diethylphthalate is not known but could possibly bo part of the initiator solvent nakaup or an inpurity in the OAP supplied by CP Hail. cc: G. E. Thompson 0. E, Murphy R.
