Anzano, Jesus M. published the artcileChemistry practices for undergraduate students: plastic polymers characterization by gas chromatography, Safety of n-Octanol, the main research area is polymer plastic property gas chromatog.
The present study deals with the chem.-anal. characterization of plastics, specifically anal. determination of phthalates in polyvinyl chloride (PVC) and the quantification of residual styrene (S) monomer in plastic polystyrene (PS); both polymers are commonly used in food packaging. In determining phthalates, the method’s principle used, is the precipitation of the PVC polymer followed by hydrolysis of the plasticizers and the leaching of the alc. obtained in an organic phase. To study the efficiency of the reaction, dioctyl phthalate (DOP) has been used as a standard In determining S, the method used, is based on the total sample-plastic dissolution followed by the precipitation of the PS leaving behind the monomer. It does not include dilution methods. In both tests, the quant. determination is made by gas chromatog. (GC).
