DETECTION OF VOLATILES EVAPORATING FROM A PLASTIC CONTAINER AFTER BEING MICROWAVED.

摘要

A coextruded plastic container was cut up and placed into a glass vial which was then sealed. The vial was suspended over the microwave floor and microwaved on full power for periods of time ranging from 3 to 7 minutes. The temperature the plastic surface experienced over the time range was approximated with the use of melting point standards waxes. Five major components were detected and quantified in the headspace of the vial using a gas chromatograph. The quantity of each component increased as the microwaving time increased. Using a mass spectrometer the five components were tentatively identified; four of the components were identified as hydrocarbons and the fifth component was positively identified as butylated hydroxytoluene.
