Diacetylene Methylcyclopentane ether Group C chemicals consist of monomers which form peroxides that can initiate explosive polymerization. Inhibited monomers should be tested before use and discarded after 12 months. Uninhibited monomers should be discarded 24 hours after opening. Table C.3 Group C Chemicals – Acrylic acid Styrene Acrylonitrile Tetrafluoroethylene Butadiene Vinyl acetate Chloroprene Vinyl acetylene Chlorotrifluoroethylene Vinyl chloride Methyl methacrylate Vinyl pyridine General Guidelines Solvents containing inhibitors should be used whenever possible. All peroxide forming solvents should be tested prior to distillation. Peroxide forming solvents should be purchased in limited quantities. Peroxide forming solvents should be marked with the purchase date and the date opened. Peroxide forming solvents should be sealed tightly and stored away from light and heat. Periodic testing should be done on opened containers and the results marked on the containers. Testing Obtain test strips for the of 0-100 ppm peroxide. Record the test results on the bottle. If the test results are 100 ppm or greater, contact REM (765-49-40121) for proper disposal.
