P&CAM 331 in "NIOSH Manual of Analytical Methods", 2nd edition, U.S. Department of Health, Education, and Welfare, Public Health Services, Center for Disease Control, NIOSH, DHEW(NIOSH) Publication No. Methyl ethyl ketone peroxide (MEKP) is an organic peroxide, a high explosive similar to acetone peroxide. The stability of desorbed samples was investigated by reanalyzing the 1 times the target concentration desorption samples about 24 h after the original analysis. The Department of Labor also cannot authorize the use of copyrighted materials contained in linked Web sites. Table 4.6.1.Precision of the Analytical Methodfor MEK Peroxide This simulates an atmosphere of 15.3 (Section 4.2. standard ambient temperature and pressure, Standard conditions for temperature and pressure, Fibre-reinforced plastic tanks and vessels, Tert-Butyl peroxy-3,5,5-trimethylhexanoate, Occupational Safety and Health Administration. Used as an initiator for room temperature cure of unsaturated polyester resins. 4.1. Mixture with 2-propanol will form explosive peroxides during storage. Thank you for visiting our site. 4.5.1. was used to determine the SEE of ±7.41% for MEK peroxide. Dry over anhydrous magnesium sulfate and filter. 2-Propanol (IPA) and isooctane, HPLC grade. : 3105: EC-No. Because the recovery of MEK peroxide from the spiked samples was greater than 75% and the precision (1.96 SD) was less than ±25%, the detection limit of the overall procedure and reliable quantitation limit are the same. Generally, chromatographic conditions can be altered to separate an interference. The air concentration of MEK peroxide can be obtained by using the following equations: Avoid skin contact and inhalation of all chemicals. The samples were desorbed 24 h later with 2 mL of 2-propanol. Please click the button below to continue. Thermal decomposition of this compound has been studied in solution starting … Cummins, K., "Analysis of Methyl Ethyl Ketone Peroxide by HPLC and Detection by Electrochemical Reduction Using a Mercury-Gold Electrode", OSHA Analytical Laboratory, 1988. MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness. The precision of the overall procedure is determined from the storage data. Figure 3.1.3. under or a recommendation to infringe any patent or technical information Ketone peroxides, including acetone peroxide and methyl ethyl ketone peroxide, find … Normalized breakthrough times Reaction with hydrogen peroxide in the presence of nitric acid forms heat- and shock-sensitive explosive acetone peroxides. Depending on the experimental conditions, several different adducts of methyl ethyl ketone and hydrogen peroxide are known. Used as a solvent, for making other chemicals, and for production of wax from petroleum. Ignition on contact with potassium tert-butoxide. Table 4.2.Detection Limit of the Overall Procedure. 5.10.). Details. The concentration should be approximately 5 mg/mL. temperature. Elskamp, C.J., "Determination of Airborne Methyl Ethyl Ketone Peroxide", Wisconsin State Laboratory of Hygiene, Madison, WI, 1975. unpublished. Methyl Ethyl Ketone Peroxide I went to the hardware store and, next to the impulse buys, there was some acetone, tolulene, and some methyl ethyl keytone. List any potential interferences on the sample data sheet. Six samples, liquid spiked with MEK peroxide, were given to a chemist unassociated with this study. additional knowledge and experience are gained. Given orally, by inhalation, or by intraperitoneal injection, methyl ethyl ketone peroxide causes hyperemia of the lungs with petechial or gross hemorrhage in mice and rats. Aerosol generation was found to be unsuitable for preparing a standard atmosphere of MEK peroxide because it drastically changes the latter's composition. 98060 and 25561), ninhydrin reaction coil and temperature controller were used in this study. More info about absorbents, including situations to watch out for... National Oceanic and Atmospheric Administration, Ethyl Methyl Ketone Peroxide (also Methyl Ethyl Ketone Peroxide; concentration >60%), Methyl Ethyl Ketone Peroxide (concentration >60%). The detection limit of the analytical procedure is 31 ng per injection. 5.14. The precision of the analytical procedure is 0.027 for MEK peroxide dimer and 0.035 for MEK peroxide monomer. Ignition and/or explosion may occur if mixed with readily oxidizable materials. Table 4.4.1.Instrument Response to MEK Peroxide Dimer, Table 4.4.2.Instrument Response to MEK Peroxide Monomer. 4.3.). stated. R. Soc. 4.7.) XAD-4 adsorbent was selected as the sampling medium because it has previously been found to be suitable for collecting airborne MEK peroxide (Ref.
