Forty grams of unsaturated polyester (see above, Section 2.4.2.1), 26.7 g of styrene, and 10 mg of hydroquinone are weighed into a plastic beaker. The mixture is stirred and slightly warmed, if necessary, until complete dissolution. Then, at room temperature, 0.25 mL Co(II) 2-ethylhexanoate (note a below) and 1.0 mL of 2-butanone peroxide (MEKP, note b below) are added to the stirred mixture. The mixture gels after a 10-20-min period (stir during this period) and solidifies after ca. 1 h (Scheme 2.55)424. 

Notes (a) Cobalt(II) 2-ethylhexanoate, 65% mass solution in mineral spirits (b) 2-butanone peroxide, ca. 32% mass solution in dimethyl o-phthalate. 

By analogy, this dimeric 2-butanone peroxide and the corresponding trimer probably contribute largely to the high shock-sensitivity of the commercial MEK peroxide mixture, which contains these and other peroxides [1,2]. 

Existing and proposed methods of evaluating transportation hazards of organic peroxides exposed to impact, explosive shock or thermal singe stimuli were reviewed, and a hazard classification system proposed [1]. Commercial 2-butanone peroxide ( MEK peroxide ) as a 40% solution in dimethyl phthalate was previously... 

A highly selective method for determination of lipid hydroperoxides is based on the oxidation of ferrocenecarboxylic acid (201) to the corresponding ferrocenium compound (202), as shown in equation 69, followed by amperometric reduction of this complex with a GCE set at —100 mV vs. SCSE, in phosphate buffer at pH 5.5. The method is insensitive to dissolved oxygen and no interference is observed, either from reductors such as ascorbic acid (22) or uric acid (29) nor from other hydroperoxides such as H2O2 and f-BuOOH at the 1 xM concentration level. At this concentration, a slight interference is observed for cumyl hydroperoxide (27) and 2-butanone peroxide (46 4- 47). The LOD...

Peroxide explosions are usually caused by heat, shock, impact, or catalysts, but the possibility of spontaneous explosions must not be left out of account, even with peroxides that are normally considered to be harmless. Among the most important protective measures in work with these substances is to wear protective glasses many organic peroxides (tert-butyl hydroperoxide, cumyl hydroperoxide, cyclohexanone peroxide, 2-butanone peroxide, diacetyl peroxide) cause serious injury on entry into the eye.315 If such an accident happens, the eye should be bathed at once with water or, better, 2% sodium hydrogen carbonate solution oily media must not be used.
