Ethyl Radical

Methyl ethyl ketone has been photolyzed at temperatures between 25° and 240 °C., at varying pressures and intensities. Azomethane has also been photolyzed in the presence of methyl ethyl ketone. It is concluded that the ratio of disproportionation to recombination for a methyl and an ethyl radical is of the order of 0.04. The activation energy for the abstraction of hydrogen from the ketone by methyl is 7.4 ± 0.1 kcal., and by ethyl it is 8.0 ± 0.1 kcal.

Free Radical Initiation

Monomeric styrenes are demonstrated as excellent embedding media for electron microscopy. Monomeric styrene has extremely low viscosity and low surface tension (less than 1) affording extremely rapid penetration into the specimen. Spurr's Medium based on ERL-4206 (J.Ultra. Research 26, 31-43, 1969) is viscous, requiring gradual infiltration with increasing concentrations. Styrenes are soluble in alcohol and acetone thus fitting well into the usual dehydration procedures. Infiltration with styrene may be done directly following complete dehydration without dilution.Monomeric styrenes are usually inhibited from polymerization by a catechol, in this case, tertiary butyl catechol. Styrene polymerization is activated by Methyl Ethyl Ketone peroxide, a liquid, and probably acts by overcoming the inhibition of the catechol, acting as a source of free radical initiation.Polymerization is carried out either by a temperature of 60°C. or under ultraviolet light with wave lengths of 3400-4000 Engstroms; polymerization stops on removal from the ultraviolet light or heat and is therefore controlled by the length of exposure.
