CH2CH2OH radicals have been studied at room temperature by using a pulse radiolysis/kinetic absorption technique.The ultraviolet spectrum lies in the range 210-265 nm with a maximum absorption cross section of 2.0*10-18 cm2 molecule-1 at 210 nm.This technique has also been used to study the overall kinetics of the self-reaction of these radicals: 2CH2CH2OH (+M) --> (CH2CH2OH)2 (+M) (7a); 2CH2CH2OH (+M) --> CH3CHO + CH3CH2OH (7b), while product studies using gas chromatography have yielded information on the reaction pathways.A value of k7 = 5.6(+/-1.0)*10-11 cm3 molecule-1 s-1 and a branching ratio of k7a/(k7a + k7b) 0.88 have been measured at room temperature.
Carbodeoxygenation of biomass: The carbonylation of glycerol and higher polyols to monocarboxylic acids

Glycerol is converted to a mixture of butyric and isobutyric acid by rhodium- or iridium-catalysed carbonylation using HI as the co-catalyst. The initial reaction of glycerol with HI results in several intermediates that lead to isopropyl iodide, which upon carbonylation forms butyric and isobutyric acid. At low HI concentration, the intermediate allyl iodide undergoes carbonylation to give vinyl acetic acid and crotonic acid. Higher polyols CnH n+2(OH)n are carbonylated to the corresponding C n+1 mono-carboxylic acids. Copyright
Synthesis and physical properties of ferrocene derivatives (XXV) liquid crystallinity of 1,3-disubstituted ferrocene derivatives
Nakamura, Naotake,Kagawa, Shinya
experimental part, p. 150 - 159 (2012/01/03)
Liquid crystallinity of 1,3-disubstituted ferrocene derivatives was studied by DSC and polarizing microscope. The name of the derivatives is 1,3-bis[-[4-(4-methoxyphenoxycarbonyl)phenoxy]alkyloxycarbonyl]ferrocene. Nine members from n = 2 to 10 were synthesized (n is carbon number of alkyl chain in the sample). All samples except n = 2 and 4 exhibited monotropic nematic liquid crystalline phase. In addition, smectic X (not yet completely identified) was also observed in n = 8 and 10. Liquid crystalline phase transition phenomena were discussed from a viewpoint of molecular shape.
