Cyclododecane solubility

This complex is selectively soluble in perfluorinated solvents and catalyzes the hydrogenation of e.g. cyclododecene under FBS-conditions at 45 °C (H2,1 atm) affording cyclododecane (19) in 94% yield Eq. (10). 

Oximation of cyclododecane, a solid-liquid reaction, was studied by Janakiraman and Sharma (1985) by reacting finely ground particles of cyclododecanone (CD) with aqueous hydroxylamine sulfate (HAS) in a mechanically agitated contactor, with and without microparticles of carbon. The carbon particles are not catalysts but strongly adsorb the solid reactant (which is otherwise only sparingly soluble in the aqueous phase) and transport it to the aqueous bulk, where reaction occurs at an enhanced rate. The reaction was carried out at 2 °C, at an agitator speed of 1200 rpm, and a ketone holdup of 0.04 g/cm. Carbon microparticles of two sizes, 1.7 p and 4.33 p, were used, and volumetric rates (mol/scm aqueous phase) were determined at different microphase loadings for each size. These are presented in Table 23.2. 

The shortest-term coatings are fixatives protecting a fragile element of an object during a potentially damaging treatment, for instance the use of a cyclododecane/Paraloid B-72 coating protecting water-soluble ink on paper...
