Abstract

Synthesis of diamino-1,X-cyclododecanes, X being the posn 4,5 or 6, from cyclododecatriene-1,5,9 by a chain of operations consisting of (a) selective epoxidation into cyclododecene-9-diepoxide-1,2,5,6, pref in two stages: (b) Hydrogenation to mixed isomeric cyclododecone diols pref in the presence of a Ni based catalyst at 120-180 degrees C under 100 bars pressure, (c) Oxidation into cyclodeceadiones pref by a H2SO4 soln of chromic acid at 5-40 degrees C, (d) Oximation by a hydroxylamine salt and (e). Reduction to cycloddecanes diamines pref in the presence of alkali metals and lower alcohols. The diamines react with dioxides to form polyamides having remarkable resistance to heat and oxidation with a selectively low fusion point.
