Hydrogenation of 1,5,9-Cyclododecatriene in a Three-Phase System in the Presence of Nickel Nanoparticles Supported on NаX Zeolite

The hydrogenation of 1,5,9-cyclododecatriene in the presence of nanostructured Ni catalysts, supported with NaX zeolite, in a flow-through reactor at atmospheric hydrogen pressure was investigated. Nickel nanoparticles on the support surface were prepared by chemical reduction of the precursor (NiCl2) with NaBH4 and NH2NH2. The effect exerted on the yield of hydrogenation products by the nominal residence time of the gas phase in the reaction zone and by the process temperature was considered, and the catalyst operation life was analyzed. The catalysts showed high activity and allowed preparation of cyclododecane in ~100% yield at a process temperature of up to 160°С.

Colloidal and nanosized catalysts in organic synthesis: XV. Gas-phase hydrogenation of alkenes catalyzed by supported nickel nanoparticles

Gas-phase hydrogenation of alkenes and their derivatives, catalyzed by nickel nanoparticles supported on zeolite or silica gel support occurs at 150–250°С and an atmospheric hydrogen pressure and results in a high conversion. The selectivity of the hydrogenation depends on the amount of hydrogen: at a low diene (triene)–hydrogen ratio, selective hydrogenation of one multiple bond in the substrate is possible.

Bimetallic Ru-Sn nanoparticle catalysts for the solvent-free selective hydrogenation of 1,5,9-cyclododecatriene to cyclododecene

(Figure Presented) Tin(n)y catalysts: Bimetallic RuSn supported nanoparticle catalysts (see picture; Ru green, Sn blue, O red), prepared from the carbonyl-cluster precursors [Ru4 (μ4-SnPh) 2(μ-SnPh2)4-x(CO)12-x] (x = 0, 2, 3, 4) are shown to be active catalysts for the highly selective hydrogenation of 1,5,9-cyclododecatriene to cyclododecene under mild conditions.

Selective hydrogenation of cyclododecatriene to cyclododecene

A method for the production of cyclododecene (CDEN) by selective gas-phase hydrogenation of cyclododecatriene (CDT) and/or cyclododecadiene (CDD) involves using a solid-bed reactor in which the bed number (Bo) is more than 100 (Bo = product of average flow rate and length of flow tube divided by axial diffusion coefficient).
