  Reforming of n-hexane in presence of [1,2-bis(salicylidene amino)-phenylene]–zirconium complex chemically bound on modified silica gel support

  摘要：

  The heterogeneous catalyst consisting of [1,2-bis(salicylidene amino)-phenylene]-zirconium complex chemically bound on modified carbamate silica gel was synthesised and the reforming of n-hexane was studied in a rocking type batch reactor system. The isomerization and cyclization of n-hexane occurs in presence of this catalyst at low temperatures (120-190degreesC) with high conversion (72%) in an atmosphere of nitrogen. The analysis of the reaction products suggests the occurrence of isomerization (forming 2-methylpentane (2-MP) and 3-methylpentane (3-MP)) and cyclization (forming methyl cyclopentane (MCP) and cyclohexane (CH)). There is no formation of dibranched isomers and of aromatization reaction (forming benzene and toluene), dehydrogenation reactions (forming alkenes) and cracking reactions (forming C-1-C-5 compounds).

  A heterogeneous catalyst consisting of [1,2-bis(salicylidene amino)-phenylene] zirconium complex chemically bonded to carbamate-modified silica gel catalyst has been synthesized and the oxidation of n-heptane using molecular oxygen was studied in a batch reactor system. The study was conducted in the temperature range of 160-200degreesC. The product distribution was found to be entirely different from that reported in literature. Cyclohexanone was the only oxygenated product formed, the rest being isomerized products of hexane and heptane (2-methylpentane. methylcyclopentane, 4-methyl, 1-pentene and toluene). Experiments suggest that in the oxidation of heptane carried out in this work, reforming reaction occurred first and cyclohexane formed undergoes oxidation to give cyclohexanone. The thermogravimetric analysis (TGA) shows that the catalyst starts breaking only beyond 383 degreesC. (C) 2004 Elsevier B.V. All rights reserved.
