Abstract:

Abstract A chromium incorporated mesoporous silicate structured Cr/MCM-41 type catalyst was synthesized following a one-pot hydrothermal route and tested in dehydrogenation of isobutane to isobutene in a Pd membrane reactor. Characterization results of the catalyst proved that it had ordered pore structure with a narrow pore size distribution. This catalyst showed quite high activity for the dehydrogenation of isobutane. Membrane reactor tests performed at 823 K proved the advantages of in-situ removal of produced hydrogen from the reaction zone through the membrane, on isobutene yield. In fac

Abstract:

Four V-Mo-O mixed metal oxides were prepared, characterized and tested for the selective oxidation of isobutane in the temperature range 350-550?C, at atmospheric pressure. Isobutane was mainly oxidized to isobutene and carbon oxides. The systems with low vanadium contents showed low activities but high isobutene selectivities, while the systems with high vanadium contents showed high activities with high carbon oxides selectivities. The effects of temperature, contact time and the molar ratio iso-butane to oxygen on the conversion of isobutane and the selectivity of the oxidation were studied

Abstract:

Methyl methacrylate (MMA) has emerged as an essential industrial monomer. However, the toxic by-production and shortage supply of MMA in the global market has gained great attention. Herein, a one-step synthesis to produce MMA from isobutene via a direct oxidative esterification process has been demonstrated to curb the aforementioned downsides. Thermodynamic analysis via Gibbs free energy minimization method proved the feasibility of this route via the equilibrium constant. Despite tert-butanol and isobutane showed higher equilibrium constant than isobutene, they should be avoided. Isobutane

Abstract:

A literature survey on the homogeneous gas-phase oxidation of light alkanes shows that despite a rather high number of papers there are still, even in the case of isobutane, an important number of unresolved questions, which makes the writing of a reaction scheme rather difficult. To obtain more reliable experimental data, we have studied the homogeneous gas-phase oxidation of isobutane in a conventional static system, at 310 and 340 °C and subatmospheric pressure. This investigation is chiefly aimed at identifying and measuring the major primary products of the reaction. A chain radical schem

Abstract:

ABSTRACT Isobutene is an important commercial chemical used for the synthesis of butyl rubber, terephthalic acid, specialty chemicals, and a gasoline performance additive known as alkylate. Currently, isobutene is produced from petroleum and hence is nonrenewable. Here, we report that the Saccharomyces cerevisiae mevalonate diphosphate decarboxylase (ScMDD) can convert 3-hydroxy-3-methylbutyrate (3-HMB) to isobutene. Whole cells of Escherichia coli producing ScMDD with an N-terminal 6×His tag (His6-ScMDD) formed isobutene from 3-HMB at a rate of 154 pmol h−1 g cells−1. In contrast, no isobuten

Abstract:

A process was designed for etherification of glycerol with isobutene based on latest results of kinetic and thermodynamic study. A continuous stirred tank reactor was employed to carry out the reaction. Fresh glycerol was used to extract mono-ethers (ME) of glycerol in the reaction product and then returned to the reactor. Residual glycerol and ME were recovered by water washing and distillation. Isobutene and isobutene dimers were separated from high-ethers in a side draw distillation column. The new process was optimized, and a product yield of 97 wt% was obtained.

Abstract:

The novel compounds [Me4N][MeCO2{B(C6F5)3}] and [Me4N][MeCO2{B(C6F5)3}2] are prepared and characterized spectroscopically and crystallographically. The compounds are salts of the unisolable acids MeCO2H·B(C6F5)3 and MeCO2H·2B(C6F5)3, respectively, which are sufficiently strong that they can protonate isobutene and initiate its carbocationic polymerization. The 1:1 adduct contains a conventional, monodentate acetate ion coordinated to the B(C6F5)3, while the 2:1 adduct contains a bridging acetate ligand.Key words: weakly coordinating anions, carbocationic polymerization, isobutene, polyisobuten

Abstract:

The chromium oxide catalysts supported on silicalite-1 zeolite (Cr/S-1) with a Cr content between 0.5% and 7% were synthesized via an incipient wetness method. The catalysts were characterized by XRD, N2 adsorption, TEM-EDX, UV-vis, DRIFTS, 29Si MAS NMR, XPS, H2-TPR, and NH3-TPD. The optimum 3%Cr/S-1 catalyst with 3%Cr is more active and stable than SBA-15-supported one with the same Cr content, which is a consequence of a higher content of Cr6+ in the fresh 3%Cr/S-1 catalyst and a higher content of Cr6+ retained on the former catalyst during the reaction. The 3%Cr/S-1 catalyst affords an isob
