Isolable 1-Butene Copper(I) Complexes and 1-Butene/Butane Separation Using Structurally Adaptable Copper Pyrazolates
(Wiley-VCH Verlag, 2020-11-26)
Non-porous small molecule adsorbents such as {[3,5-(CF3)2Pz]Cu}3 (where Pz=pyrazolate) are an emerging class of materials that display attractive features for ethene−ethane separation. This work examines the chemistry of ...
Comparative kinetics of the 3-Buten-1-ol and 1-Butene reactions with OH radicals: a density functional theory/RRKM investigation
(American Chemical Society, 2015-03-18)
The compared kinetics of the reactions of unsaturated alcohols and alkenes with OH radicals is a topic of great interest from both the theoretical chemistry and the atmospheric chemistry points of view. The enhanced ...
Kinetic evaluation of the set of reactions in the selective hydrogenation of 1-butyne and 1,3-butadiene in presence of n-butenes
(American Chemical Society, 2013-05-25)
The selective hydrogenation in the liquid phase of 1-butyne and 1,3-butadiene in the presence of n-butenes over a commercial Pd/Al 2O3 egg-shell catalyst has been studied. Although hydrogenation of the n-butenes and their ...
Crystallization behavior of random ethylene-butene copolymers modified with organic peroxide
(Elsevier Science, 2012-01-02)
The effect of molecular cross-linking on the crystallization of random ethylene-1-butene copolymers obtained from hydrogenation of model polybutadiene was studied by means of differential scanning calorimetry. The copolymers ...
Effect of radiation-induced oxidative degradation on the non-isothermal crystallization of ethylene-butene copolymer
(Elsevier, 2019-12)
A random ethylene–butene copolymer was irradiated with high ionizing energy in environments with different oxygen concentration. The non-isothermal crystallization process of the materials was studied by differential ...
Mechanism and molecular weight model for thermal oxidation of linear ethylene-butene copolymer
(Elsevier, 2001-12)
The mechanism of thermooxidative degradation at 80°C of a narrow distribution linear ethylene-butene copolymer has been described by determining the chemical modifications and molecular weight distribution changes occurring ...
Kinetic study of the hydrogenation and hydroisomerization of the n-butenes on a commercial palladium/alumina catalyst
(American Chemical Society, 2003-04-09)
A kinetic investigation of the vapor-phase hydrogenation and hydroisomerization of 1-butene and cis- and trans-2-butene is presented. This investigation is aimed at validating a practical set of rate equations. The experiments ...
Performance of ferrierite promoted with tungsten or boron species during the linear butene skeletal isomerization
(Research Trends, 2006-12)
Ammonium and potassium ferrierites were modified with tungsten or boron species using incipient wetness and wet impregnation or ion exchange. Catalytic behavior during the linear butene skeletal isomerization was measured ...
Selective hydrogenation of 1,3-butadiene: Improvement of selectivity by using additives
(Elsevier Science Sa, 2004-05)
The objective of this work is to evaluate the behavior of isoprene as an additive to improve selectivity in the selective hydrogenation of 1,3-butadiene from 1-butene-rich cuts. To this end, the liquid-phase hydrogenation ...
The use of SSA fractionation to detect changes in the molecular structure of model ethylene–butene copolymers modified by peroxide crosslinking
(Elsevier, 2009-07)
Four model ethylene–butene copolymers of different molecular weights modified with various concentrations of peroxide were analyzed by a DSC based successive self annealing method. The original copolymers had the same intra ...
