Stereoselective Substitution oftrans-2-Butene for theS,S-2-Butene in Trichloro-S,S-2-buteneplatinate(II) in Acetone

Experimental and Kinetic Modeling Study of 2-Methyl-2-Butene: Allylic Hydrocarbon Kinetics.

Two experimental studies have been carried out on the oxidation of 2-methyl-2-butene, one measuring ignition delay times behind reflected shock waves in a stainless steel shock tube, and the other measuring fuel, intermediate, and product species mole fractions in a jet-stirred reactor (JSR). The shock tube ignition experiments were carried out at three different pressures, approximately 1.7, 1...

Scattering of electrons from 1-butene, H2C=CHCH2CH3, and 2-methylpropene, H2C=C(CH3)2, molecules

We report absolute grand total cross sections (TCSs) for electron scattering from 1-butene (H2C=CHCH2CH3) and 2-methylpropene (H2C=C(CH3)2) molecules, measured at electron impact energies ranging from 1 to 400 eV and from 1 to 350 eV, respectively, using a linear electron-transmission technique. The general shape of cross sections for both butene isomers looks similar. Two structures in each TC...

Capturing the Concentration Dependence of trans-2-Butene Diffusion in Silicalite-2 Zeolite with a Jump Diffusion Model

Molecular dynamics simulations of the diffusion of trans-2-butene in zeolite type MEL at 623 K have revealed an initial increase of the self-diffusivity with increasing loading, in contrast to simulation data collected for the other butene isomers. This is usually the signature of repulsive guest-guest interactions. At higher loadings, however, the concentration dependence was shown to decrease...

LINEAR ALIPHATIC UNSATURATED POLYESTERS BASED ON CIS -2- BUTENE -1,4-DIOL: SYNTHESIS AND CHARACTERIZATION

A new homologous series of linear aliphatic polyesters, such as poly (cis-2- butenylene carboxylate)S, PBms (m is the number of methylene groups in the acid component, m=2-8 have been synthesized by direct polyesterification reactions in anisole, as solvent. FT-IR, 400 MHz H- NMR, C-NMR and elemental analysis were used to establish the structure of polyesters. Molecular weight distributi...
