Characterization and DFT studies of cis, trans and vinyl derivatives of 1,4-butadiene using C20 in different temperatures
In this research of cis, trans and vinyl monomeric derivatives of 1,4-butadiene were studied using C20 in different temperatures by Functional density theory (DFT). To this purpose, the materials were firstly optimized geometrically, then the calculations of the thermodynamic parameters were performed on all of them. In the following, changes in parameters of energy...
متن کاملThe reactivity of 1,3-butadiene with butadiene-derived popcorn polymer.
Adiabatic calorimetry performed on butadiene-derived popcorn polymer samples from industrial facilities has revealed exothermic behavior accompanied by non-condensible gas production, indicative of possible decomposition, at elevated temperatures. In the presence of low concentrations of 1,3-butadiene, reactivity is observed at temperatures of 60-70 degrees C; that is, 20-30 degrees C below tho...
متن کامل(η4-s-cis-1,3-Butadiene)tetracarbonylchromium(0)
In the title complex, [Cr(C(4)H(6))(CO)(4)], the Cr(0) atom shows a distorted octa-hedral environment from four C atoms of the carbonyl ligands and the two π-bonds of the s-cis-1,3-butadiene ligand. The complex has an approximate non-crystallographic mirror symmetry m passing through the chromium atom, two carbonyl ligands and the mid-point of the central C-C bond of the s-cis-1,3-butadiene lig...
متن کاملRedetermination of (η4-s-cis-1,3-butadiene)tricarbonyliron(0)
The crystal structure of the title compound, [Fe(C(4)H(6))(CO)(3)], was previously reported by Mills & Robinson [Acta Cryst. (1963) ▶, 16, 758-761]. The compound crystallizes in the centrosymmetric space goup Pnma with the complex located on a mirror plane. The redetermination of this structure at 100 K yielded almost equilibrated C-C bond lengths within the butadiene ligand according to a meta...
متن کاملsynthesis of ethylene bis-stearamide for acrylonitrile-butadiene-styrene polymer
ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...
