An ultrahigh molecular weight polyethylene (UHMWPE) fibrous adsorbent with amidoxime (AO) groups, denoted as AO-UHMWPE, was prepared by preirradiation-induced graft copolymerization of acrylonitrile (AN) and acrylic acid (AA) on UHMWPE fibers, followed amidoximation. The chemical structure, thermal stability, mechanical strength were evaluated means Fourier transform infrared spectrometry, thermogravimetric analysis, tensile tests, respectively. adsorption behaviors the AO-UHMWPE fiber...
A CaO/C composite, a new solid base catalyst, was prepared and served as convenient efficient heterogeneous catalyst for synthesis of DMC from methanol propylene carbonate. Compared with pure CaO, the shows same basic properties high performance. In addition, which is easily recovered, can be reused little deactivation, if suitable particle size chosen.
Gamma-ray (γ-ray) irradiation was introduced into zeolite synthesis. The crystallization process of NaA, NaY, Silicalite-1, and ZSM-5 were greatly accelerated. time NaA significantly decreased to 18 h under γ-ray at 20 °C, while more than 102 needed for the conventional process. Unexpectedly, mesopores created during this process, thus adsorption capacity CO2 increased by 6-fold compared prepared without irradiation. Solid experimental evidence density function theory (DFT) calculations...
The synthesis of dimethyl carbonate (DMC) from urea and methanol was investigated, to explore the catalysts reaction conditions. Among catalysts, ZnO showed highest catalytic activity toward DMC synthesis. Based on experimental investigation, conditions over for a batch process were optimized, yield attained (based urea) ∼30%, because presence side reactions. In addition, reusability test indicated that had high stability.
Reaction equilibrium for the dimethyl carbonate (DMC) synthesis from urea and methanol was calculated based on Benson method, results showed that reaction thermodynamically unfavorable. In addition, methanolysis conformed to be a consecutive reaction. Major side reactions in DMC included thermal decomposition of between methyl carbamate (MC) DMC, which reduced yield batch process. A catalytic distillation technique proposed this study minimize unfavorable synthesis. The reached 60−70%...
ABSTRACT Expanded thermoplastic polyurethane (ETPU) bead foams were fabricated by batch foaming with supercritical CO 2 as blowing agent. On the basis of single factor investigation, response surface methodology based on Box‐Behnken Design was used to investigate influences saturation pressure, temperature, and soaking time their interactions behavior ETPU. The results showed that temperature most significant parameter affecting expansion ratio, shrinkage cell morphology Moreover, there an...
Since the maximum foaming temperature window is only about 4 °C for supercritical CO2 (scCO2) of pristine polypropylene, it important to raise melt strength polypropylene in order more easily achieve scCO2 foaming. In this work, radiation cross-linked isotactic assisted by addition a polyfunctional monomer (triallylisocyanurate, TAIC), was employed process understand benefits cross-linking. Due significantly enhanced and decreased degree crystallinity caused cross-linking, behavior...
