“…Because of that, the unsaturated alcohols and alkenyl halides were treated with various thiols (Table 2). Sulfides containing hydroxy or halide groups are known as useful reagents for the synthesis of complex organic molecules 48–52. The addition of thiols to unsaturated alcohols proceeded with good yields (80–95 %).…”

Carbamate Stabilities of Sterically Hindered Amines from Quantum Chemical Methods: Relevance for CO₂ Capture

2013

The influence of electronic and steric effects on the stabilities of carbamates formed from the reaction of CO2 with a wide range of alkanolamines was investigated by quantum chemical methods. For the calculations, B3LYP, M11-L, MP2, and spin-component-scaled MP2 (SCS-MP2) methods were used, coupled with SMD and SM8 solvation models. A reduction in carbamate stability leads to an increased CO2 absorption capacity of the amine and a reduction of the energy required for solvent regeneration. Important factors for the reduction of the carbamate stability were an increase in steric hindrance around the nitrogen atom, charge on the N atom and intramolecular hydrogen bond strength. The present study indicates that secondary ethanolamines with sterically hindering groups near the N atom show significant potential as candidates for industrial CO2-capture solvents.

“…This behaviour can be explained by exothermic sorption character. Previous batch experiments revealed physisorption of Pt IV [5]. This kind of mechanism is always exothermic because the increasing arrangement of adsorbate on adsorbent surface reduces entropy.…”

“…Polystyrene (PS) is an amorphous and glassy polymer with highly ordered structures solely constructed by the polymerization of styrene. Owing to its strong covalent linkages between light elements (H and C), PS possesses many unique features such as low density, ease of handling, negligible solubility in water, nonbiodegradability, and nontoxicity, which make it applicable to diverse fields including wastewater treatment, − chromatographic separation, − solid-phase extraction, − and adsorption of proteins/peptides. − …”

Sub-ppt Mass Spectrometric Detection of Therapeutic Drugs in Complex Biological Matrixes Using Polystyrene-Microsphere-Coated Paper Spray

et al. 2017

Polystyrene (PS) is a class of polymer materials that offers great potential for various applications. However, the applications of PS microspheres in paper spray mass spectrometry are largely underexplored. Herein we prepared a series of PS microspheres via a simple dispersion polymerization and then used them as coating materials for paper spray mass spectrometry (MS) in high-sensitivity analysis of various therapeutic drugs in complex biological matrixes. In the preparation of PS-coated papers, the coating method was found playing a key role in determining the performance of the resulting paper substrate in addition to other parameters (e.g., starch type and amount, PS coating amount, and spray solvent). We also found that as a solvent was applied on PS-coated paper for paper spray, the analytes of interest would be first extracted out and then moved to the tip of paper triangle for spray along with the applied solvent. In the process, the surface energy of PS particles had a strong impact on the desorption performance of analytes from PS-coated paper substrate, and the PS with a high surface energy favored the elution of analytes to allow a high MS sensitivity. When the prepared PS coated paper was used as a substrate for paper spray, it gave high sensitivity in analysis of therapeutic drugs in various biological matrixes such as whole blood, serum, and urine with excellent repeatability and reproducibility. In contrast to uncoated filter paper, an improvement of 10-546-fold in sensitivity was achieved using PS-coated paper for paper spray, and an estimated lower limit of quantitation (LLOQs) in the range of 0.004-0.084 ng mL was obtained. The present study is significant in exploring the potential of PS for high-sensitivity MS analysis, and it provides a promising platform in the translation of the MS technique to clinical applications.
