Article Title: Synthesis of TiO2-polymer nanocomposite in supercritical CO2 via RAFT polymerization
Article Snippet: Polymer chains of PMMA were grown from nano titania (n-TiO2) spherical surfaces by the Reversible Addition Fragmentation Chain Transfer Polymerization process (RAFT) using the green solvent, supercritical carbon dioxide (scCO2).. The RAFT agent (1), 4-cyano-4-(dodecylsulfanylthiocarbonylsulfanyl) pentanoic acid, with an available carboxyl group was first coordinated to the n-TiO2 surface, with the S]C(SC12H25) moiety subsequently used for RAFT polymerization of MMA to form the n-TiO2/PMMA nanocomposites.. The livingness of polymerization was verified using GPC, while the morphology of the nanocomposites was studied using thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and dynamic light scattering (DLS).

Article Title: Fast and calibration free determination of first order reaction kinetics in API synthesis using in-situ ATR-FTIR.
Article Snippet: In early stages of drug development only sparse amounts of the key substances are available, which is problematic for the determination of important process data like reaction kinetics.. Therefore, it is important to perform experiments as economically as possible, especially in regards to limiting compounds.. Here we demonstrate the use of a temperature step experiment enabling the determination of complete reaction kinetics in a single non-isothermal experiment.

Article Title: Synthesis and Characterization of Aliphatic Ammonium Ionenes: Aqueous Size Exclusion Chromatography for Absolute Molecular Weight Characterization
Article Snippet: Cationic aliphatic ammonium polyionenes, specifically 12,12and 6,12-ionenes, were synthesized using step-growth polymerization and aqueous-based size exclusion chromatography (SEC) coupled with multiangle laser light scattering (MALLS) revealed absolute molecular weight information.. The chromatographic separation of cationic polyelectrolytes presents many additional challenges compared to SEC of nonassociating, neutral polymers.. Therefore, an aqueous-based SEC-MALLS mobile phase composition was identified to separate these notoriously challenging polyelectrolytes in an effort to achieve absolute molecular weight analysis.

Article Title: Mechanistic Studies of the Deoxydehydration of Polyols Catalyzed by a Mo(VI) Dioxo(pyridine-2,6-dicarboxylato) Complex
Article Snippet: The need for renewable resources to displace petrochemical feedstocks is of great interest.. Deoxydehydration (DODH) reduces biomassderived polyols and diols to alkenes and dienes, possibly moving alkene production closer to carbon-neutral sources.. We report the DODH of numerous aromatic, aliphatic, and biomass model diols by a dioxo-Mo(VI) catalyst, MoO2(pyridine-2,6-dicarboxylato)(HMPA).

Article Title: Catalytic double carbonylation of epoxides to succinic anhydrides: catalyst discovery, reaction scope, and mechanism.
Article Snippet: The first catalytic method for the efficient conversion of epoxides to succinic anhydrides via onepot double carbonylation is reported.. This reaction occurs in two stages: first, the epoxide is carbonylated to a â-lactone, and then the â-lactone is subsequently carbonylated to a succinic anhydride.. This reaction is made possible by the bimetallic catalyst [(ClTPP)Al(THF)2][Co(CO)4] (1; ClTPP ) meso-tetra(4chlorophenyl)porphyrinato; THF ) tetrahydrofuran), which is highly active and selective for both epoxide and lactone carbonylation, and by the identification of a solvent that facilitates both stages.

Article Title: Phase-Equilibrium Measurements of the Polystyrene/Styrene/Carbon Dioxide Ternary System at Elevated Pressures Using ATR-FTIR Spectroscopy
Article Snippet: In this paper a novel ATR-IR spectroscopic setup for phase-equilibrium studies of polymer systems in supercritical carbon dioxide is presented.. A calibration procedure for the spectroscopic investigations has been developed and verified.. The results of isothermal phase-equilibrium measurements of the polystyrene/styrene/ carbon dioxide ternary system are presented and compared to results of wellestablished cloud-point measurements.

Article Title: Succinic anhydrides from epoxides
Article Snippet: In situ IR data were collected using a 100-mL Parr stainless steel high-pressure reactor modified for use with a Mettler-Toledo ReactIR 4000 Reaction Analysis System fitted with a SentinelTM DiCompTM High Pressure Probe, and analyzed with ReactIR software version 2.21.

Article Title: Self-Optimization of Continuous Flow Electrochemical Synthesis Using Fourier Transform Infrared Spectroscopy and Gas Chromatography.
Article Snippet: A continuous-flow electrochemical synthesis platform has been developed to enable self-optimization of reaction conditions of organic electrochemical reactions using attenuated total reflection Fourier transform infrared spectroscopy (ATR FT-IR) and gas chromatography (GC) as online real-time monitoring techniques.. We have overcome the challenges in using ATR FT-IR as the downstream analytical methods imposed when a large amount of hydrogen gas is produced from the counter electrode by designing two types of gas–liquid separators (GLS) for analysis of the product mixture flowing from the electrochemical reactor.. In particular, we report an integrated GLS with an ATR FT-IR probe at the reactor outlet to give a facile and low-cost solution to determining the concentrations of products in gas– liquid two-phase flow.
