Separation of CO2 and TFE by using diethanolamine and diisopropylamine

Muhammad Salman, Elia Mercedes Ruiz Pachon

The near-azeotrope mixture of TFE and CO2 is an important concern urging the scientific community to develop new ways for TFE/CO2 separations. In this work, for the first time, Diisopropylamine (DIPA) and Diethanolamine (DEA) are used as solvents for separ ...

CO2 Capture and Release in Amine Solutions: To What Extent Can Molecular Simulations Help Understand the Trends?

Wanda Andreoni, Fabio Pietrucci, Changru Ma

Absorption in amine solutions is a well-established advanced technology for CO2 capture. However, the fundamental aspects of the chemical reactions occurring in solution still appear to be unclear. Our previous investigation of aqueous monoethanolamine (ME ...

Experimental and modeling-based analysis of reaction pathways on catalysts for natural gas engines under periodic lean/rich oscillations

Davide Ferri, Oliver Kröcher, Moyu Wang

Methane (CH4) has the prospective of becoming one of the major energy carriers for heavy-duty mobility, but its catalytic abatement remains a challenge. CH4 abatement reaction pathways were analyzed using targeted periodic lean/rich oscillations, which res ...

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Alexandre Bagnoud

Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to res ...

Quantification of amine functional groups and their influence on OM/OC in the IMPROVE network

Satoshi Takahama

Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C = O, in atmospheric parti ...

Nickel-Catalyzed Reductive Transamidation of Secondary Amides with Nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Transmidation is an attractive method for amide synthesis. However, transamidation of secondary amides is challenging. Here, we describe a reductive transamidation method that employs readily available nitro(hetero)arenes as the nitrogen sources, zinc or m ...

Reaction dynamics of in aqueous amines from ab initio molecular dynamics: 2-amino-2-methyl-1,3-propanediol (AMPD) compared to monoethanolamine (MEA)

Wanda Andreoni, Fabio Pietrucci, Changru Ma

We present Car-Parrinello molecular dynamics simulations-combined with metadynamics-of the reactions accompanying the capture of in an aqueous amine solution. The selected amine is 2-amino-2-methyl-1,3-propanediol, which has been investigated experimentall ...

CO2 capture in amine solutions: modelling and simulations with non-empirical methods

Wanda Andreoni, Fabio Pietrucci

Absorption in aqueous amine solutions is the most advanced technology for the capture of CO2, although suffering from drawbacks that do not allow exploitation on large scale. The search for optimum solvents has been pursued with empirical methods and has a ...

Capturing CO2 in Monoethanolamine (MEA) Aqueous Solutions: Fingerprints of Carbamate Formation Assessed with First-Principles Simulations

Wanda Andreoni, Fabio Pietrucci, Changru Ma

Chemical absorption in amine aqueous solutions is a widespread technology for postcombustion carbon capture, and a large effort is ongoing to improve their performance. Characterization of the "reactant" and "product" solutions at the microscopic level is ...

Amides in One Pot from Carboxylic Acids and Amines via Sulfinylamides

Pierre Vogel, Jianfei Bai

An efficient method has been developed for the direct amidification of carboxylic acids via sulfinylamides preformed in situ by the reaction of pure amines with prop-2-ene-1-sulfinyl chloride. The method can be applied to aliphatic acids, including pivalic ...
