Alkyl derivatives of MEA are used in the production of surfactants, dyes, in the manufacture of drugs as a buffer substance and for the stabilization of emulsions, in the manufacture of herbicides, cosmetics, antihistamines, are also of practical interest [1]. It is widely known also as useful “acid” gases (H2S, CO2, SO2, etc.) as absorbents in the process of cleaning process for gases in oil r...

Coffee-powered chemistry: Low-grade waste heat on surfaces can be used to drive chemical reactions, including the regeneration of a CO2 capture solution. Flowing two-phase heat transfer has been implemented within microvascular systems. This stripping system can be adapted to pre-fabricated surfaces, as demonstrated by a coffee mug containing a 1.2 m long microchannel. MEA=monoethanolamine.

Amine-functionalized ZnO nanosheets were prepared through a one-step hydrothermal method by using monoethanolamine, which has a hydroxyl group, for covalent attachment on ZnO and a primary amine group to supply the amine-functionalization. We demonstrate that the terminal amine groups on ZnO surfaces substantially increase the capability of CO₂ capture via chemisorption, resulting in effective ...

Based on an extended model of Marangoni convection during absorption accompanied by chemical reaction certain characteristics of the process are studied. Thus, the probability of oscillatory modes occurring in the system is analysed, the dimensions of the convective cells are evaluated and the gas-liquid contact time necessary for the instability to appear is determined. The quantitative conclu...

The use of amine scrubbers to trap carbon dioxide from flue gas streams is one of the most promising avenues for atmospheric carbon dioxide reduction. However, modifications are necessary to efficiently scale these scrubbers for use in fossil fuel plants. Current advances in tailoring amines for CO2 capture involve improvements of bulk kinetic and thermodynamic parameters, with little considera...

Electrodeposition of multilayered semiconductors requires a bath design to electrodeposit the upper layer(s) without dissolving base below. We present herein reliable approach based on thermodynamics from viewpoint complexation with ligands. A CuO/Cu2O bilayer film was targeted as an example. searched thermodynamic database constants for ligands that could form complex Cu(II) but not Cu(I), and...
