Natural gas sweetening is an important process which is used for treatment of sour gases. The measurement of solubility is also considered in most sweetening processes such as that of Townsend process. Therefore, experimental measurements would be helpful to determine the equilibrium data under actual equilibrium conditions for the gas treatment plants. In this research solubility of hydrogen s...

In the title solvate, C19H13N5O·0.5C4H8O2, the main mol-ecule is almost planar (r.m.s. deviation for the non-H atoms = 0.066 Å). The hydroxyl-amine group is disordered over two orientations in a 0.761 (4):0.239 (4) ratio. The complete dioxane solvent mol-ecule is generated by a crystallographic inversion centre. In the crystal, both disorder components of the hydroxyl-amine group form O-H⋯N hyd...

Ionic liquids can be used as solvents for gas absorption operations in order to improve the process economy and general efficiency of gas separations. This work investigates solvent properties of ionic liquids and compares them to amine solutions used for absorption of carbon dioxide (CO2). The CO2 solubility into imidazolium-based Room Temperature Ionic Liquids (RTILs) was measured at temperat...

Amine is one of candidate solvents that can be used for CO2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO2 recovery plant for post-combustion CO2 removal. For each amine solvent, ...

The asymmetric unit of the title compound {systematic name: cis-dichloridobis[(3,7-dimethylbicyclo-[3.3.1]non-1-ylmeth-yl)-amine-κN]platinum(II) N,N-dimethyl-formamide solvate}, [PtCl(2)(C(11)H(19)N)(2)]·C(3)H(7)NO, consists of two metrically similar Pt complexes and two dimethyl-formamide solvent mol-ecules. Each Pt(II) center is coordinated by the amine groups of two (1-adamantylmeth-yl)amine...

[figure: see text] Chelation and aggregation in phenyllithium reagents with potential 5-, 6-, and 7-ring chelating ether and amine ortho substituents have been examined utilizing variable-temperature 6Li and 13C NMR spectroscopy, 6Li and 15N isotope labeling, and the effects of solvent additives. Both ether and amine form strong 5-ring chelates; 6-ring ether chelates compete well with THF, but ...

This study used monoethanolamine (MEA) as an amine-based solvent, which was blended with secondary amines (DIPA), tertiary amines, stereo and piperazine (PZ) to prepare mixed at the required concentrations, were test solvents. To search for best-mixed a continuous bubble-column scrubber adopted explore performance of solvents presented in this study. The solvent regeneration also carried out di...

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.

A solution of urea, sulphur dioxide and sodium salicylate in methanol is proposed as the solvent in the Karl Fischer titration, with a separate iodine solution as titrant. Comparison of the performance of this solvent with that of some commercial reagents shows that it is has distinct advantages for use with amine samples.
