The knowledge regarding the synthesis of new organic derivatives with controlled morphology on the basis of kaolin group minerals is increasing. Apart from kaolinite, new materials were obtained using halloysite. However, organic derivatives of dickite are not well known. In this study dickite w...

In this paper the influence of hexylamine, as an example of a short chain alkyl amine, on the flotation behaviour and interfacial properties of quartz was investigated. It was shown that hexylamine enhanced the flotation performance of quartz regardless of the type of flotation device. The foami...

Ionic liquids are finding a wide range of applications from reaction media to separations and materials processing. In order to provide larger quantities of ionic liquids, a sustainable synthesis method is needed which includes optimization of the separation of the reaction mixture, possibly usi...

The use of carbon dioxide in the synthesis of ionic liquids (ILs) has many advantages over conventional solvents. Here, the high-pressure phase equilibria (including CO2 solubility, volume expansion, and mixture critical points) are measured and modeled for the system involved in the synthesis o...

The Raman and IR spectra of 1,5-dichloro- and 1,5-dibromopentanes and 1,6-dichloro-and 1,6-dibromohexanes have been measured. The normal coordinates have been calculated for these molecules using a consistent set of force constants and the molecular conformations studied by analysing the spectra...

Attempts to bridge a calix[4]arene with a three-carbon bridge using 1,3-dibromopropane and NaH/DMF led to elimination reactions. Using K2CO3/CH3CN, three new calixarenes were obtained: a biscalixarene (8), a novel bridged calixarene (9), and a partial cone calixarene (10). Attempts to bridge a c...

A CO2-facilitated transport composite membrane made of PVAm/PVA blend was exposed to a humid synthetic natural gas mixture with monoethylene glycol (MEG) and triethylene glycol (TEG). The effects of different parameters such as relative humidity, types of impurities, exposure temperature were an...

In natural gas sweetening, gas dehydration with glycols is typically carried out upstream of membrane separation of carbon dioxide. This means that when process upsets occur, these glycols can reach the membrane unit. In this work, we study the impact of two common glycols (monoethylene glycol a...
