Copper Electrodeposition from a Water-Containing Choline Chloride Based Deep Eutectic Solvent

This study investigated the effect of water on the physical and electrochemical properties of a choline chloride deep eutectic solvent (DES). Physical and electrochemical measurements were performed on the DES containing varying amounts of water. When the water content was increased from 1% to 15 wt%, the viscosity and density declined while the conductivity increased significantly. Similarly, ...

Deep Eutectic Solvent Based on Choline Chloride/Urea as an Efficient Catalytic System for the One-Pot Synthesis of Highly Functionalized 1,4-Dihydropyridines and Polysubstituted 4H-Chromenes

One-pot four-component synthesis of polyfunctionalized 1,4-dihydropyridine derivatives was developed by a condensation of aldehydes, malononitrile, diethylacetylenedicarboxylate and aniline in the presence of choline chloride/urea as a deep eutectic solvent (DES)at room temperature.Moreover, an efficient method was reported for the synthesis of highly substituted 4H-chromenes through one-...

Biodegradable Nanocomposite Films Based on Sodium Alginate and Cellulose Nanofibrils

Biodegradable nanocomposite films were prepared by incorporation of cellulose nanofibrils (CNF) into alginate biopolymer using the solution casting method. The effects of CNF content (2.5, 5, 7.5, 10 and 15 wt %) on mechanical, biodegradability and swelling behavior of the nanocomposite films were determined. The results showed that the tensile modulus value of the nanocomposite films increased...

Efficient Synthesis of Dihydropyrimidine and Amidoalkyl Naphthol Derivatives Using Zinc Chloride-Based Deep Eutectic Systems as Solvent & Catalyst

Dihydropyrimidine and amidoalkyl naphthol derivatives have been prepared efficiently in a one-pot synthesis using ZnCl2/urea and ZnCl2/acetamide deep eutectic systems as reaction medium and homogeneous catalyst. This method offers some advantages such as simple procedure, inexpensive solvent and catalyst and good yields of the final products in short reaction times. The use of non-toxic and env...
