Eutectic mixture of choline chloride/urea as a green solvent in synthesis of a coordination polymer: [Zn(O3PCH2CO2)]·NH4

Applications of functionalized ionic liquids

“…A choline chloride/urea eutectic mixture has also been employed as solvent in the preparation of a new zeotype framework derived from Al(OiPr) 3 formed during the reaction, the NH 4 + cation formed on the partial decomposition of urea acts to template the structure and balance the charge distribution of the framework, and the procedure is termed as "ionothermal" synthesis for distinguishing from other preparations. The choline chloride/urea eutectic mixture was also employed as solvent for a zinc coordination polymer in a recent report [130] . Zn(NO 3 ) 2 ·6(H 2 O) and H 2 O 3 PCH 2 CO 2 H reacted in the choline chloride/urea eutectic mixture to give a Zn(O 3 PCH 2 CO 2 )NH 4 .…”

Electrodeposition of zinc–tin alloys from deep eutectic solvents based on choline chloride

“…The use of simple amides, acids and alcohols as complexing agents makes the liquids very versatile and to distinguish them from other ionic liquids the term deep eutectic solvents (DES) has been coined. DESs have been used for electropolishing [13], polymer synthesis [14] and metal oxide processing [15]. Most of our previous studies have concentrated on choline chloride as the quaternary ammonium salt as it is non-toxic, biodegradable and is already used as a common component to numerous household and industrial products.…”

Deep Eutectic Solvents Playing Multiple Roles in the Synthesis of Porous Carbon Materials

“…Moreover, the eco-friendly and low-toxic character of some DESs has allowed their use as solvents for both natural and synthetic membrane-like structures [32] and proteins [33][34][35][36] and even for whole microorganisms [37] with preservation of their intrinsic activity. Examples of materials prepared from "all-in-one" DESs include metal phosphates [38], oxalatophosphates [39], aluminophosphates [40,41], carboxymethylphosphonates [42], oxalatophosphonates [43], polyoxometalate-based hybrids [44], zeolites [45], or metal-organic frameworks (MOFs) [46]. Readers are referred to the review published by Morris and coworkers for further information on ionothermal syntheses of zeolites, MOFs, and inorganic-organic hybrids [47].…”
