One of the most significant deep eutectic phenomenon was observed for a mixture of choline chloride and urea in a 12 mole ratio.
Choline chloride urea. Densities and dynamic viscosities of a common and popular des composed of choline chloride and urea in 12 molar ratio named reline and its aqueous mixtures in the temperature range 29315 k to 36315 k are reported. Density conductivity and viscosity measurements were performed for all obtained mixtures. The freezing point of the eutectic mixture is 12 0c which is considerably lower than that of either of the constituents mp choline chloride 302 0c and urea 133 0c and allows the mixture to be used as an ambient temperature solvent.
Our main products are choline chloride choline bitartrate betaine anhydrous betaine hydrochloride dmae bitartrate calcuim pyruvate urea and etc. The resulting mixture has a melting point of 12 0c far less than the melting point of choline 302 0c and urea 133 0c which makes it liquid at room temperature.

Recently choline chlorideurea chclurea a typical deep eutectic solvent des has been found to possess various applications in organic synthesis electrochemistry and nanomaterial preparation. Herein we reported the first attempt to plasticize regenerated cellulose film rcf using chclurea as an effective plasticizer. All answers 10 it turned out that choline glutaratecholine chloride mixtures are liquids at room temperature at compositions containing 9598 wt of choline glutarate.
Aqueous mixtures of dess have the potential to afford modified properties for specific applications.
