Abstract
Physico-chem. properties of ternary sugar-based low-melting mixts. were detd. Choline chloride, urea and glucose or sorbitol, serving as sugars, were blended in various compns. The refractive index, d., viscosity, decompn. temps. and glass transition temps. were measured. Further, the influence of temp. and water content was investigated. The results show that the mixts. are liq. below room temp. and the viscosity and d. are dependent on the temp. and compn. Moreover, the viscosity decreases with increasing water content. These mixts. are biodegradable, low toxic, non-volatile, non-reactive with water and can be accomplished with low-cost materials. In consideration of these advantages and a m.p. below room temp., these low-melting mixts. can be a good alternative to ionic liqs. as well as environmentally unfriendly and toxic solvents.
