Abstract

Deep eutectic solvents (DES) are an interesting alternative to conventional amines. Due to their biodegradability, lower toxicity and lower prices, DES are considered “more benign” sorbents for CO2 capture than ionic liquids. To study the effect of water on the properties of choline chloride (ChCl)/glycerol mixtures (1:3 on a molar basis), the density and viscosity of ChCl/Gly with different water content (30%, 40% and 50%) were measured at temperature from 293.15 K to 333.15 K at atmospheric pressure, the CO2 solubility in (ChCl/Gly) with water was determined from 293.15 K to 373.15 K and at pressure from 0.5 MPa to 3 MPa. The result shows the dramatically influence of water in the viscosity but not in the CO2 solubility and Absorption.

以胆碱为基础的DESs溶剂捕集二氧化碳

深共晶溶剂(DES)是传统胺的有趣替代品。由于其可生物降解性、低毒性和低价格，DES被认为是比离子液体“更良性”的二氧化碳捕获吸附剂。为了研究水对氯化胆碱(ChCl)/甘油(摩尔比为1:3)混合物性能的影响，在293.15 K ~ 333.15 K的常压下，测定了ChCl/Gly在30%、40%和50%含水量下的密度和粘度，在293.15 K ~ 373.15 K和0.5 MPa ~ 3mpa的压力下，测定了ChCl/Gly与水的溶解度。结果表明，水对粘度的影响较大，而对CO2的溶解度和吸收率影响较小。

期刊介绍： MATEC Web of Conferences is an Open Access publication series dedicated to archiving conference proceedings dealing with all fundamental and applied research aspects related to Materials science, Engineering and Chemistry. All engineering disciplines are covered by the aims and scope of the journal: civil, naval, mechanical, chemical, and electrical engineering as well as nanotechnology and metrology. The journal concerns also all materials in regard to their physical-chemical characterization, implementation, resistance in their environment… Other subdisciples of chemistry, such as analytical chemistry, petrochemistry, organic chemistry…, and even pharmacology, are also welcome. MATEC Web of Conferences offers a wide range of services from the organization of the submission of conference proceedings to the worldwide dissemination of the conference papers. It provides an efficient archiving solution, ensuring maximum exposure and wide indexing of scientific conference proceedings. Proceedings are published under the scientific responsibility of the conference editors.
