Dissolving Carbohydrates in CO_2: Renewable Materials as CO_2-philes

摘要

The design and synthesis of inexpensive, hydrocarbon based CO_2-philic materials are of current interest as they are applicable to the utilization of liquid and supercritical CO_2 as an environmentally benign solvent. In this section, we describe the molecular interactions involved in enhancing the solubility of carbohydrates in CO_2. We propose the peracetylation of these compounds as a simple method for the preparation of inexpensive, environmentally benign CO_2-philes. Utilization of these materials as CO_2-philes combines the merits of two important green chemistry principles-environmentally benign solvents and renewable materials.
