Environmentally Friendly Method

An environmentally friendly method for alkylating aromatic compounds with simple alcohols in the presence of a catalytic amount of indium(III) triflate is reported. Ionic liquids are used as solvents and energy-efficient heating is provided by microwave radiation. Good yields are obtained with benzyl, secondary, and tertiary alcohols. Simple primary alcohols are not effective alkylating agents under these conditions. With tertiary alcohols, activated aromatic compounds such as toluene and anisole must be used to obtain good yields. The catalyst, which is immobilized in a water-insoluble ionic liquid, can be easily recycled without significant loss of activity.

Lithium salts were dissolved in ionic liquid [Amim]Cl, and their dissolution behavior were tested by turbidimeter. It is found that the solubility of LiCl in [Amim]Cl is up to 14g/100g [Amim]Cl at 70°C, and it keeps growing as the temperature increase. Turbidity of cellulose solution in [Amim]Cl at 70°C was obtained, but the solubility of high concentration cellulose solution could not be demonstrated accurately in this way. Cellulose solutions with [Amim]Cl or [Amim]Cl/lithium salts as solvents at different temperature were obtained, in which the lithium salts were 1wt%(mass fraction of [Amim]Cl), polarization microscope was used to observe the dissolution behavior of cellulose. The solubility of cellulose would increased as temperature rose, and the solubility of cellulose in [Amim]Cl/1wt%LiCl reached 11.9%(mass fraction of [Amim]Cl) at 80°C, which was higher than in [Amim]Cl 9.4% at 80°C. It is found that the addition of lithium salts into [Amim]Cl can really improve the solubility of cellulose than in [Amim]Cl.
