Abstract

The prepn. and characterization of a series of ionic liqs. based on S-alkylthiouronium cations prepd. from thiourea, 1,3-dimethylthiourea, 1,3-diethylthiourea and 1,3-tetramethylthiourea coupled with bis{(trifluoromethane)sulfonyl}imide, bromide, methylsulfate or ethylsulfate anions are reported. All are liqs. at room temp. or solids with m.ps. close to room temp., except for the bromide salts, which have m.ps. below 92 °C. Systematic variation in the N- and S-alkyl substituents demonstrates how the phys. properties of these ionic liqs. can be readily controlled. The mutual miscibility limits of representative examples with octane, dodecane and toluene have been detd. as a function of temp., and the extn. of dibenzothiophene from dodecane as a model for desulfurisation of diesel has been investigated.
