- Résumé
- "The substitution of toxic, volatile organic solvents for ionic liquids may hold several advantages for practising conservators, as ionic liquids like 1-ethyl-3-methylimidazolium ethyl sulfate are practically non-volatile, completely non-toxic, and non-irritating. In 2013, Pacheco et al. published their results on the first use of ionic liquids as alternatives for organic solvents in the removal of varnish from painted surfaces. The results showed promise, but several time consuming applications of prohibitively expensive ionic liquids were necessary to remove test coatings. More recent research on the properties of ionic liquids as solvents suggested that binary mixtures of ionic liquids and organic solvents may prove more effective at solvating these coatings than ionic liquids alone, while only using a fractional proportion of ionic liquid. By combining the well-known properties of isopropanol with the ionic liquid 1-ethyl-3- methylimidazolium ethyl sulfate, new low-toxicity solvent mixtures may be formed that mimic the qualities of so-called ‘stronger,’ and often noxious, organic solvents. Mixtures of isopropanol and 1-ethyl-3-methylimidazolium ethyl sulfate were first characterized by spectroscopic determination of Kamlet-Taft (KAT) parameters. Solvent mixtures were then tested on naturally aged varnish sample boards made at the Canadian Conservation Institute in 1994 and several historical works in the Queen’s Masters of Art Conservation study collection. Clearance testing was undertaken with Rhodamine 123. Results suggest that this binary mixture is not effective, and that ionic liquids should be used with caution on paint surfaces due to clearance issues."
