Abstract
A method and related packaged product for forming a surface treatment liquid involves contacting two solids to form a liquid, particularly an ionic liquid under ambient conditions at the locus of use.
Claims15
1) A method of forming a surface treatment liquid comprising bringing into mutual contact a first solid and a second solid wherein the first and second solids interact upon mutual contact to form a liquid characterised in that the method is carried out at the locus of use.
2) A method of treating a surface comprising the application of a first solid and a second solid to the surface whereby the two solids are brought into mutual contact with each other and with the surface and wherein the first and second solids interact upon mutual contact to form a liquid.
3) A method of cleaning a surface comprising the sequential steps:
- i) the application of a first solid and a second solid to the surface whereby the two solids are brought into mutual contact with each other and with the surface and wherein the first and second solids interact upon mutual contact to form a liquid
- ii) cleaning the surface with the liquid and
- iii) removal of liquid and soil from the surface.
5) A method according to any preceding claim wherein the melting point of the first solid is 40° C. or more, the melting point of the second solid is 40° C. or more and the freezing point of the liquid is 20° C. or less.
6) A method according to any preceding claim wherein the liquid is an ionic liquid.
7) A method according to any preceding claim wherein the first solid comprises a quaternary ammonium compound according to formula I
- R1R2R3R4N+X− I
- wherein R1, R2 and R3 are each independently hydrogen, a C1 to C5 alkyl or a C6 to C10 cycloalkyl group or wherein R2 and R3 taken together represent a C4 to C10 alkylene group such that R2R3 and the N atom of formula I form a 5- to 11-membered heterocyclic ring,
- and wherein R4 differs from any of R1, R2 and R3 and is hydrogen, a C6 to C12 alkyl or cycloalkyl group substituted with at least one substituent selected from the group consisting of OH, Cl, Br, F, I, NH2, CN, NO, COORS, CHO, COR and OR5 wherein R5 is a C1 to C10 alkyl or cycloalkyl group,
- and X− is a halogen or methosulphate counter-ion.
