Abstract
Lactamium based ionic liquids and methods of making them are described. The ionic liquids comprise at least one of: the reaction product of a lactam compound having a general formula wherein the ring has at least one C≡C double bond, or and a Brønsted acid HX; or a Brønsted acid HX where X is a halide, and a metal halide.
Claims1
A lactamium based ionic liquid consisting of:
- a reaction product of a lactam compound having a formula
- wherein R is an alkyl group having from 1 to 12 carbon atoms, n is 3;
- and a Brønsted acid HX where X is a halide, and a metal halide where the reaction product is a halometallate.
