Description

General description

Cholin acetate is a choline-derivative-based ionic liquid (IL), which can efficiently dissolve microcrystalline cellulose. This bioionic liquid can be prepared by reacting choline hydroxide with acetic acid.

Application

Cholin acetate in combination with glycerol, a hydrogen-bond donor forms a eutectic ionic liquid mixture, which is less viscous, biodegradable and also shows high lipase compatibility. This eutectic ionic liquid mixture can be a desirable solvent for the enzymatic production of biodiesel.
