Abstract
The novel multi-SO3H functionalized strong Brønsted acidic ionic liquid has been prepared and its catalytic activities were investigated through the acetalization. The results showed that the novel catalyst was very efficient for the reaction with the average yield over 90% under solvent-free condition at room temperature. Operational simplicity, without need of any solvent, a small amount of usage, low cost of the catalyst used, high yields, applicability to large-scale reactions and reusability are the key features of this methodology. The novel catalyst also has great potential for the green process.
