Regeneration of caprolactam-based Brønsted acidic ionic liquid during transesterification of Jatropha oil

[Display omitted] •The major cause of IL deactivation was the loss of acidity.•There was a negative linear correlation between acidity decline rate and biodiesel yield.•Deactivated IL was regenerated successfully by supplementing acidity with H2SO4. As catalysts for biodiesel preparation, functional...
