The catalytic conversion of crude glycerol to biopropene was investigated. A bifunctional Ru-ionic liquid system showed a high tolerance for common crude glycerol impurities like water, salts and methanol. After optimizing both dehydration and olefin selectivity, a 82% biopropene yield (94% selectivity) was obtained directly from industrial waste glycerol.
